Crawl errors

The crawl errors page

The Crawl Errors page provides details about the URLs that Google could not successfully crawl or that returned an HTTP error code. This page has two main sections:

Site errors

This section shows the main issues for the past 90 days that prevented Googlebot from accessing your entire site (click any box to display its chart):

  • DNS errors—the Domain Name System, which translates the name of your site to a numerical address for the server that provides your website files.
  • Server errors—your host provider's server functionality, such as connection reliability and speed.
  • robots.txt failure—the file that Google must first access before it can crawl your site. It tells Google which pages it can and cannot access.

  • Desktop
