Search intent
Users confuse Google-Extended with Googlebot and need a safe copy-paste pattern.
Practical checklist
- Google-Extended is a robots.txt control token.
- It does not show as a separate HTTP user-agent string in logs.
- Blocking Googlebot is a different decision and can affect normal search traffic.
