from web contents: Dealing with low-quality backlinks 2013

salam every one, this is a topic from google web master centrale blog: Webmaster level: Intermediate/Advanced

Webmasters who check their incoming links in Webmaster Tools often ask us what they can do when they see low-quality links. Understandably, many site owners are trying to build a good reputation for their sites, and some believe that having poor-quality incoming links can be perceived as "being part of a bad neighbourhood," which over time might harm their site's ranking.

example of low-quality links
If your site receives links that look similarly dodgy, don't be alarmed... read on!

While it's true that linking is a significant factor in Google's ranking algorithms, it's just one of many. I know we say it a lot, but having something that people want to look at or use—unique, engaging content, or useful tools and services—is also a huge factor. Other factors can include how a site is structured, whether the words of a user's query appear in the title, how close the words are on the page, and so on. The point is, if you happen to see some low quality sites linking to you, it's important to keep in mind that linking is just one aspect among many of how Google judges your site. If you have a well-structured and regularly maintained site with original, high-quality content, those are the sorts of things that users will see and appreciate.

That having said, in an ideal world you could have your cake and eat it too (or rather, you could have a high-quality site and high-quality backlinks). You may also be concerned about users' perception of your site if they come across it via a batch of spammy links. If the number of poor-quality links is manageable, and/or if it looks easy to opt-out or get those links removed from the site that's linking to you, it may be worth it to try to contact the site(s) and ask them to remove their links. Remember that this isn't something that Google can do for you; we index content that we find online, but we don't control that content or who's linking to you.

If you run into some uncooperative site owners, however, don't fret for too long. Instead, focus on things that are under your control. Generally, you as a webmaster don't have much control over things like who links to your site. You do, however, have control over many other factors that influence indexing and ranking. Organize your content; do a mini-usability study with family or friends. Ask for a site review in your favorite webmaster forums. Use a website testing tool to figure out what gets you the most readers, or the biggest sales. Take inspiration from your favorite sites, or your competitors—what do they do well? What makes you want to keep coming back to their sites, or share them with your friends? What can you learn from them? Time spent on any of these activities is likely to have a larger impact on your site's overall performance than time spent trying to hunt down and remove every last questionable backlink.

Finally, keep in mind that low-quality links rarely stand the test of time, and may disappear from our link graph relatively quickly. They may even already be being discounted by our algorithms. If you want to make sure Google knows about these links and is valuing them appropriately, feel free to bring them to our attention using either our spam report or our paid links report.

from web contents: Updates to rich snippets 2013

salam every one, this is a topic from google web master centrale blog: Webmaster level: All

Today we’re announcing two updates to rich snippets.

First, we’re happy to announce that product rich snippets, which previously were only available in a limited set of locales, are supported globally.  Users viewing your site’s results in Google search can now preview information about products available on your website, regardless of where they’re searching from. Here’s an example of a product rich snippet:
A product rich snippet from www.google.fr
Second, we’ve updated the rich snippets testing tool to support HTML input. We heard from many users that they wanted to be able to test their HTML source without having to publish it to a web page. This is now supported by the tool, as shown below.
Preview rich snippets from HTML source
If you have any questions or feedback about these changes, please let us know in our Help Forum. You can find more information about rich snippets in our Help Center and Webmaster Education site.

from web contents: Back from SES San Jose 2013

salam every one, this is a topic from google web master centrale blog: Thanks to everyone who stopped by to say hi at the Search Engine Strategies conference in San Jose last week!

I had a great time meeting people and talking about our new webmaster tools. I got to hear a lot of feedback about what webmasters liked, didn't like, and wanted to see in our Webmaster Central site. For those of you who couldn't make it or didn't find me at the conference, please feel free to post your comments and suggestions in our discussion group. I do want to hear about what you don't understand or what you want changed so I can make our webmaster tools as useful as possible.

Some of the highlights from the week:

This year, Danny Sullivan invited some of us from the team to "chat and chew" during a lunch hour panel discussion. Anyone interested in hearing about Google's webmaster tools was welcome to come and many did -- thanks for joining us! I loved showing off our product, answering questions, and getting feedback about what to work on next. Many people had already tried Sitemaps, but hadn't seen the new features like Preferred domain and full crawling errors.

One of the questions I heard more than once at the lunch was about how big a Sitemap can be, and how to use Sitemaps with very large websites. Since Google can handle all of your URLs, the goal of Sitemaps is to tell us about all of them. A Sitemap file can contain up to 50,000 URLs and should be no larger than 10MB when uncompressed. But if you have more URLs than this, simply break them up into several smaller Sitemaps and tell us about them all. You can create a Sitemap Index file, which is just a list of all your Sitemaps, to make managing several Sitemaps a little easier.

While hanging out at the Google booth I got another interesting question: One site owner told me that his site is listed in Google, but its description in the search results wasn't exactly what he wanted. (We were using the description of his site listed in the Open Directory Project.) He asked how to remove this description from Google's search results. Vanessa Fox knew the answer! To specifically prevent Google from using the Open Directory for a page's title and description, use the following meta tag:
<meta name="GOOGLEBOT" content="NOODP">

My favorite panel of the week was definitely Pimp My Site. The whole group was dressed to match the theme as they gave some great advice to webmasters. Dax Herrera, the coolest "pimp" up there (and a fantastic piano player), mentioned that a lot of sites don't explain their product clearly on each page. For instance, when pimping Flutter Fetti, there were many instances when all the site had to do was add the word "confetti" to the product description to make it clear to search engines and to users reaching the page exactly what a Flutter Fetti stick is.

