Should you block GoogleOther-Image?

Blocking it can limit image-oriented Google product crawls without targeting regular Googlebot directly.

What blocking each Google bot does
Google bot	Job	If you block it
Google-Extended	Control token	Disallowing it limits future Gemini training and grounding uses covered by the token. Google says it does not affect Search inclusion or ranking.
Googlebot	Search	Blocking Googlebot can remove pages from Google Search and eligibility for Google AI features that depend on Search indexing.
Google-Agent	User fetch	Blocking it can prevent a Google agent from retrieving a page while completing a user-directed task. It is separate from Google Search crawling.
Google-GeminiNotebook	User fetch	A hit usually means a person added your page as a source, not that Google is crawling your site broadly.
Google-CloudVertexBot	Other	A hit usually relates to a configured Vertex AI workflow rather than broad public search crawling.
GoogleOther	Other	Blocking it may affect Google product-specific crawling but is separate from primary Search indexing policy.
GoogleOther-ImageThis page	Other	Blocking it can limit image-oriented Google product crawls without targeting regular Googlebot directly.
GoogleOther-Video	Other	Blocking it can limit video-oriented Google product crawls without targeting regular Googlebot directly.

robots.txt

User-agent: GoogleOther-Image
Disallow: /

Asks GoogleOther-Image not to crawl any page. Other Google bots are unaffected. Add it to the robots.txt file at the root of your site, above any wider rules.

Ignored robots.txt?

GoogleOther-Image access decides whether Google can fetch your pages. Whether those pages get used in generated answers is a separate question, so track your presence in Google's AI results rather than treating crawl volume as visibility.

Also seen under Google’s name, but not in its current documentation: GoogleAgent-Mariner, Gemini-Deep-Research, Google-NotebookLM, Google-Gemini-CLI, Google-Firebase. Rules naming them control no documented Google crawler.

Match the name
Search your server or CDN log for GoogleOther-Image, case-insensitive. A match is a clue, not proof.
2
Check the published IP ranges and reverse DNS
Google also documents reverse DNS: a genuine common crawler’s hostname ends in googlebot.com or google.com and resolves back to the same address. developers.google.com/static/search/apis/ipranges/googlebot.json

Is this really GoogleOther-Image?

What is the difference between GoogleOther-Image, Google-Extended and Googlebot?

GoogleOther-Image is for other uses, separate from training and search. Google-Extended is for training: it collects pages that may be used to build models. Googlebot is for search: it indexes pages so answers can find and cite them. Google-Agent is a user fetch: it reads a page when a person asks about it. Google-GeminiNotebook is a user fetch: it reads a page when a person asks about it. Google-CloudVertexBot is for other uses, separate from training and search. GoogleOther is for other uses, separate from training and search. GoogleOther-Video is for other uses, separate from training and search. Each has its own robots.txt token, so a rule for one does not cover the others.

How do I know a request really came from GoogleOther-Image?
