Does yandex.ru block AI crawlers?
Partly. As of October 19, 2026, yandex.ru's robots.txt blocks none of the 17 AI crawlers we check from the whole site, but keeps all 17 out of parts of it. 1 of them is named in a group of its own; the others follow its rules for every crawler.
It has no llms.txt (HTTP 404). The homepage redirects to a host whose robots.txt we could not read, so we did not fetch it.
Each crawler, by its robots.txt rules
From https://yandex.ru/robots.txt (40,657 bytes, 5 user-agent groups), parsed per RFC 9309. Blocked: no path allowed. Partly blocked: some paths disallowed. The rule counts are those of the groups that apply.
