Ever since we released the
crawl errors feature in
Webmaster Tools, webmasters have asked for the sources of the URLs causing the errors. Well, we're listening! We know it was difficult for those of you who wanted to identify the cause of a particular "Not found" error, in order to prevent it in the future or even to request a correction, without knowing the source URL. Now, Crawl error sources makes the process of tracking down the causes of "Not found" errors a piece of cake. This helps you improve the user experience on your site and gives you a jump start for
links week (check out our updated post on "
Good times with inbound links" to get the scoop).
In our "Not Found" and "Errors for URLs in Sitemaps" reports, we've added the "Linked From" column. For every error in these reports, the "Linked From" column now lists the number of pages that link to a specific "Not found" URL.
Clicking on an item in the "Linked From" column opens a separate dialog box which lists each page that linked to this URL along with the date it was discovered. The source URL for the 404 can be within or external to your site.
For those of you who just want the data, we've also added the ability to download all your crawl error sources at once. Just click the "Download all sources of errors on this site" link to download all your site's crawl error sources.
Again, if we report crawl errors for your website, you can use crawl error sources to quickly determine if the cause is from your site or someone else's. You'll have the information you need to contact them to get it fixed, and if needed, you can still put in place
redirects on your own site to the appropriate URL. Just sign in to
Webmaster Tools and check it out for your verified site. You can help people visiting your site—from anywhere on the web—find what they're looking for.
