1% of 30,177 measured domains disallow googleother in robots.txt at the site root. Separately, and independently of robots.txt, 17.4% of 30,185 reachable domains refuse an AI crawler user agent at the network edge on two consecutive probes from different locations - a refusal the site's own robots.txt does not declare and its owner often has not chosen.

What it is definition
Generic Google crawler used by product teams for one-off fetches such as internal research and development.
GoogleOther is operated by Google and classified here as model training. These agents collect text and images that may end up in a training corpus. Disallowing one withholds new content from the next model. It does not withdraw anything collected before the disallow, and it does not remove the site from any answer engine.
Disallowing googleother withholds content crawled from that point on from Google's training data. It does not withdraw pages collected in earlier crawls, it does not reach copies already sitting in third-party datasets, and it does not remove the site from any answer surface.

How to allow it, how to block it robots.txt
User-agent: googleother
Allow: /Absent any rule, the agent is already allowed, so this group only matters when your * group disallows something. Naming the agent replaces the * group for it entirely, so repeat here every disallow you still want to apply to it.
User-agent: googleother
Disallow: /Disallowing googleother withholds content crawled from that point on from Google's training data. It does not withdraw pages collected in earlier crawls, it does not reach copies already sitting in third-party datasets, and it does not remove the site from any answer surface.

This list is served from a cache rebuilt just now. It is discarded the moment a rescan records a policy change for this agent, so a site that has just changed its robots.txt will drop off it within one scan rather than waiting for the cache to expire.

Google runs 5 agents in this registry, and they do different jobs. Blocking one says nothing about the others.
Common questions answered
Does blocking GoogleOther remove me from Google's AI products?
No, not by itself. GoogleOther collects content for training, not for the index that answers questions. Google's answer surfaces are governed separately by googlebot, googlebot-news and google-cloudvertexbot, which stay allowed unless you disallow them too. Content collected before the disallow is not withdrawn.
How do I verify GoogleOther requests are genuine?
Run a reverse DNS lookup on the source address. It must resolve to a host under googlebot.com or google.com, and a forward lookup of that host must return the same address. Google also publishes its crawler ranges as JSON, so an address match works when reverse DNS is unavailable.
