How do I block or allow YaDirectFetcher?
YaDirectFetcher has no robots.txt token of its own. Yandex says it does not follow robots.txt. Controlling its access means recognising its verified identity at the edge (CDN or server).
How do I see whether YaDirectFetcher visits my site?
In your server or CDN access logs, look for YaDirectFetcher in the user agent. Google Analytics does not show these visits: agents do not run its JavaScript.
Anyone can copy the name in a user agent, so counting log lines is not enough. Knocklog reads your site's traffic on any host, confirms who is who, and shows how often YaDirectFetcher came, which pages it read and what that brought you.
How do I know it is really YaDirectFetcher?
The IP's reverse DNS, confirmed forward and back, must end in .yandex.ru or .yandex.net or .yandex.com.
Knocklog runs this check on every visit and separates the genuine agent from impostors.