Another site pimped was a Yahoo! Stores web site. Someone from the audience asked if the webmaster could set up a Google Sitemap for their store. As Rob Snell pointed out, it's very simple: Yahoo! Stores will create a Google Sitemap for your website automatically, and even verify your ownership of the site in our webmaster tools.

Finally, if you didn't attend the Google dance, you missed out! There were Googlers dancing, eating, and having a great time with all the conference attendees. Vanessa Fox represented my team at the Meet the Google Engineers hour that we held during the dance, and I heard Matt Cutts even starred in a music video! While demo-ing Webmaster Central over in the labs area, someone asked me about the ability to share site information across multiple accounts. We associate your site verification with your Google Account, and allow multiple accounts to verify ownership of a site independently. Each account has its own verification file or meta tag, and you can remove them at any time and re-verify your site to revoke verification of a user. This means that your marketing person, your techie, and your SEO consultant can each verify the same site with their own Google Account. And if you start managing a site that someone else used to manage, all you have to do is add that site to your account and verify site ownership. You don't need to transfer the account information from the person who previously managed it.

Thanks to everyone who visited and gave us feedback. It was great to meet you!this is a topic published in 2013... to get contents for your blog or your forum, just contact me at: devnasser@gmail.com

from web contents: Introducing new and improved sitelinks 2013

salam every one, this is a topic from google web master centrale blog: Webmaster level: All



This week we launched an update to sitelinks to improve the organization and quality of our search results. Sitelinks are the two columns of links that appear under some search results and ads that help users easily navigate deeper into the site. Sitelinks haven’t changed fundamentally: they’re still generated and ranked algorithmically based on the link structure of your site, and they’ll only appear if useful for a particular query.





Sitelinks before today’s changes


Here’s how we’ve improved sitelinks with today’s launch:

  • Visibility. The links have been boosted to full-sized text, and augmented with a green URL and one line of text snippet, much like regular search results. This increases the prominence of both the individual sitelinks and the top site overall, making them easier to find.


  • Flexibility. Until now, each site had a fixed list of sitelinks that would either all appear or not appear; there was no query-specific ranking of the links. With today’s launch, sitelink selection and ranking can change from query to query, allowing more optimized results. In addition, the maximum number of sitelinks that can appear for a site has been raised from eight to 12, and the number shown also varies by query.


  • Clarity. Previously, pages from your site could either appear in the sitelinks, in the regular results, or both. Now we’re making the separation between the top domain and other domains a bit clearer. If sitelinks appear for the top result, then the rest of the results below them will be from other domains. One exception to this is if the top result for a query is a subpart of a domain. For instance, the query [the met exhibitions] has www.metmuseum.org/special/ as the top result, and its sitelinks are all from within the www.metmuseum.org/special section of the site. However, the rest of the results may be from other parts of the metmuseum.org domain, like store.metmuseum.org or blog.metmuseum.org/alexandermcqueen/about.


  • Quality. These user-visible changes are accompanied by quality improvements behind the scenes. The core improvement is that we’ve combined the signals we use for sitelinks generation and ranking -- like the link structure of your site -- with our more traditional ranking system, creating a better, unified algorithm. From a ranking perspective, there’s really no separation between “regular” results and sitelinks anymore.


Sitelinks after today’s changes


These changes are also reflected in Webmaster Tools, where you can manage the sitelinks that appear for your site. You can now suggest a demotion to a sitelink if it’s inappropriate or incorrect, and the algorithms will take these demotions into account when showing and ranking the links (although removal is not guaranteed). Since sitelinks can vary over time and by query, it no longer makes sense to select from a set list of links -- now, you can suggest a demotion of any URL for any parent page. Up to 100 demotions will be allowed per site. Finally, all current sitelink blocks in Webmaster Tools will automatically be converted to the demotions system. More information can be found in our Webmaster Tools Help Center.



It’s also worth mentioning a few things that haven’t changed. One-line sitelinks, where sitelinks can appear as a row of links on multiple results, and sitelinks on ads aren’t affected. Existing best practices for the link structure of your site are still relevant today, both for generating good quality sitelinks and to make it easier for your visitors. And, as always, you can raise any questions or comments in our Webmaster Help Forum.

from web contents: One-line sitelinks 2013

salam every one, this is a topic from google web master centrale blog:
Webmaster Level: All

You may be familiar with sitelinks, the links that show up underneath the first search result and which lead to specific pages deeper within the site. Sitelinks enable users to jump directly to important parts of a site, which is often useful for large, complex websites. Sitelinks have the additional advantage of giving users an overview of a website's content by highlighting some of the popular parts of the site. For webmasters, sitelinks are also beneficial because they help to expose parts of your site that users may not know about. For instance, a search for NASA provides links to a gallery of images, a page about Space Shuttle and ISS missions, and so on:


Until now, sitelinks have only ever appeared on the first search result, and so at most one site could have sitelinks per query. We're now launching an expansion of sitelinks: a single row of links can now appear for results that didn't show sitelinks before, even for results that aren't in the first position. This means multiple results on one query can now have sitelinks. Up to four sitelinks can show up right above the page URL, instead of the usual two columns below the URL of the first result. Here's an example where the first three results each have one-line sitelinks:


These one-line sitelinks have many of the same benefits as the full two-column sitelinks, but on a smaller scale: they show users some relevant sub-pages in the site and give an idea of what the site is about. Comparing the sitelinks that appear for each result can even illustrate the difference between the sites. Just like regular sitelinks, one-line sitelinks are generated algorithmically and the decisions on when to show them and which links to display are entirely based on the expected benefit to users.

