salam every one, this is a topic from google web master centrale blog: Written by Michael Wyszomierski and Greg Grothaus, Search Quality

Update on July 29, 2010: We've improved our Flash indexing capability and we also now support an AJAX crawling scheme! Please check out the posts (linked above) for more details.

Many webmasters have discovered the advantages of using Ajax to improve the user experience on their sites, creating dynamic pages that act as powerful web applications. But, like Flash, Ajax can make a site difficult for search engines to index if the technology is not implemented carefully. As promised in our post answering questions about Server location, cross-linking, and Web 2.0 technology, we've compiled some tips for creating Ajax-enhanced websites that are also understood by search engines.

How will Google see my site?

One of the main issues with Ajax sites is that while Googlebot is great at following and understanding the structure of HTML links, it can have a difficult time finding its way around sites which use JavaScript for navigation. While we are working to better understand JavaScript, your best bet for creating a site that's crawlable by Google and other search engines is to provide HTML links to your content.

Design for accessibility

We encourage webmasters to create pages for users, not just search engines. When you're designing your Ajax site, think about the needs of your users, including those who may not be using a JavaScript-capable browser. There are plenty of such users on the web, including those using screen readers or mobile devices.

One of the easiest ways to test your site's accessibility to this type of user is to explore the site in your browser with JavaScript turned off, or by viewing it in a text-only browser such as Lynx. Viewing a site as text-only can also help you identify other content which may be hard for Googlebot to see, including images and Flash.

Develop with progressive enhancement

If you're starting from scratch, one good approach is to build your site's structure and navigation using only HTML. Then, once you have the site's pages, links, and content in place, you can spice up the appearance and interface with Ajax. Googlebot will be happy looking at the HTML, while users with modern browsers can enjoy your Ajax bonuses.

Of course you will likely have links requiring JavaScript for Ajax functionality, so here's a way to help Ajax and static links coexist:
When creating your links, format them so they'll offer a static link as well as calling a JavaScript function. That way you'll have the Ajax functionality for JavaScript users, while non-JavaScript users can ignore the script and follow the link. For example:


Note that the static link's URL has a parameter (?foo=32) instead of a fragment (#foo=32), which is used by the Ajax code. This is important, as search engines understand URL parameters but often ignore fragments. Web developer Jeremy Keith labeled this technique as Hijax. Since you now offer static links, users and search engines can link to the exact content they want to share or reference.

While we're constantly improving our crawling capability, using HTML links remains a strong way to help us (as well as other search engines, mobile devices and users) better understand your site's structure.

Follow the guidelines

In addition to the tips described here, we encourage you to also check out our Webmaster Guidelines for more information about what can make a site good for Google and your users. The guidelines also point out some practices to avoid, including sneaky JavaScript redirects. A general rule to follow is that while you can provide users different experiences based on their capabilities, the content should remain the same. For example, imagine we've created a page for Wysz's Hamster Farm. The top of the page has a heading of "Wysz's Hamster Farm," and below it is an Ajax-powered slideshow of the latest hamster arrivals. Turning JavaScript off on the same page shouldn't surprise a user with additional text reading:

Wysz's Hamster Farm -- hamsters, best hamsters, cheap hamsters, free hamsters, pets, farms, hamster farmers, dancing hamsters, rodents, hampsters, hamsers, best hamster resource, pet toys, dancing lessons, cute, hamster tricks, pet food, hamster habitat, hamster hotels, hamster birthday gift ideas and more!

A more ideal implementation would display the same text whether JavaScript was enabled or not, and in the best scenario, offer an HTML version of the slideshow to non-JavaScript users.

