Google-Extended Robots.txt Rules

Use Google-Extended correctly without blocking normal Google Search crawling.

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.
