# Gemini ( Google )

**Google Gemini**: Google doesn’t publish CIDRs for crawlers. The official method is **reverse-DNS verification** (IP ⇄ `googlebot.com`/`google.com`/`googleusercontent.com`). Do that at your edge and pass a boolean into PostHog (e.g., `google_verified_crawler=true`). IP-only in PostHog isn’t feasible.