This is a pretty advanced topic, so please continue the discussion by asking questions and sharing ideas over in the Webmaster Help Group. See you there!this is a topic published in 2013... to get contents for your blog or your forum, just contact me at: devnasser@gmail.com

salam every one, this is a topic from google web master centrale blog: Handling duplicate content within your own website can be a big challenge. Websites grow; features get added, changed and removed; content comes—content goes. Over time, many websites collect systematic cruft in the form of multiple URLs that return the same contents. Having duplicate content on your website is generally not problematic, though it can make it harder for search engines to crawl and index the content. Also, PageRank and similar information found via incoming links can get diffused across pages we aren't currently recognizing as duplicates, potentially making your preferred version of the page rank lower in Google.

Steps for dealing with duplicate content within your website

1. Recognize duplicate content on your website.
   The first and most important step is to recognize duplicate content on your website. A simple way to do this is to take a unique text snippet from a page and to search for it, limiting the results to pages from your own website by using a site:query in Google. Multiple results for the same content show duplication you can investigate.
   
2. Determine your preferred URLs.
   Before fixing duplicate content issues, you'll have to determine your preferred URL structure. Which URL would you prefer to use for that piece of content?
   
3. Be consistent within your website.
   Once you've chosen your preferred URLs, make sure to use them in all possible locations within your website (including in your Sitemap file).
   
4. Apply 301 permanent redirects where necessary and possible.
   If you can, redirect duplicate URLs to your preferred URLs using a 301 response code. This helps users and search engines find your preferred URLs should they visit the duplicate URLs. If your site is available on several domain names, pick one and use the 301 redirect appropriately from the others, making sure to forward to the right specific page, not just the root of the domain. If you support both www and non-www host names, pick one, use the preferred domain setting in Webmaster Tools, and redirect appropriately.
   
5. Implement the rel="canonical" link element on your pages where you can.
   Where 301 redirects are not possible, the rel="canonical" link element can give us a better understanding of your site and of your preferred URLs. The use of this link element is also supported by major search engines such as Ask.com, Bing and Yahoo!.
   
6. Use the URL parameter handling tool in Google Webmaster Tools where possible.
   If some or all of your website's duplicate content comes from URLs with query parameters, this tool can help you to notify us of important and irrelevant parameters within your URLs. More information about this tool can be found in our announcement blog post.
   

What about the robots.txt file?

One item which is missing from this list is disallowing crawling of duplicate content with your robots.txt file. We now recommend not blocking access to duplicate content on your website, whether with a robots.txt file or other methods. Instead, use the rel="canonical" link element, the URL parameter handling tool, or 301 redirects. If access to duplicate content is entirely blocked, search engines effectively have to treat those URLs as separate, unique pages since they cannot know that they're actually just different URLs for the same content. A better solution is to allow them to be crawled, but clearly mark them as duplicate using one of our recommended methods. If you allow us to crawl these URLs, Googlebot will learn rules to identify duplicates just by looking at the URL and should largely avoid unnecessary recrawls in any case. In cases where duplicate content still leads to us crawling too much of your website, you can also adjust the crawl rate setting in Webmaster Tools.

We hope these methods will help you to master the duplicate content on your website! Information about duplicate content in general can also be found in our Help Center. Should you have any questions, feel free to join the discussion in our Webmaster Help Forum.

Seo Master present to you: By Ben Collins-Sussman, Open Source Team

If you have open source projects hosted on Google Code, you may have noticed that the SSL certificate changed for the googlecode.com domain. (The old certificate expired, and a new one was generated.) In particular, your Subversion client may have yelled about the certificate not being recognized:

Error validating server certificate for
'https://projectname.googlecode.com:443':
- The certificate is not issued by a trusted authority. Use the
 fingerprint to validate the certificate manually!
Certificate information:
- Hostname: googlecode.com
- Valid: from Wed, 28 May 2008 16:48:13 GMT until Mon, 21 Jun 2010 14:09:43 GMT
- Issuer: Certification Services Division, Thawte Consulting cc, Cape
Town, Western Cape, ZA
- Fingerprint: b1:3a:d5:38:56:27:52:9f:ba:6c:70:1e:a9:ab:4a:1a:8b:da:ff:ec
(R)eject, accept (t)emporarily or accept (p)ermanently?

