from web contents: Google now indexes SVG 2013
salam every one, this is a topic from google web master centrale blog: Webmaster Level: All
You can now use Google search to find SVG documents. SVG is an open, XML-based format for vector graphics with support for interactive elements. We’re big fans of open standards, and our mission is to organize the world’s information, so indexing SVG is a natural step.
We index SVG content whether it is in a standalone file or embedded directly in HTML. The web is big, so it may take some time before we crawl and index most SVG files, but as of today you may start seeing them in your search results. If you want to see it yourself, try searching for [sitemap site:fastsvg.com] or [HideShow site:svg-whiz.com]
If you host SVG files and you wish to exclude them from Google’s search results, you can use the “X-Robots-Tag: noindex” directive in the HTTP header.
Check out Webmaster Central for a full list of file types we support.

from web contents: Introducing the Structured Data Dashboard 2013
salam every one, this is a topic from google web master centrale blog: Webmaster level: All
Structured data is becoming an increasingly important part of the web ecosystem. Google makes use of structured data in a number of ways including rich snippets which allow websites to highlight specific types of content in search results. Websites participate by marking up their content using industry-standard formats and schemas.
To provide webmasters with greater visibility into the structured data that Google knows about for their website, we’re introducing today a new feature in Webmaster Tools - the Structured Data Dashboard. The Structured Data Dashboard has three views: site, item type and page-level.
Site-level view
At the top level, the Structured Data Dashboard, which is under Optimization, aggregates this data (by root item type and vocabulary schema). Root item type means an item that is not an attribute of another on the same page. For example, the site below has about 2 million Schema.Org annotations for Books (“http://schema.org/Book”)
Itemtype-level view
It also provides per-page details for each item type, as seen below:
Google parses and stores a fixed number of pages for each site and item type. They are stored in decreasing order by the time in which they were crawled. We also keep all their structured data markup. For certain item types we also provide specialized preview columns as seen in this example below (e.g. “Name” is specific to schema.org Product).
The default sort order is such that it would facilitate inspection of the most recently added Structured Data.
Page-level view
Last but not least, we have a details page showing all attributes of every item type on the given page (as well as a link to the Rich Snippet testing tool for the page in question).
Webmasters can use the Structured Data Dashboard to verify that Google is picking up new markup, as well as to detect problems with existing markup, for example monitor potential changes in instance counts during site redesigns.

from web contents: Reorganizing internal vs. external backlinks 2013
salam every one, this is a topic from google web master centrale blog: Webmaster level: All
Today we’re making a change to the way we categorize link data in Webmaster Tools. As you know, Webmaster Tools lists links pointing to your site in two separate categories: links coming from other sites, and links from within your site. Today’s update won’t change your total number of links, but will hopefully present your backlinks in a way that more closely aligns with your idea of which links are actually from your site vs. from other sites.
You can manage many different types of sites in Webmaster Tools: a plain domain name (example.com), a subdomain (www.example.com or cats.example.com), or a domain with a subfolder path (www.example.com/cats/ or www.example.com/users/catlover/). Previously, only links that started with your site’s exact URL would be categorized as internal links: so if you entered www.example.com/users/catlover/ as your site, links from www.example.com/users/catlover/profile.html would be categorized as internal, but links from www.example.com/users/ or www.example.com would be categorized as external links. This also meant that if you entered www.example.com as your site, links from example.com would be considered external because they don’t start with the same URL as your site (they don’t contain www).
Most people think of example.com and www.example.com as the same site these days, so we’re changing it such that now, if you add either example.com or www.example.com as a site, links from both the www and non-www versions of the domain will be categorized as internal links. We’ve also extended this idea to include other subdomains, since many people who own a domain also own its subdomains—so links from cats.example.com or pets.example.com will also be categorized as internal links for www.example.com.
If you own a site that’s on a subdomain (such as www..matrixar.com) or in a subfolder (www.google.com/support/webmasters/) and don’t own the root domain, you’ll still only see links from URLs starting with that subdomain or subfolder in your internal links, and all others will be categorized as external links. We’ve made a few backend changes so that these numbers should be even more accurate for you.
Note that, if you own a root domain like example.com or www.example.com, your number of external links may appear to go down with this change; this is because, as described above, some of the URLs we were previously classifying as external links will have moved into the internal links report. Your total number of links (internal + external) should not be affected by this change.