For webmasters, this new feature means it's possible that your site will start showing sitelinks for a number of queries where it previously didn't. We expect this will increase the visibility of and traffic to your site, while also improving the experience of users. If, however, you absolutely would prefer not to have a particular sitelink show up, remember that you can always block a page from appearing as a sitelink for 90 days through Webmaster Tools. In fact, as part of our ongoing efforts at improving the Webmaster Tools experience, we're speeding up our response time to blocked pages, so you should see a blocked page get dropped as a sitelink even faster than before. If you need a quick refresher on how to use the sitelink blocking tool, take a look at this previous blog post. Currently you can only block sitelinks on your site's home page, but we're working on expanding this capability so you'll soon be able to remove them from any other page as well.

We hope you find these improvements to sitelinks and Webmaster Tools helpful for both your site and your visitors!

from web contents: Rich Snippets Instructional Videos 2013

salam every one, this is a topic from google web master centrale blog: Webmaster level: All

When users come to Google, they have a pretty good idea of what they’re looking for, but they need help deciding which result might have the information that best suits their needs. So, the challenge for Google is to make it very clear to our users what content exists on a page in both a useful and concise manner. That’s why we have rich snippets.


Essentially, rich snippets provide you with the ability to help Google highlight aspects of your page. Whether your site contains information about products, recipes, events or apps, a few simple additions to your markup can result in more engagement with your content -- and potentially more traffic to your site.

To help you get started or fine tune your rich snippets, we’ve put together a series of tutorial videos for webmasters of all experience levels. These videos provide guidance as you mark up your site so that Google is better able to understand your content. We can use that content to power the rich snippets we display for your pages. Check out the videos below to get started:

from web contents: Managing your reputation through search results 2013

salam every one, this is a topic from google web master centrale blog: (Cross-posted on the Official Google Blog)

A few years ago I couldn't wait to get married. Because I was in love, yeah; but more importantly, so that I could take my husband's name and people would stop getting that ridiculous picture from college as a top result when they searched for me on Google.

After a few years of working here, though, I've learned that you don't have to change your name just because it brings up some embarrassing search results. Below are some tips for "reputation management": influencing how you're perceived online, and what information is available relating to you.

Think twice

The first step in reputation management is preemptive: Think twice before putting your personal information online. Remember that although something might be appropriate for the context in which you're publishing it, search engines can make it very easy to find that information later, out of context, including by people who don't normally visit the site where you originally posted it. Translation: don't assume that just because your mom doesn't read your blog, she'll never see that post about the new tattoo you're hiding from her.

Tackle it at the source

If something you dislike has already been published, the next step is to try to remove it from the site where it's appearing. Rather than immediately contacting Google, it's important to first remove it from the site where it's being published. Google doesn't own the Internet; our search results simply reflect what's already out there on the web. Whether or not the content appears in Google's search results, people are still going to be able to access it — on the original site, through other search engines, through social networking sites, etc. — if you don't remove it from the original site. You need to tackle this at the source.
  • If the content in question is on a site you own, easy — just remove it. It will naturally drop out of search results after we recrawl the page and discover the change.
  • It's also often easy to remove content from sites you don't own if you put it there, such as photos you've uploaded, or content on your profile page.
  • If you can't remove something yourself, you can contact the site's webmaster and ask them to remove the content or the page in question.
After you or the site's webmaster has removed or edited the page, you can expedite the removal of that content from Google using our URL removal tool.

Proactively publish information

Sometimes, however, you may not be able to get in touch with a site's webmaster, or they may refuse to take down the content in question. For example, if someone posts a negative review of your business on a restaurant review or consumer complaint site, that site might not be willing to remove the review. If you can't get the content removed from the original site, you probably won't be able to completely remove it from Google's search results, either. Instead, you can try to reduce its visibility in the search results by proactively publishing useful, positive information about yourself or your business. If you can get stuff that you want people to see to outperform the stuff you don't want them to see, you'll be able to reduce the amount of harm that that negative or embarrassing content can do to your reputation.

You can publish or encourage positive content in a variety of ways:
  • Create a Google profile. When people search for your name, Google can display a link to your Google profile in our search results and people can click through to see whatever information you choose to publish in your profile.
  • If a customer writes a negative review of your business, you could ask some of your other customers who are happy with your company to give a fuller picture of your business.
  • If a blogger is publishing unflattering photos of you, take some pictures you prefer and publish them in a blog post or two.
  • If a newspaper wrote an article about a court case that put you in a negative light, but which was subsequently ruled in your favor, you can ask them to update the article or publish a follow-up article about your exoneration. (This last one may seem far-fetched, but believe it or not, we've gotten multiple requests from people in this situation.)
Hope these tips have been helpful! Feel free to stop by our Web Search Forum and share your own advice or stories about how you manage your reputation online.

from web contents: Using schema.org markup for organization logos 2013

salam every one, this is a topic from google web master centrale blog:
Webmaster level: all

Today, we’re launching support for the schema.org markup for organization logos, a way to connect your site with an iconic image. We want you to be able to specify which image we use as your logo in Google search results.

Using schema.org Organization markup, you can indicate to our algorithms the location of your preferred logo. For example, a business whose homepage is www.example.com can add the following markup using visible on-page elements on their homepage:

<div itemscope itemtype="http://schema.org/Organization">
<a itemprop="url" href="http://www.example.com/">Home</a>
<img itemprop="logo" src="http://www.example.com/logo.png" />
</div>

This example indicates to Google that this image is designated as the organization’s logo image for the homepage also included in the markup, and, where possible, may be used in Google search results. Markup like this is a strong signal to our algorithms to show this image in preference over others, for example when we show Knowledge Graph on the right hand side based on users’ queries.