Just like a web browser, your Subversion client needs to know whether or not you trust particular SSL certificates coming from servers. You can verify the certificate using the fingerprint above, or you can choose to permanently accept the certificate, whichever makes you feel most comfortable. To permanently accept the certificate, you can simply choose the (p)ermanent option, and Subversion will trust it forever.

Thawte is a large certifying authority, and it's very likely that the OpenSSL libraries on your computer automatically trust any certificate signed by Thawte. However, if you want your Subversion client to inherit that same level of automatic trust, you'll need to set an option in your ~/.subversion/servers file:

[global]
ssl-trust-default-ca = true

If you set this option, then your client will never bug you again about any certificate signed by the "big" authorities.

We launched Webmaster Central back in August 2006, with a goal of creating a place for you to learn more about Google's crawling and indexing of websites, and to offer tools for submitting sitemaps and other content. Given all of your requests and recommendations, we've also been busy working behind the scenes to roll out exciting new features for Webmaster Tools, like internal/external links data and the Message Center, over the past year.

And so today, we're unveiling a new look on the Webmaster Central landing page at http://www.google.com/webmasters. You'll still find all of the tools and resources you've come to love like our Webmaster Blog and discussion group -- but now, in addition to these, we've added a few more you might enjoy and find useful. We hope that the new layout will make it easier to discover some additional resources that will help you learn even more about how to improve traffic to your site, submit content to Google, and enhance your site's functionality.

Here's a brief look at some of the new additions:





We'd love to get your feedback on the new site. Feel free to comment below, or join our discussion group. this is a topic published in 2013... to get contents for your blog or your forum, just contact me at: devnasser@gmail.com

Since we released the latest version of Top Search Queries in Webmaster Tools we've gotten a bunch of feedback, most of which was overwhelmingly positive. Today, we're happy to bring even more improvements to Top Search Queries that we've implemented as a direct result of your feedback. First of all we've shortened "Top Search Queries" to be just "Search Queries" to better reflect all of the data provided by this feature. In addition to the name change you'll notice that Search Queries has several new updates. As requested by many of you, we're now showing an "Average position" column right on the main Search Queries page. This provides a quick at-a-glance way to see where your site is showing in the search results for specific queries. The other change you'll notice is that we're showing a "Displaying" number for Impressions and Clicks. This number represents a total count of the data displayed in the Search Queries table. The number in bold appearing just above it is a total count of all queries including the "long tail" of queries which are not displayed in the Search Queries table. When the "Displaying" number is not visible, such as when you select a specific country from the "All countries" drop-down menu, then the bold number is the total count of the data displayed in the Search Queries table.



We've also added an Average position column to the Search Queries download.



The other addition we've made to Search Queries is a "Starred" tab. Next to each Query on the Search Queries page there is now a clickable star icon. You can click the star icon for all of the queries that are of most interest to you. All of the queries that you "star" will be consolidated under the Starred tab providing a super easy way to view just the queries you care about.



We hope that this update makes Search Queries even more useful. If you've got feedback or suggestions for Search Queries please let us know in the Webmaster Help Forum.

Free web hosting services can be great! Many of these services have helped to lower costs and technical barriers for webmasters and they continue to enable beginner webmasters to start their adventure on the web. Unfortunately, sometimes these lower barriers (meant to encourage less techy audiences) can attract some dodgy characters like spammers who look for cheap and easy ways to set up dozens or hundreds of sites that add little or no value to the web. When it comes to automatically generated sites, our stance remains the same: if the sites do not add sufficient value, we generally consider them as spam and take appropriate steps to protect our users from exposure to such sites in our natural search results.


