GoogleOther

Google's generic research-and-development crawler - used for internal crawls, including ones that feed AI work, without tying up Googlebot.

GoogleOther is the user-agent Google teams use for one-off and R&D crawls that aren't part of Search indexing - a bucket that includes crawls supporting AI product development. It exists so these fetches don't masquerade as Googlebot.

GoogleOther respects robots.txt rules for its own token, and blocking it does not affect Googlebot, Google Search rankings, or AI Overviews eligibility.