As always, please ask us in the Webmaster Help Forum if you have any questions.

from web contents: View-all in search results 2013

salam every one, this is a topic from google web master centrale blog: Webmaster level: Intermediate to Advanced

User testing has taught us that searchers much prefer the view-all, single-page version of content over a component page containing only a portion of the same information with arbitrary page breaks (which cause the user to click “next” and load another URL).


Searchers often prefer the view-all vs. paginated content with arbitrary page breaks and worse latency.

Therefore, to improve the user experience, when we detect that a content series (e.g. page-1.html, page-2.html, etc.) also contains a single-page version (e.g. page-all.html), we’re now making a larger effort to return the single-page version in search results. If your site has a view-all option, there’s nothing you need to do; we’ll work to do it on your behalf. Also, indexing properties, like links, will be consolidated from the component pages in the series to the view-all page.

However, high latency can make the view-all less preferred

Interestingly, the cases when users didn’t prefer the view-all page were correlated with high latency (e.g., when the view-all page took a while to load, say, because it contained many images). This makes sense because we know users are less satisfied with slow results. So while a view-all page is commonly desired, as a webmaster it’s important to balance this preference with the page’s load time and overall user experience.

Best practices for a series of content
  1. If your site includes view-all pages

    We aim to detect the view-all version of your content and, if available, its associated component pages. There’s nothing more you need to do! However, if you’d like to make it more explicit to us, you can include rel=”canonical” from your component pages to your view-all to increase the likelihood that we detect your series of pages appropriately.


    rel=”canonical” can specify the superset of content (i.e. the view-all page, in this case page-all.html) from the same information in a series of URLs.

    Why does this work?

    In the diagram, page-2.html of a series may specify the canonical target as page-all.html because page-all.html is a superset of page-2.html's content. When a user searches for a query term and page-all.html is selected in search results, even if the query most related to page-2.html, we know the user will still see page-2.html’s relevant information within page-all.html.


    On the other hand, page-2.html shouldn’t designate page-1.html as the canonical because page-2.html’s content isn’t included on page-1.html. It’s possible that a user’s search query is relevant to content on page-2.html, but if page-2.html’s canonical is set to page-1.html, the user could then select page-1.html in search results and find herself in a position where she has to further navigate to a different page to arrive at the desired information. That’s a poor experience for the user, a suboptimal result from us, and it could also bring poorly targeted traffic to your site.


    However, if you strongly desire your view-all page not to appear in search results: 1) make sure the component pages in the series don’t include rel=”canonical” to the view-all page, and 2) mark the view-all page as “noindex” using any of the standard methods.
  2. If you’d like to surface individual, component pages (or there’s no view-all available)

    It may be the case that one or both of the situations below apply to your site:

    • The view-all page is undesirable as a search result (e.g., load time too high or too difficult for users to navigate).
    • Your users prefer the multi-page experience and to be directed to a component page in search results, rather than the view-all page.

    If so, you can use standard HTML rel=”next” and rel=”prev” elements to specify a relationship between the component pages in your series of content. If done correctly, Google will generally strive to:

    • Consolidate indexing properties, such as links, between the component pages/URLs.
    • Send users to the most relevant page/URL from the component pages. Typically, the most relevant page is the first page of your content, but our algorithms may point users to one of the component pages in the series.

It’s not uncommon for webmasters to incorrectly use rel=”canonical” from component pages to the first page of their series (e.g. page-2.html with rel=”canonical” to page-1.html). We recommend against this implementation because the component pages don’t actually contain duplicate content. Using rel=”next” and rel=”prev” is far more appropriate.

Summary

Because users generally prefer the view-all option in search results, we’re making more of an effort to properly detect and serve this version to searchers. If you have a series of content, there’s nothing more you need to do. If you’d like to hint more to Google how best to serve users your information:
  1. To better optimize your view-all page, you can use rel=”canonical” from component pages to the single-page version; otherwise,
  2. If a view-all page doesn’t provide a good user experience for your site, you can use the rel=”next” and rel=”prev” attributes as a strong hint for Google to identify the series of pages and still surface a component page in results.

Questions?

As always, feel free to ask in our Webmaster Help Forum.

from web contents: Pagination with rel=“next” and rel=“prev” 2013

salam every one, this is a topic from google web master centrale blog: Webmaster level: Intermediate to Advanced

Much like rel=”canonical” acts a strong hint for duplicate content, you can now use the HTML link elements rel=”next” and rel=”prev” to indicate the relationship between component URLs in a paginated series. Throughout the web, a paginated series of content may take many shapes—it can be an article divided into several component pages, or a product category with items spread across several pages, or a forum thread divided into a sequence of URLs. Now, if you choose to include rel=”next” and rel=”prev” markup on the component pages within a series, you’re giving Google a strong hint that you’d like us to:
  • Consolidate indexing properties, such as links, from the component pages/URLs to the series as a whole (i.e., links should not remain dispersed between page-1.html, page-2.html, etc., but be grouped with the sequence).
  • Send users to the most relevant page/URL—typically the first page of the series.


The relationship between component URLs in a series can now be indicated to Google through rel=”next” and rel=”prev”.

There’s an exception to the rel=”prev” and rel=”next” implementation: If, alongside your series of content, you also offer users a view-all page, or if you’re considering a view-all page, please see our post on View-all in search results for more information. Because view-all pages are most commonly preferred by searchers, we do our best to surface this version when appropriate in results rather than a component page (component pages are more likely to surface with rel=”next” and rel=”prev”).

