Robots.txt file not found

The indexing robot requests the robots.txt file several times a day and updates information about it in its database. It the robot cannot load the file, a warning appears in Yandex.Webmaster.

In the service, check the availability of the robots.txt file. If the file is still unavailable, add it. If you can't do this yourself, contact your hosting provider or domain name registrar. After the file is added, the data in Yandex.Webmaster will be updated within a few days.

Errors were detected in the robots.txt file

Check the robots.txt file of your site. To fix errors, see the directive descriptions.

No Sitemap files are currently used by the indexing bot

The Sitemap file it is an auxiliary tool for indexing a site. It allows you to regularly inform the robot about new pages on the site. This warning appears if the robot is not using any Sitemap files for the site.

For the robot to start using the created file, add it to Yandex.Webmaster and wait for the robot to process the file. This can take up to two weeks. After that, the warning will disappear.

Errors found in Sitemap files

Check the Sitemap file of your site. The check may detect the error “Unknown tag”. This means that the file contains elements that are not supported by Yandex. The unsupported elements are ignored by the robot during Sitemap processing, but data from supported elements is still taken into account. You don't have to change the contents of the file. Learn more about supported Sitemap elements.

The title element and the Description metatag are missing

The title element and Description metatag are used for generating a good site description in search results. For more information, see Displaying the site title and description in search results.

If either or both of these elements are missing from your site, add them to the HTML code of the pages and save the changes. If the elements have already been added, wait for the robot to recrawl the pages. The error message will disappear after reindexing.

The favicon file is not accessible to the robot

If this issue is displayed for your site, it means the favicon is not appearing in search results. Go to the Yandex.Webmaster Diagnostics → Site diagnostics page (Possible problems section) and find the reason why the robot couldn't load the file, then follow the instructions:

Error Solution
The file responds with an HTTP code other than 200 OK Check the server response. The response should be 200 OK. For other response statuses, see Server response check.
The file redirects to another URL
Incorrect data type Check the value of the type parameter in the file URL. It should match the file format.
