## ABOUT THIS CRAWLER

Used by agents hosted on Google infrastructure to navigate the web and act on a user’s request.

**Usually means:** An AI agent is browsing your site on someone’s behalf, which may be more than just reading one page.

## USER AGENT

Google-Agent

We match these as user-agent tokens, not full browser strings. Providers may add surrounding version or product text.

## IP VERIFICATION

Verified when user agent and IP range both match

We first match the crawler’s user-agent token, then compare the request IP with the ranges published by the crawler’s operator.