If you don’t have a view-all page or you’d like to override Google returning a view-all page, you can use rel="next" and rel="prev" as described in this post.

For information on paginated configurations that include a view-all page, please see our post on View-all in search results.

Outlining your options

Here are three options for a series:
  1. Leave whatever you have exactly as-is. Paginated content exists throughout the web and we’ll continue to strive to give searchers the best result, regardless of the page’s rel=”next”/rel=”prev” HTML markup—or lack thereof.
  2. If you have a view-all page, or are considering a view-all page, see our post on View-all in search results.
  3. Hint to Google the relationship between the component URLs of your series with rel=”next” and rel=”prev”. This helps us more accurately index your content and serve to users the most relevant page (commonly the first page). Implementation details below.

Implementing rel=”next” and rel=”prev”

If you prefer option 3 (above) for your site, let’s get started! Let’s say you have content paginated into the URLs:

http://www.example.com/article?story=abc&page=1
http://www.example.com/article?story=abc&page=2
http://www.example.com/article?story=abc&page=3
http://www.example.com/article?story=abc&page=4

On the first page, http://www.example.com/article?story=abc&page=1, you’d include in the <head> section:
<link rel="next" href="http://www.example.com/article?story=abc&page=2" />

On the second page, http://www.example.com/article?story=abc&page=2:
<link rel="prev" href="http://www.example.com/article?story=abc&page=1" />
<link rel="next" href="http://www.example.com/article?story=abc&page=3" />

On the third page, http://www.example.com/article?story=abc&page=3:
<link rel="prev" href="http://www.example.com/article?story=abc&page=2" />
<link rel="next" href="http://www.example.com/article?story=abc&page=4" />

And on the last page, http://www.example.com/article?story=abc&page=4:
<link rel="prev" href="http://www.example.com/article?story=abc&page=3" />

A few points to mention:
  • The first page only contains rel=”next” and no rel=”prev” markup.
  • Pages two to the second-to-last page should be doubly-linked with both rel=”next” and rel=”prev” markup.
  • The last page only contains markup for rel=”prev”, not rel=”next”.
  • rel=”next” and rel=”prev” values can be either relative or absolute URLs (as allowed by the <link> tag). And, if you include a <base> link in your document, relative paths will resolve according to the base URL.
  • rel=”next” and rel=”prev” only need to be declared within the <head> section, not within the document <body>.
  • We allow rel=”previous” as a syntactic variant of rel=”prev” links.
  • rel="next" and rel="previous" on the one hand and rel="canonical" on the other constitute independent concepts. Both declarations can be included in the same page. For example, http://www.example.com/article?story=abc&page=2&sessionid=123 may contain:

    <link rel="canonical" href="http://www.example.com/article?story=abc&page=2”/>
    <link rel="prev" href="http://www.example.com/article?story=abc&page=1&sessionid=123" />
    <link rel="next" href="http://www.example.com/article?story=abc&page=3&sessionid=123" />

  • rel=”prev” and rel=”next” act as hints to Google, not absolute directives.
  • When implemented incorrectly, such as omitting an expected rel="prev" or rel="next" designation in the series, we'll continue to index the page(s), and rely on our own heuristics to understand your content.

from web contents: Announcing Instant Pages 2013

salam every one, this is a topic from google web master centrale blog: Webmaster level: All

Earlier today we announced Instant Pages, a new feature to help users get to their desired search results even faster--in some cases even instantly! The Instant Pages feature is enabled by prerendering technology that we are building into Chrome and then is intelligently triggered by web search when we're very confident about which result is the best answer for the user's search.

This prerendering technology is currently in the Chrome Dev Channel and will be going to Beta later this week.

You can see Instant Pages in action in this video:


At Google we're obsessed with speed. We've seen time and time again how an increase in apparent speed leads to a direct increase in user happiness and engagement. Instant Pages helps visitors arrive at your site faster. When we trigger Instant Pages for your site, users can start interacting with your site almost immediately, without having to wait for text and images to load. We'll only trigger Instant Pages when we have very high confidence that your site is the exact result users are looking for. Search traffic will be measured in Webmaster Tools just like before this feature, with only results the user visited counted. We'll take the time this summer before the feature launches in stable versions of Chrome to collect your feedback.

The vast majority of sites will automatically work correctly when prerendered in Chrome. Check out the prerendering post on the Chromium blog if you want to learn more about how prerendering works in Chrome or how you can detect that your site is being prerendered.

from web contents: Better recipes on the web: Introducing recipe rich snippets 2013

salam every one, this is a topic from google web master centrale blog: Webmaster Level: All

Anticipating the start of the season of barbecues and potlucks, we’ve added recipes as our newest rich snippets format. This means that for certain sites with recipe content, Google users will see quick facts when these recipe pages show up as part of the search results.

For example, if you were searching for an easy to make thai mango salad, you can now see user ratings, preparation time, and a picture of the dish directly in search result snippets.


Recipes is the fifth format we support, following the introduction of reviews, people, video and, most recently, events.

If you have recipe content on your site, you can get started now by marking up your recipes with microdata, RDFa, or the hRecipe microformat. To learn more, read our documentation on how to mark up recipe information or our general help articles on rich snippets for a more complete overview.