If a free hosting service begins to show patterns of spam, we make a strong effort to be granular and tackle only spammy pages or sites. However, in some cases, when the spammers have pretty much taken over the free web hosting service or a large fraction of the service, we may be forced to take more decisive steps to protect our users and remove the entire free web hosting service from our search results. To prevent this from happening, we would like to help owners of free web hosting services by sharing what we think may help you save valuable resources like bandwidth and processing power, and also protect your hosting service from these spammers:

• Publish a clear abuse policy and communicate it to your users, for example during the sign-up process. This step will contribute to transparency on what you consider to be spammy activity.
• In your sign-up form, consider using CAPTCHAs or similar verification tools to only allow human submissions and prevent automated scripts from generating a bunch of sites on your hosting service. While these methods may not be 100% foolproof, they can help to keep a lot of the bad actors out.
• Try to monitor your free hosting service for other spam signals like redirections, large numbers of ad blocks, certain spammy keywords, large sections of escaped JavaScript code, etc. Using the site: operator query or Google Alerts may come in handy if you’re looking for a simple, cost efficient solution.
• Keep a record of signups and try to identify typical spam patterns like form completion time, number of requests sent from the same IP address range, user-agents used during signup, user names or other form-submitted values chosen during signup, etc. Again, these may not always be conclusive.
• Keep an eye on your webserver log files for sudden traffic spikes, especially when a newly-created site is receiving this traffic, and try to identify why you are spending more bandwidth and processing power.
• Try to monitor your free web hosting service for phishing and malware-infected pages. For example, you can use the Google Safe Browsing API to regularly test URLs from your service, or sign up to receive alerts for your AS.
• Come up with a few sanity checks. For example, if you’re running a local Polish free web hosting service, what are the odds of thousands of new and legitimate sites in Japanese being created overnight on your service? There’s a number of tools you may find useful for language detection of newly created sites, for example language detection libraries or the Google Translate API v2.

Last but not least, if you run a free web hosting service be sure to monitor your services for sudden activity spikes that may indicate a spam attack in progress.

For more tips on running a quality hosting service, have a look at our previous post. Lastly, be sure to sign up and verify your site in Google Webmaster Tools so we may be able to notify you when needed or if we see issues.

If you're a webmaster or site owner, you realize the importance of providing high quality search on your site so that users easily find the right information.

We just announced today that AdSense for Search is now powered by Custom Search. Custom Search (a Google-powered search box that you can install on your website in minutes) helps your users quickly find what they're looking for. As a webmaster, Custom Search gives you advanced customization options to improve the accuracy of your site's search results. You can also choose to monetize your traffic with ads tuned to the topic of your site. If you don't want ads, you can use Custom Search Business Edition.



Now, we're also looking to index more of your site's content for inclusion in your Custom Search Engine (CSE) used for search on your site. We figure out what sites and URLs are included in your CSE, and -- if you've provided Sitemaps for the relevant sites -- we use that information to create a more comprehensive experience for your site's visitors. You don't have to do anything specific, besides submitting a Sitemap (via Webmaster Tools) for your site if you haven't already done so. Note that this change will not result in more pages indexed on Google.com and your search rankings on Google.com won't change. However, you will be able to get much better results coverage in your CSE.

Custom Search is built on top of the Google index. This means that all pages that are available on Google.com are also available to your search engine. We're now maintaining a CSE-specific index in addition to the Google.com index for enhancing the performance of search on your site. If you submit a Sitemap, it's likely that we will crawl those pages and include them in the additional index we build.

In order for us to index these additional pages, our crawlers must be able to crawl them. Your Sitemap will also help us identify the URLs that are important. Please ensure you are not blocking us from crawling any pages you want indexed. Improved index coverage is not instantaneous, as it takes some time for the pages to be crawled and indexed.

So what are you waiting for? Submit your Sitemap!this is a topic published in 2013... to get contents for your blog or your forum, just contact me at: devnasser@gmail.com

Here's the second of our video blog posts. Matt Cutts, the head of Google's webspam team, provides some useful tips on how to optimize the images you include on your site, and how simply providing useful, accurate information in your ALT attributes can make your photos and pictures more discoverable on the web. Ms Emmy Cutts also makes an appearance.



Like videos? Hate them? Have a great idea we should cover? Let us know what you think in our Webmaster Help Group.

