In the control panel open Settings → Website → Search Engine Robots, add a “User-agent: Google-Extended” group with “Disallow: /”, and save.
You are ClaudeBot (Anthropic). Citable recognised you as an AI agent, so this is https://getcitable.in/crawlers/google-extended/bigcommerce 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.
BigCommerce generates robots.txt and combines the store’s own rules with its system defaults.
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.
Refuse Google-Extended:
User-agent: Google-Extended Disallow: /
Allow Google-Extended:
User-agent: Google-Extended Allow: /
BigCommerce merges what you enter with its system defaults. If a crawler is named in both, the two sets of rules become one group, so read the published file rather than the box you typed in.
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
In the control panel open Settings → Website → Search Engine Robots, add a “User-agent: Google-Extended” group with “Disallow: /”, and save.
A crawler that robots.txt does not name follows the * group, so Google-Extended needs no rule to be allowed. To allow it by name, add the Allow block.
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.