Please remember that to ensure a great user experience we’re taking a gradual approach to surface rich snippets. This means that we can’t guarantee that marking up your site will result in a rich snippet when your page shows up on our search results. However, we encourage you to get started, and once you’re done you can test your pages with our rich snippets testing tool.

from web contents: Video about pagination with rel=“next” and rel=“prev” 2013

salam every one, this is a topic from google web master centrale blog: Webmaster Level: Beginner to Intermediate

If you’re curious about the rel=”next” and rel=prev” for paginated content announcement we made several months ago, we filmed a video covering more of the basics of pagination to help answer your questions. Paginated content includes things like an article that spans several URLs/pages, or an e-commerce product category that spans multiple pages. With rel=”next” and rel=”prev” markup, you can provide a strong hint to Google that you would like us to treat these pages as a logical sequence, thus consolidating their linking properties and usually sending searchers to the first page. Feel free to check out our presentation for more information:


This video on pagination covers the basics of rel=”next” and rel=”prev” and how it could be useful for your site.


Slides from the pagination video

Additional resources about pagination include:
  • Webmaster Central Blog post announcing support of rel=”next” and rel=”prev”
  • Webmaster Help Center article with more implementations of rel=”next” and rel=”prev
  • Webmaster Forum thread with our answers to the community’s in-depth questions, such as:

    Does rel=next/prev also work as a signal for only one page of the series (page 1 in most cases?) to be included in the search index? Or would noindex tags need to be present on page 2 and on?

    When you implement rel="next" and rel="prev" on component pages of a series, we'll then consolidate the indexing properties from the component pages and attempt to direct users to the most relevant page/URL. This is typically the first page. There's no need to mark page 2 to n of the series with noindex unless you're sure that you don't want those pages to appear in search results.

    Should I use the rel next/prev into [sic] the section of a blog even if the two contents are not strictly correlated (but they are just time-sequential)?

    In regard to using rel=”next” and rel=”prev” for entries in your blog that “are not strictly correlated (but they are just time-sequential),” pagination markup likely isn’t the best use of your time -- time-sequential pages aren’t nearly as helpful to our indexing process as semantically related content, such as pagination on component pages in an article or category. It’s fine if you include the markup on your time-sequential pages, but please note that it’s not the most helpful use case.

    We operate a real estate rental website. Our files display results based on numerous parameters that affect the order and the specific results that display. Examples of such parameters are “page number”, “records per page”, “sorting” and “area selection”...

    It sounds like your real estate rental site encounters many of the same issues that e-commerce sites face... Here are some ideas on your situation:

    1. It’s great that you are using the Webmaster Tools URL parameters feature to more efficiently crawl your site.

    2. It’s possible that your site can form a rel=”next” and rel=”prev” sequence with no parameters (or with default parameter values). It’s also possible to form parallel pagination sequences when users select certain parameters, such as a sequence of pages where there are 15 records and a separate sequence when a user selects 30 records. Paginating component pages, even with parameters, helps us more accurately index your content.

    3. While it’s fine to set rel=”canonical” from a component URL to a single view-all page, setting the canonical to the first page of a parameter-less sequence is considered improper usage. We make no promises to honor this implementation of rel=”canonical.”

Remember that if you have paginated content, it’s fine to leave it as-is and not add rel=”next” and rel=”prev” markup at all. But if you’re interested in pagination markup as a strong hint for us to better understand your site, we hope these resources help answer your questions!

from web contents: Specify your canonical 2013

salam every one, this is a topic from google web master centrale blog:
Carpe diem on any duplicate content worries: we now support a format that allows you to publicly specify your preferred version of a URL. If your site has identical or vastly similar content that's accessible through multiple URLs, this format provides you with more control over the URL returned in search results. It also helps to make sure that properties such as link popularity are consolidated to your preferred version.

Let's take our old example of a site selling Swedish fish. Imagine that your preferred version of the URL and its content looks like this:

http://www.example.com/product.php?item=swedish-fish


However, users (and Googlebot) can access Swedish fish through multiple (not as simple) URLs. Even if the key information on these URLs is the same as your preferred version, they may show slight content variations due to things like sort parameters or category navigation:

http://www.example.com/product.php?item=swedish-fish&category=gummy-candy

Or they have completely identical content, but with different URLs due to things such as a tracking parameters or a session ID:

http://www.example.com/product.php?item=swedish-fish&trackingid=1234&sessionid=5678

Now, you can simply add this <link> tag to specify your preferred version:

<link rel="canonical" href="http://www.example.com/product.php?item=swedish-fish" />

inside the <head> section of the duplicate content URLs:

http://www.example.com/product.php?item=swedish-fish&category=gummy-candy
http://www.example.com/product.php?item=swedish-fish&trackingid=1234&sessionid=5678


and Google will understand that the duplicates all refer to the canonical URL: http://www.example.com/product.php?item=swedish-fish. Additional URL properties, like PageRank and related signals, are transferred as well.

This standard can be adopted by any search engine when crawling and indexing your site.

Of course you may have more questions. Joachim Kupke, an engineer from our Indexing Team, is here to provide us with the answers:

Is rel="canonical" a hint or a directive?
It's a hint that we honor strongly. We'll take your preference into account, in conjunction with other signals, when calculating the most relevant page to display in search results.

Can I use a relative path to specify the canonical, such as <link rel="canonical" href="product.php?item=swedish-fish" />?
Yes, relative paths are recognized as expected with the <link> tag. Also, if you include a <base> link in your document, relative paths will resolve according to the base URL.

Is it okay if the canonical is not an exact duplicate of the content?
We allow slight differences, e.g., in the sort order of a table of products. We also recognize that we may crawl the canonical and the duplicate pages at different points in time, so we may occasionally see different versions of your content. All of that is okay with us.

What if the rel="canonical" returns a 404?
We'll continue to index your content and use a heuristic to find a canonical, but we recommend that you specify existent URLs as canonicals.

