Webmaster Level: All

A little over six months ago we released a new malware diagnostic tool in Webmaster Tools with the help of Lucas Ballard from the anti-malware team. This feature has been a great success; many of you were interested to know if Google had detected malicious software in your site, and you used the tool's information to find and remove that malware and to fix the vulnerabilities in your servers.

Well, a few days ago we promoted the malware diagnostics tool from Labs to a full Webmaster Tools feature. You can now find it under the Diagnostics menu. Not only that, we also added support for malware notifications. As you may already know, if your site has malware we may show a warning message in our search results indicating that the site is potentially harmful. If this is the case, you should remove any dangerous content as soon as possible and patch the vulnerabilities in your server. After you've done that, you can request a malware review in order to have the warning for your site removed. What's new in our latest release is that the form to request a review is now right there with the rest of the malware data:

Update: Code Search Sitemaps are no longer supported. More information.

The Sitemaps team is continuing its trend of extending the Sitemap Protocol for specific products and content types. Our latest work with the Google Code Search team now enables you to create Sitemaps that contain information about public source code you host and would like to include in Code Search. There's more information about this new functionality on the Google Code blog. If you're eager to get going, take a look at our Help Center documentation, create a Code Search Sitemap, sign into Google Webmaster Tools, and submit a Sitemap for Code Search!

Sitelinks are extra links that appear below some search results in Google. They serve as shortcuts to help users quickly navigate to the important pages on your site.

Selecting pages to appear as sitelinks is a completely automated process. Our algorithms parse the structure and content of websites and identify pages that provide fast navigation and relevant information for the user's query. Since our algorithms consider several factors to generate sitelinks, not all websites have them.

Now, Webmaster Tools lets you view potential sitelinks for your site and block the ones you don't want to appear in Google search results. Because sitelinks are extremely useful in helping users navigate your site, we don't typically recommend blocking them. However, occasionally you might want to exclude a page from your sitelinks, for example: a page that has become outdated or unavailable, or a page that contains information you don't want emphasized to users. Once you block a page, it won't appear as a sitelink for 90 days unless you choose to unblock it sooner. It may take a week or so to remove a page from your sitelinks, but we are working on making this process faster.

To view and manage your sitelinks, go to the Webmaster Tools Dashboard and click the site you want. In the left menu click Links, then click Sitelinks.
Thanks for your feedback and stay tuned for more updates!


Update: the user-interface for this feature has changed. For more information, please see the Sitelinks Help Center article.

All sites can benefit from submitting a Sitemap to Google Webmaster Tools. You may help us to do a better job of crawling and understanding your site, especially if it has dynamic content or a complicated architecture.

Besides, you will have access to more information about your site, for example the number of pages from your Sitemaps that are indexed by Google, any errors Google found with your Sitemap, as well as warnings about potential problems. Also, you can submit specialized Sitemaps for certain types of content including Video, Mobile, News and Code.
More information about the benefits of submitting a Sitemap to Google Webmaster Tools can be found here.

The instructions in our Help Center explain that you can associate a country or region to an entire domain, individual subdomains or subdirectories. A quick tip: if, for instance, you are targeting the UK market, better ways of structuring your site would be example.co.uk, uk.example.com, or example.com/uk/. Google can geolocate all of those patterns.

If your domain name has no regional significance, such as www.example.com, you can still associate your website with a country or region. To do that you will need to verify the domain, or the subdomains and/or subdirectories one by one in your Webmaster Tools account and then associate each of them with a country/region. However, for the moment we don't support setting a geographical target for patterns that can't be verified such as, for example, www.example.com/?region=countrycode.

I have a news site and it is not entirely crawled. Why? Other crawlers had no problem crawling us...

First off, make sure that nothing prevents us from crawling your news site - the architecture of your site or the robots.txt file. Also, we suggest you sign up for Webmaster Tools and submit your content. We specifically have the News Sitemap protocol for sites offering this type of content. If you take advantage of this feature, we can give you more information on which URLs we had trouble with and why. It really rocks!

As a site owner, you control what content of your site is indexed in search engines. The easiest way to let search engines know what content you don't want indexed is to use a robots.txt file or robots meta tag. But sometimes, you want to remove content that's already been indexed. What's the best way to do that?

As always, the answer begins: it depends on the type of content that you want to remove. Our webmaster help center provides detailed information about each situation. Once we recrawl that page, we'll remove the content from our index automatically. But if you'd like to expedite the removal rather than wait for the next crawl, the way to do that has just gotten easier.

For sites that you've verified ownership for in your webmaster tools account, you'll now see a new option under the Diagnostic tab called URL Removals. To get started, simply click the URL Removals link, then New Removal Request. Choose the option that matches the type of removal you'd like.