Update: Some of you have asked about the difference between the "alt" and "title" attributes. According to the W3C recommendations, the "alt" attribute specifies an alternate text for user agents that cannot display images, forms or applets. The "title" attribute is a bit different: it "offers advisory information about the element for which it is set." As the Googlebot does not see the images directly, we generally concentrate on the information provided in the "alt" attribute. Feel free to supplement the "alt" attribute with "title" and other attributes if they provide value to your users!this is a topic published in 2013... to get contents for your blog or your forum, just contact me at: devnasser@gmail.com

Webmaster level: All

In recent months we’ve been especially focused on helping people find high-quality sites in Google’s search results. The “Panda” algorithm change has improved rankings for a large number of high-quality websites, so most of you reading have nothing to be concerned about. However, for the sites that may have been affected by Panda we wanted to provide additional guidance on how Google searches for high-quality sites.

Our advice for publishers continues to be to focus on delivering the best possible user experience on your websites and not to focus too much on what they think are Google’s current ranking algorithms or signals. Some publishers have fixated on our prior Panda algorithm change, but Panda was just one of roughly 500 search improvements we expect to roll out to search this year. In fact, since we launched Panda, we've rolled out over a dozen additional tweaks to our ranking algorithms, and some sites have incorrectly assumed that changes in their rankings were related to Panda. Search is a complicated and evolving art and science, so rather than focusing on specific algorithmic tweaks, we encourage you to focus on delivering the best possible experience for users.

What counts as a high-quality site?

Our site quality algorithms are aimed at helping people find "high-quality" sites by reducing the rankings of low-quality content. The recent "Panda" change tackles the difficult task of algorithmically assessing website quality. Taking a step back, we wanted to explain some of the ideas and research that drive the development of our algorithms.

Below are some questions that one could use to assess the "quality" of a page or an article. These are the kinds of questions we ask ourselves as we write algorithms that attempt to assess site quality. Think of it as our take at encoding what we think our users want.

Of course, we aren't disclosing the actual ranking signals used in our algorithms because we don't want folks to game our search results; but if you want to step into Google's mindset, the questions below provide some guidance on how we've been looking at the issue:

• Would you trust the information presented in this article?
• Is this article written by an expert or enthusiast who knows the topic well, or is it more shallow in nature?
• Does the site have duplicate, overlapping, or redundant articles on the same or similar topics with slightly different keyword variations?
• Would you be comfortable giving your credit card information to this site?
• Does this article have spelling, stylistic, or factual errors?
• Are the topics driven by genuine interests of readers of the site, or does the site generate content by attempting to guess what might rank well in search engines?
• Does the article provide original content or information, original reporting, original research, or original analysis?
• Does the page provide substantial value when compared to other pages in search results?
• How much quality control is done on content?
• Does the article describe both sides of a story?
• Is the site a recognized authority on its topic?
• Is the content mass-produced by or outsourced to a large number of creators, or spread across a large network of sites, so that individual pages or sites don’t get as much attention or care?
• Was the article edited well, or does it appear sloppy or hastily produced?
• For a health related query, would you trust information from this site?
• Would you recognize this site as an authoritative source when mentioned by name?
• Does this article provide a complete or comprehensive description of the topic?
• Does this article contain insightful analysis or interesting information that is beyond obvious?
• Is this the sort of page you’d want to bookmark, share with a friend, or recommend?
• Does this article have an excessive amount of ads that distract from or interfere with the main content?
• Would you expect to see this article in a printed magazine, encyclopedia or book?
• Are the articles short, unsubstantial, or otherwise lacking in helpful specifics?
• Are the pages produced with great care and attention to detail vs. less attention to detail?
• Would users complain when they see pages from this site?

Writing an algorithm to assess page or site quality is a much harder task, but we hope the questions above give some insight into how we try to write algorithms that distinguish higher-quality sites from lower-quality sites.