from web contents: Beyond PageRank: Graduating to actionable metrics 2013
salam every one, this is a topic from google web master centrale blog: Webmaster level: Beginner
Like any curious netizen, I have a Google Alert set up to email me whenever my name is mentioned online. Usually I get a slow trickle of my forum posts, blog posts, and tweets. But by far the most popular topic of these alerts over the past couple years has been my off-handed mention that we removed PageRank distribution data from Webmaster Tools in one of our 2009 releases.
The fact that people are still writing about this almost two years later—usually in the context of “Startling news from Susan Moskwa: ...”—really drives home how much PageRank has become a go-to statistic for some webmasters. Even the most inexperienced site owners I talk with have often heard about, and want to know more about, PageRank (“PR”) and what it means for their site. However, as I said in my fateful forum post, the Webmaster Central team has been telling webmasters for years that they shouldn't focus so much on PageRank as a metric for representing the success of one’s website. Today I’d like to explain this position in more detail and give you some relevant, actionable options to fill your time once you stop tracking your PR!
Why PageRank?
In 2008 Udi Manber, VP of engineering at Google, wrote on the Official Google Blog:
If you look at Google’s Technology Overview, you’ll notice that it calls out relevance as one of the top ingredients in our search results. So why hasn’t as much ink been spilled over relevance as has been over PageRank? I believe it’s because PageRank comes in a number, and relevance doesn’t. Both relevance and PageRank include a lot of complex factors—context, searcher intent, popularity, reliability—but it’s easy to graph your PageRank over time and present it to your CEO in five minutes; not so with relevance. I believe the succinctness of PageRank is why it’s become such a go-to metric for webmasters over the years; but just because something is easy to track doesn’t mean it accurately represents what’s going on on your website.
What do we really want?
I posit that none of us truly care about PageRank as an end goal. PageRank is just a stand-in for what we really want: for our websites to make more money, attract more readers, generate more leads, more newsletter sign-ups, etc. The focus on PageRank as a success metric only works if you assume that a higher PageRank results in better ranking, then assume that that will drive more traffic to your site, then assume that that will lead to more people doing-whatever-you-want-them-to-do on your site. On top of these assumptions, remember that we only update the PageRank displayed on the Google Toolbar a few times a year, and we may lower the PageRank displayed for some sites if we believe they’re engaging in spammy practices. So the PR you see publicly is different from the number our algorithm actually uses for ranking. Why bother with a number that’s at best three steps removed from your actual goal, when you could instead directly measure what you want to achieve? Finding metrics that are directly related to your business goals allows you to spend your time furthering those goals.
If I don’t track my PageRank, what should I be tracking?
Take a look at metrics that correspond directly to meaningful gains for your website or business, rather than just focusing on ranking signals. Also consider metrics that are updated daily or weekly, rather than numbers (like PageRank) that only change a few times a year; the latter is far too slow for you to reliably understand which of your changes resulted in the number going up or down (assuming you update your site more than a few times a year). Here are three suggestions to get you started, all of which you can track using services like Google Analytics or Webmaster Tools:
A “conversion” is when a visitor does what you want them to do on your website. A conversion might be completing a purchase, signing up for a mailing list, or downloading a white paper. Your conversion rate is the percentage of visitors to your site who convert (perform a conversion). This is a perfect example of a metric that, unlike PageRank, is directly tied to your business goals. When users convert they’re doing something that directly benefits your organization in a measurable way! Whereas your PageRank is both difficult to measure accurately (see above), and can go up or down without having any direct effect on your business.
Bounce rate
A “bounce” is when someone comes to your website and then leaves without visiting any other pages on your site. Your bounce rate is the percentage of visits to your site where the visitor bounces. A high bounce rate may indicate that users don’t find your site compelling, because they come, take a look, and leave directly. Looking at the bounce rates of different pages across your site can help you identify content that’s underperforming and point you to areas of your site that may need work. After all, it doesn’t matter how well your site ranks if most searchers are bouncing off of it as soon as they visit.
Clickthrough rate (CTR)
In the context of organic search results, your clickthrough rate is how often people click on your site out of all the times your site gets shown in search results. A low CTR means that, no matter how well your site is ranking, users aren’t clicking through to it. This may indicate that they don’t think your site will meet their needs, or that some other site looks better. One way to improve your CTR is to look at your site’s titles and snippets in our search results: are they compelling? Do they accurately represent the content of each URL? Do they give searchers a reason to click on them? Here’s some advice for improving your snippets; the HTML suggestions section of Webmaster Tools can also point you to pages that may need help. Again, remember that it doesn’t matter how well your site ranks if searchers don’t want to click on it.
Entire blogs and books have been dedicated to explaining and exploring web metrics, so you’ll excuse me if my explanations just scrape the surface; analytics evangelist Avinash Kaushik’s site is a great place to start if you want to dig deeper into these topics. But hopefully I’ve at least convinced you that there are more direct, effective and controllable ways to measure your site’s success than PageRank.
One final note: Some site owners are interested in their site’s PR because people won’t buy links from their site unless they have a high PageRank. Buying or selling links for the purpose of passing PageRank violates our Webmaster Guidelines and is very likely to have negative consequences for your website, so a) I strongly recommend against it, and b) don’t be surprised if we aren’t interested in helping you raise your PageRank or improve your website when this is your stated goal.
We’d love to hear what metrics you’ve found useful and actionable for your website! Feel free to share your success stories with us in the comments here or in our Webmaster Help Forum.

In 2008 Udi Manber, VP of engineering at Google, wrote on the Official Google Blog:
“The most famous part of our ranking algorithm is PageRank, an algorithm developed by Larry Page and Sergey Brin, who founded Google. PageRank is still in use today, but it is now a part of a much larger system.”PageRank may have distinguished Google as a search engine when it was founded in 1998; but given the rate of change Manber describes—launching “about 9 [improvements] per week on the average”—we’ve had a lot of opportunity to augment and refine our ranking systems over the last decade. PageRank is no longer—if it ever was—the be-all and end-all of ranking.
