The site crawl rate
Yandex robots constantly index sites: crawl them and download pages to their database.
The site crawl rate is the number of requests per second that the robot sends to your site. The crawl speed rate replaces the Crawl-delay directive used in the robots.txt file.
The optimal site crawl speed is calculated using algorithms so that the robot can load the maximum number of pages without overloading the server. Therefore, the Trust Yandex option in the section in Yandex.Webmaster is turned on by default.
Changing the crawl rate
You may need to reduce the crawl speed if you notice a large number of robot requests to the server where your site is located. This can increase the server response time and, as a result, reduce the loading speed of site pages. You can check these indicators in the Yandex.Metrica report.

- View the list of URLs on the All pages).page in Yandex.Webmaster (set the option to
If you find that the robot accesses service pages, prohibit their indexing in the robots.txt file using the Disallow directive. This will help reduce the number of unnecessary robot requests.

- Turn on the Set manually option.
- Move the slider to the desired position. By default, it is set to the optimal crawl rate calculated for your site.
