Webmaster Tools Show Confusing Webcrawl Errors

Many people submit generated XML sitemaps directly to Google Webmaster Tools. However, when viewing Webcrawl Diagnostics, they see Google report mysterious website crawling problems.

Warnings and Errors in XML Sitemaps

When viewing the list of submitted sitemaps, the webmaster tools shows if any of them have warnings and/or errors. Unfortunately, the red flag graphic is used for both critical errors and warnings. The latter does not prevent Google from indexing an XML sitemap file. You can see the exact error message that causes the sitemap error/warning by clicking the sitemap file in the list.

404 Not Found Errors for URLs

An error often reported for URLs is 404 : Not Found. You may get such errors even if your website has no internal linking errors, and your XML sitemap is 100% correct.

Google follows links from websites all over the internet. Google remembers these links for quite a long time. In our experience, this means that if some website at some point in time has linked to a non-existing page at your website, Google will keep reporting this as an error for a long time.

Examples of how incorrect links to your website can occur on external websites:
  • Someone posted and mistyped a link to your website on a forum.
  • You posted a link on a website which incorrectly shortened it.