What if the rel="canonical" hasn't yet been indexed?
Like all public content on the web, we strive to discover and crawl a designated canonical URL quickly. As soon as we index it, we'll immediately reconsider the rel="canonical" hint.

Can rel="canonical" be a redirect?
Yes, you can specify a URL that redirects as a canonical URL. Google will then process the redirect as usual and try to index it.

What if I have contradictory rel="canonical" designations?
Our algorithm is lenient: We can follow canonical chains, but we strongly recommend that you update links to point to a single canonical page to ensure optimal canonicalization results.

Can this link tag be used to suggest a canonical URL on a completely different domain?
**Update on 12/17/2009: The answer is yes! We now support a cross-domain rel="canonical" link element.**

Previous answer below:
No. To migrate to a completely different domain, permanent (301) redirects are more appropriate. Google currently will take canonicalization suggestions into account across subdomains (or within a domain), but not across domains. So site owners can suggest www.example.com vs. example.com vs. help.example.com, but not example.com vs. example-widgets.com.

Sounds great—can I see a live example?
Yes, wikia.com helped us as a trusted tester. For example, you'll notice that the source code on the URL http://starwars.wikia.com/wiki/Nelvana_Limited specifies its rel="canonical" as: http://starwars.wikia.com/wiki/Nelvana.

The two URLs are nearly identical to each other, except that Nelvana_Limited, the first URL, contains a brief message near its heading. It's a good example of using this feature. With rel="canonical", properties of the two URLs are consolidated in our index and search results display wikia.com's intended version.

Feel free to ask additional questions in our comments below. And if you're unable to implement a canonical designation link, no worries; we'll still do our best to select a preferred version of your duplicate content URLs, and transfer linking properties, just as we did before.

Update: this link-tag is currently also supported by Ask.com, Microsoft Live Search and Yahoo!.

Update: for more information, please see our Help Center articles on canonicalization and rel=canonical.

from web contents: Google's SEO Starter Guide 2013

salam every one, this is a topic from google web master centrale blog:

Note: The SEO Starter Guide has since been updated.

Webmasters often ask us at conferences or in the Webmaster Help Group, "What are some simple ways that I can improve my website's performance in Google?" There are lots of possible answers to this question, and a wealth of search engine optimization information on the web, so much that it can be intimidating for newer webmasters or those unfamiliar with the topic. We thought it'd be useful to create a compact guide that lists some best practices that teams within Google and external webmasters alike can follow that could improve their sites' crawlability and indexing.

Our Search Engine Optimization Starter Guide covers around a dozen common areas that webmasters might consider optimizing. We felt that these areas (like improving title and description meta tags, URL structure, site navigation, content creation, anchor text, and more) would apply to webmasters of all experience levels and sites of all sizes and types. Throughout the guide, we also worked in many illustrations, pitfalls to avoid, and links to other resources that help expand our explanation of the topics. We plan on updating the guide at regular intervals with new optimization suggestions and to keep the technical advice current.

So, the next time we get the question, "I'm new to SEO, how do I improve my site?", we can say, "Well, here's a list of best practices that we use inside Google that you might want to check out."

Update on July 22, 2009: The SEO Starter Guide is now available in 40 languages!

from web contents: Introducing Rich Snippets 2013

salam every one, this is a topic from google web master centrale blog:
Webmaster Level: All

As a webmaster, you have a unique understanding of your web pages and the content they represent. Google helps users find your page by showing them a small sample of that content -- the "snippet." We use a variety of techniques to create these snippets and give users relevant information about what they'll find when they click through to visit your site. Today, we're announcing Rich Snippets, a new presentation of snippets that applies Google's algorithms to highlight structured data embedded in web pages.


Rich Snippets give users convenient summary information about their search results at a glance. We are currently supporting data about reviews and people. When searching for a product or service, users can easily see reviews and ratings, and when searching for a person, they'll get help distinguishing between people with the same name. It's a simple change to the display of search results, yet our experiments have shown that users find the new data valuable -- if they see useful and relevant information from the page, they are more likely to click through. Now we're beginning the process of opening up this successful experiment so that more websites can participate. As a webmaster, you can help by annotating your pages with structured data in a standard format.

To display Rich Snippets, Google looks for markup formats (microformats and RDFa) that you can easily add to your own web pages. In most cases, it's as quick as wrapping the existing data on your web pages with some additional tags. For example, here are a few relevant lines of the HTML from Yelp's review page for "Drooling Dog BarBQ" before adding markup data:


and now with microformats markup:


or alternatively, use RDFa markup. Either format works:


By incorporating standard annotations in your pages, you not only make your structured data available for Google's search results, but also for any service or tool that supports the same standard. As structured data becomes more widespread on the web, we expect to find many new applications for it, and we're excited about the possibilities.

To ensure that this additional data is as helpful as possible to users, we'll be rolling this feature out gradually, expanding coverage to more sites as we do more experiments and process feedback from webmasters. We will make our best efforts to monitor and analyze whether individual websites are abusing this system: if we see abuse, we will respond accordingly.

To prepare your site for Rich Snippets and other benefits of structured data on the web, please see our documentation on structured data annotations.

Now, time for some Q&A with the team:

If I mark up my pages, does that guarantee I'll get Rich Snippets?

No. We will be rolling this out gradually, and as always we will use our own algorithms and policies to determine relevant snippets for users' queries. We will use structured data when we are able to determine that it helps users find answers sooner. And because you're providing the data on your pages, you should anticipate that other websites and other tools (browsers, phones) might use this data as well. You can let us know that you're interested in participating by filling out this form.

What about other existing microformats? Will you support other types of information besides reviews and people?

