GoogleOther:
what it is and how to verify it.

GoogleOther is Google’s generic crawler, used by various product teams to fetch publicly accessible content — including one-off crawls for internal research and development. Google introduced it to take non-Search workloads off Googlebot, so that a Googlebot hit means Search indexing and nothing else.

For site owners the practical meaning is ambiguity: a GoogleOther hit tells you a Google team wanted your content, but not which team or why. AI-related R&D crawling is widely assumed to be part of its workload, which is why GoogleOther shows up in AI-crawler audits despite its generic charter.

It shares infrastructure with Googlebot — same published IP ranges, same crawl-*.googlebot.com reverse DNS — and it respects robots.txt, so you can rate-limit or block it without touching Googlebot’s Search crawling.
