How to verify Googlebot

Matching the user agent isn't enough, because any client can send it. A real Googlebot request comes from an IP address inside Google's published list:

Block or allow Googlebot in robots.txt

User-agent: Googlebot
Disallow: /

Use Allow: / instead to explicitly permit it, or build a full file with the AI robots.txt generator. robots.txt is a request, not a lock: it only works for bots that honor it, and only real Googlebot traffic would.