Individual URLs
Choose this option if you'd like to remove a URL or image. In order for the URL to be eligible for removal, one of the following must be true:

• The URL must return a status code of either 404 or 410.
• The URL must be blocked by the site's robots.txt file.
• The URL must be blocked by a robots meta tag.

Once the URL is ready for removal, enter the URL and indicate whether it appears in our web search results or image search results. Then click Add. You can add up to 100 URLs in a single request. Once you've added all the URLs you would like removed, click Submit Removal Request.

A directory
Choose this option if you'd like to remove all files and folders within a directory on your site. For instance, if you request removal of the following:

http://www.example.com/myfolder

this will remove all URLs that begin with that path, such as:

http://www.example.com/myfolder
http://www.example.com/myfolder/page1.html
http://www.example.com/myfolder/images/image.jpg

In order for a directory to be eligible for removal, you must block it using a robots.txt file. For instance, for the example above, http://www.example.com/robots.txt could include the following:

User-agent: Googlebot
Disallow: /myfolder

Your entire site
Choose this option only if you want to remove your entire site from the Google index. This option will remove all subdirectories and files. Do not use this option to remove the non-preferred version of your site's URLs from being indexed. For instance, if you want all of your URLs indexed using the www version, don't use this tool to request removal of the non-www version. Instead, specify the version you want indexed using the Preferred domain tool (and do a 301 redirect to the preferred version, if possible). To use this option, you must block the site using a robots.txt file.

Cached copies

Choose this option to remove cached copies of pages in our index. You have two options for making pages eligible for cache removal.

Using a meta noarchive tag and requesting expedited removal
If you don't want the page cached at all, you can add a meta noarchive tag to the page and then request expedited cache removal using this tool. By requesting removal using this tool, we'll remove the cached copy right away, and by adding the meta noarchive tag, we will never include the cached version. (If you change your mind later, you can remove the meta noarchive tag.)

Changing the page content
If you want to remove the cached version of a page because it contained content that you've removed and don't want indexed, you can request the cache removal here. We'll check to see that the content on the live page is different from the cached version and if so, we'll remove the cached version. We'll automatically make the latest cached version of the page available again after six months (and at that point, we likely will have recrawled the page and the cached version will reflect the latest content) or, if you see that we've recrawled the page sooner than that, you can request that we reinclude the cached version sooner using this tool.

Checking the status of removal requests
Removal requests show as pending until they have been processed, at which point, the status changes to either Denied or Removed. Generally, a request is denied if it doesn't meet the eligibility criteria for removal.


To reinclude content
If a request is successful, it appears in the Removed Content tab and you can reinclude it any time simply by removing the robots.txt or robots meta tag block and clicking Reinclude. Otherwise, we'll exclude the content for six months. After that six month period, if the content is still blocked or returns a 404 or 410 status message and we've recrawled the page, it won't be reincluded in our index. However, if the page is available to our crawlers after this six month period, we'll once again include it in our index.

Requesting removal of content you don't own
But what if you want to request removal of content that's located on a site that you don't own? It's just gotten easier to do that as well. Our new Webpage removal request tool steps through the process for each type of removal request.

Since Google indexes the web and doesn't control the content on web pages, we generally can't remove results from our index unless the webmaster has blocked or modified the content or removed the page. If you would like content removed, you can work with the site owner to do so, and then use this tool to expedite the removal from our search results.

If you have found search results that contain specific types of personal information, you can request removal even if you've been unable to work with the site owner. For this type of removal, provide your email address so we can work with you directly.



If you have found search results that shouldn't be returned with SafeSearch enabled, you can let us know using this tool as well.

You can check on the status of pending requests, and as with the version available in webmaster tools, the status will change to Removed or Denied once it's been processed. Generally, the request is denied if it doesn't meet the eligibility criteria. For requests that involve personal information, you won't see the status available here, but will instead receive an email with more information about next steps.

What about the existing URL removal tool?
If you've made previous requests with this tool, you can still log in to check on the status of those requests. However, make any new requests with this new and improved version of the tool.

In our recent Webmaster Tools launch, we went live in 14 new languages, bringing our total language support count to 40! With the launch of Bulgarian, Catalan, Croatian, Filipino, Greek, Indonesian, Lithuanian, Latvian, Portuguese (Portugal), Slovak, Slovenian, Serbian, Ukrainian and Vietnamese, Webmaster Tools joins Google products such as Google.com, AdWords, Gmail and Toolbar to reach the 40 Language Initiative (Google's company-wide initiative to make sure Google products are available in the 40 languages read by more than 98% of Internet users).

Our team is very excited to reach so many of you by offering our tools in 40 languages. At the same time, both the Google Localization and Webmaster Tools teams know that there's more room for improvements in the features and quality of our service. We hope to hear your input in the comments below, especially on the linguistic quality of our new languages.
