The site crawl rate
Yandex robots constantly index sites by crawling them and downloading pages to the search database.
The site crawl rate is the number of requests per second that the robot sends to your site.
The optimal crawl rate is calculated using algorithms so that the robot can load the maximum number of pages without overloading the server. This is why the Trust Yandex option is turned on by default on the page in Yandex.Webmaster.