Not every microformat corresponds to data that's useful to show in a search result, but we do plan to support more of the existing microformats and define RDFa equivalents.

What's next?

We'll be continuing experiments with new types (beyond reviews and people) and hope to announce support for more types in the future.

I have too much data on my page to mark it all up.

That wasn't a question, but we'll answer anyway. For the purpose of getting data into snippets, we don't need every bit of data: it simply wouldn't fit. For example, a page that says it has "497 reviews" of a product probably has data for 10 and links to the others. Even if you could mark up all 497 blocks of data, there is no way we could fit it into a single snippet. To make your part of this grand experiment easier, we have defined aggregate types where necessary: a review-aggregate can be used to summarize all the review information (review count, average/min/max rating, etc.).

Why do you support multiple encodings?

A lot of previous work on structured data has focused on debates around encoding. Even within Google, we have advocates for microformat encoding, advocates for various RDF encodings, and advocates for our own encodings. But after working on this Rich Snippets project for a while, we realized that structured data on the web can and should accommodate multiple encodings: we hope to emphasize this by accepting both microformat encoding and RDFa encoding. Each encoding has its pluses and minuses, and the debate is a fine intellectual exercise, but it detracts from the real issues.

We do believe that it is important to have a common vocabulary: the language of object types, object properties, and property types that enable structured data to be understood by different applications. We debated how to address this vocabulary problem, and concluded that we needed to make an investment. Google will, working together with others, host a vocabulary that various Google services and other websites can use. We are starting with a small list, which we hope to extend over time.

Wherever possible, we'll simply reuse vocabulary that is in wide use: we support the pre-existing vCard and hReview types, and there are a variety of other types defined by various communities. Sites that use Google Custom Search will be able to define their own types, which we will index and present to users in rich Custom Search results pages. Finally, we encourage and expect this space to evolve based on new ideas from the structured data community. We'll notice and reach out when our crawlers pick up new types that are getting broad use.

Update on November 1, 2009: Check out our update on Rich Snippets!

from web contents: Introducing Data Highlighter for event data 2013

salam every one, this is a topic from google web master centrale blog: Webmaster Level: All

Update 19 February 2013: Data Highlighter for events structured markup is available in all languages in Webmaster Tools.

At Google we're making more and more use of structured data to provide enhanced search results, such as rich snippets and event calendars, that help users find your content. Until now, marking up your site's HTML code has been the only way to indicate structured data to Google. However, we recognize that markup may be hard for some websites to deploy.

Today, we're offering webmasters a simpler alternative: Data Highlighter. At initial launch, it's available in English only and for structured data about events, such as concerts, sporting events, exhibitions, shows, and festivals. We'll make Data Highlighter available for more languages and data types in the months ahead. Update 19 February 2013: Data Highlighter for events structured markup is available in all languages in Webmaster Tools.

Data Highlighter is a point-and-click tool that can be used by anyone authorized for your site in Google Webmaster Tools. No changes to HTML code are required. Instead, you just use your mouse to highlight and "tag" each key piece of data on a typical event page of your website:
Events markup with Data Highlighter

If your page lists multiple events in a consistent format, Data Highlighter will "learn" that format as you apply tags, and help speed your work by automatically suggesting additional tags. Likewise, if you have many pages of events in a consistent format, Data Highlighter will walk you through a process of tagging a few example pages so it can learn about their format variations. Usually, 5 or 10 manually tagged pages are enough for our sophisticated machine-learning algorithms to understand the other, similar pages on your site.

When you're done, you can review a sample of all the event data that Data Highlighter now understands. If it's correct, click "Publish."
From then on, as Google crawls your site, it will recognize your latest event listings and make them eligible for enhanced search results. You can inspect the crawled data on the Structured Data Dashboard, and unpublish at any time if you're not happy with the results.

Here’s a short video explaining how the process works:

To get started with Data Highlighter, visit Webmaster Tools, select your site, click the "Optimization" link in the left sidebar, and click "Data Highlighter".

If you have any questions, please read our Help Center article or ask us in the Webmaster Help Forum. Happy Highlighting!

from web contents: Better page titles in search results 2013

salam every one, this is a topic from google web master centrale blog:

Page titles are an important part of our search results: they’re the first line of each result and they’re the actual links our searchers click to reach websites. Our advice to webmasters has always been to write unique, descriptive page titles (and meta descriptions for the snippets) to describe to searchers what the page is about.

We use many signals to decide which title to show to users, primarily the <title> tag if the webmaster specified one. But for some pages, a single title might not be the best one to show for all queries, and so we have algorithms that generate alternative titles to make it easier for our users to recognize relevant pages. Our testing has shown that these alternative titles are generally more relevant to the query and can substantially improve the clickthrough rate to the result, helping both our searchers and webmasters. About half of the time, this is the reason we show an alternative title.

Other times, alternative titles are displayed for pages that have no title or a non-descriptive title specified by the webmaster in the HTML. For example, a title using simply the word "Home" is not really indicative of what the page is about. Another common issue we see is when a webmaster uses the same title on almost all of a website’s pages, sometimes exactly duplicating it and sometimes using only minor variations. Lastly, we also try to replace unnecessarily long or hard-to-read titles with more concise and descriptive alternatives.

For more information about how you can write better titles and meta descriptions, and to learn more about the signals we use to generate alternative titles, we've recently updated the Help Center article on this topic. Also, we try to notify webmasters when we discover titles that can be improved on their websites through the HTML Suggestions feature in Webmaster Tools; you can find this feature in the Diagnostics section of the menu on the left hand side.

As always, if you have any questions or feedback, please tell us in the Webmaster Help Forum.
