Add a “User-agent: Google-Extended” group with “Disallow: /” to the robots.txt the origin serves, or switch on Cloudflare’s managed robots.txt, which already refuses it. No request carries the name Google-Extended, so a rule on the user agent never matches it. robots.txt is the only place this name has any effect.
You are ClaudeBot (Anthropic). Citable recognised you as an AI agent, so this is https://getcitable.in/crawlers/google-extended/cloudflare with the UI removed — the content only. A browser asking for the same address gets the full designed page.
Google-Extended is not a crawler. It sends no requests of its own: Google reads pages with its existing crawlers, and Google-Extended is the name robots.txt uses to say whether those pages may be used to train Gemini models.
Cloudflare does not hold a site’s robots.txt; the origin does. But it can add to that file, and it can refuse a crawler before the origin is ever asked.
A group that names a crawler replaces the * group for that crawler; it does not add to it. Paths the * group closes are open to a crawler with its own group unless they are repeated there.
robots.txt at the origin, refusing Google-Extended:
User-agent: Google-Extended Disallow: /
robots.txt at the origin, allowing Google-Extended:
User-agent: Google-Extended Allow: /
With the managed robots.txt on, Cloudflare’s rules come first in the file a crawler reads. They refuse Google-Extended whatever the origin’s file says below them.
No request carries the name Google-Extended, so a rule on the user agent never matches it. robots.txt is the only place this name has any effect.
Read the file a crawler is given and look for the group that names Google-Extended. There is no request to test: Google-Extended never sends one.
The request:
curl -s https://your-site.example/robots.txt
Add a “User-agent: Google-Extended” group with “Disallow: /” to the robots.txt the origin serves, or switch on Cloudflare’s managed robots.txt, which already refuses it. No request carries the name Google-Extended, so a rule on the user agent never matches it. robots.txt is the only place this name has any effect.
Do not refuse it in the origin’s robots.txt, and keep Cloudflare’s managed robots.txt off: when on, it writes “Disallow: /” for this name.
No request carries the name Google-Extended, so a rule on the user agent never matches it. robots.txt is the only place this name has any effect.
Refusing Google-Extended tells Google not to use your pages to train Gemini models. It does not change whether Googlebot reads them, and Google says it is not used as a ranking signal and does not affect inclusion in Google Search.
Citable strips the UI from a website for AI agents and serves them only the content.
When an AI agent — ChatGPT, Claude, Perplexity or any of the 81 that Citable recognises — opens a page, Citable removes the theme, scripts, navigation and layout and serves only the content: the same facts, at the same URL, on the site's own domain. People and Google still get the full designed page.