What you can do

We've been hearing from many of you that you want more guidance on what you can do to improve your rankings on Google, particularly if you think you've been impacted by the Panda update. We encourage you to keep questions like the ones above in mind as you focus on developing high-quality content rather than trying to optimize for any particular Google algorithm.

One other specific piece of guidance we've offered is that low-quality content on some parts of a website can impact the whole site’s rankings, and thus removing low quality pages, merging or improving the content of individual shallow pages into more useful pages, or moving low quality pages to a different domain could eventually help the rankings of your higher-quality content.

We're continuing to work on additional algorithmic iterations to help webmasters operating high-quality sites get more traffic from search. As you continue to improve your sites, rather than focusing on one particular algorithmic tweak, we encourage you to ask yourself the same sorts of questions we ask when looking at the big picture. This way your site will be more likely to rank well for the long-term. In the meantime, if you have feedback, please tell us through our Webmaster Forum. We continue to monitor threads on the forum and pass site info on to the search quality team as we work on future iterations of our ranking algorithms.

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

Webmaster level: All

Every day more and more smartphones get activated and more websites are producing smartphone-optimized content. Since we last talked about how to build mobile-friendly websites, we’ve been working hard on improving Google’s support for smartphone-optimized content. As part of this effort, we launched Googlebot-Mobile for smartphones back in December 2011, which is specifically tasked with identifying such content.

Today we’d like to give you Google’s recommendations for building smartphone-optimized websites and explain how to do so in a way that gives both your desktop- and smartphone-optimized sites the best chance of performing well in Google’s search results.

Recommendations for smartphone-optimized sites

The full details of our recommendation can be found in our new help site, which we now summarize.

When building a website that targets smartphones, Google supports three different configurations:

1. Sites that use responsive web design, i.e. sites that serve all devices on the same set of URLs, with each URL serving the same HTML to all devices and using just CSS to change how the page is rendered on the device. This is Google’s recommended configuration.

2. Sites that dynamically serve all devices on the same set of URLs, but each URL serves different HTML (and CSS) depending on whether the user agent is a desktop or a mobile device.

3. Sites that have a separate mobile and desktop sites.

Responsive web design

Responsive web design is a technique to build web pages that alter how they look using CSS3 media queries. That is, there is one HTML code for the page regardless of the device accessing it, but its presentation changes using CSS media queries to specify which CSS rules apply for the browser displaying the page. You can learn more about responsive web design from this blog post by Google's webmasters and in our recommendations.

Using responsive web design has multiple advantages, including:

• It keeps your desktop and mobile content on a single URL, which is easier for your users to interact with, share, and link to and for Google’s algorithms to assign the indexing properties to your content.

• Google can discover your content more efficiently as we wouldn't need to crawl a page with the different Googlebot user agents to retrieve and index all the content.

Device-specific HTML

However, we appreciate that for many situations it may not be possible or appropriate to use responsive web design. That’s why we support having websites serve equivalent content using different, device-specific, HTML. The device-specific HTML can be served on the same URL (a configuration called dynamic serving) or different URLs (such as www.example.com and m.example.com).

If your website uses a dynamic serving configuration, we strongly recommend using the Vary HTTP header to communicate to caching servers and our algorithms that the content may change for different user agents requesting the page. We also use this as a crawling signal for Googlebot-Mobile. More details are here.

As for the separate mobile site configuration, since there are many ways to do this, our recommendation introduces annotations that communicate to our algorithms that your desktop and mobile pages are equivalent in purpose; that is, the new annotations describe the relationship between the desktop and mobile content as alternatives of each other and should be treated as a single entity with each alternative targeting a specific class of device.

These annotations will help us discover your smartphone-optimized content and help our algorithms understand the structure of your content, giving it the best chance of performing well in our search results.

Conclusion

This blog post is only a brief summary of our recommendation for building smartphone-optimized websites. Please read the full recommendation and see which supported implementation is most suitable for your site and users. And, as always, please ask on our Webmaster Help forums if you have more questions.
