What is Google-Extended?
Google · AI training · class ai
A robots.txt token, not a separate crawler: it controls whether Google may use your content for Gemini and AI model training. Search is unaffected.
Verdict: Charge it or block it. It does not pay yet.

| Operator | Google · developers.google.com |
|---|---|
| Purpose | AI training crawlers. Collect pages to train models. Bulk, periodic, and the ones most owners want to charge or block. |
| User-agent contains | google-extended |
| robots.txt | User-agent: Google-ExtendedDisallow: / |
| How to verify | No published verification method. Treat the name as a claim, not proof. |
| Should you block it? | Charge it or block it. It does not pay yet. |
| Does it pay? | No. It does not carry a wallet and cannot answer a 402. A site that charges simply serves it nothing. |
