The Sitemap directive

If you use a Sitemap file to describe your site's structure, indicate the path to the file as a parameter of the Sitemap directive (if you have multiple files, indicate all paths). Example:

User-agent: Yandex
Allow: /

The directive is intersectional, meaning it is used by the robot regardless of its location in robots.txt.

The robot remembers the path to your file, processes your data and uses the results during the next visit to your site.
