GoogleOther

Google’s generic crawler for research and development crawls by product teams. It is not used for Google Search.

Operator: Google
Purpose: Model training. Crawlers that collect pages to train models. Blocking them does not affect search or AI answers.
robots.txt token: GoogleOther
User agent: GoogleOther
Documentation: developers.google.com/search/docs/crawling-indexing/google-common-crawlers#googleother

Block GoogleOther

Add a group naming it to /robots.txt. Compliant crawlers stop before requesting any page. A firewall rule on the user agent is the only way to enforce it against crawlers that ignore robots.txt.

User-agent: GoogleOther
Disallow: /

Allow GoogleOther when everything else is blocked

A group naming the bot wins over User-agent: *, so an explicit allow lets it in while your catch-all rules stay in place.

User-agent: GoogleOther
Allow: /

User-agent: *
