The technical details

How to identify it

Look for the YandexBot identifier in a request’s User-Agent. This is a name match, not identity verification. Version strings may change.

How to check identity

Confirm reverse DNS under yandex.ru, yandex.net or yandex.com, then resolve that hostname back to the original request IP.

Access and robots.txt

The operator documents robots.txt rules for this identifier.

Optional full-site opt-out. Merge with existing rules only if intended. robots.txt does not secure private content.

User-agent: YandexBot
Disallow: /
Seeing 403 or 404 responses?

403 means access was denied; 404 means the resource was not found. Compare the public path, request time, edge security event and origin response to find the cause.

Separate intended restrictions and secret-file probes from pages that should work. A User-Agent name alone does not justify allowing a request.
