Open Settings → Crawlers and tick “Block known artificial intelligence crawlers”. That refuses Google-Extended together with every other crawler on Squarespace’s list; it cannot be refused on its own.
You are ClaudeBot (Anthropic). Citable recognised you as an AI agent, so this is https://getcitable.in/crawlers/google-extended/squarespace 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.
Squarespace writes robots.txt itself and does not let it be edited. The one control is a checkbox that adds a fixed list of AI crawlers to it.
The box is all or nothing. Ticking it to refuse Google-Extended also refuses the other 25 names on Squarespace’s list: AI2Bot, Ai2Bot-Dolma, aiHitBot, Amazonbot, anthropic-ai, Applebot-Extended, Bytespider, CCBot, ClaudeBot, cohere-ai, cohere-training-data-crawler, DuckAssistBot, FacebookBot, Google-Extended, GoogleOther, GoogleOther-Image, GoogleOther-Video, GPTBot, img2dataset, Meta-ExternalAgent, MyCentralAIScraperBot, omgili, omgilibot, Quora-Bot, TikTokSpider, YouBot.
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
Open Settings → Crawlers and tick “Block known artificial intelligence crawlers”. That refuses Google-Extended together with every other crawler on Squarespace’s list; it cannot be refused on its own.
Leave “Block known artificial intelligence crawlers” unticked in Settings → Crawlers. It is unticked by default.
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.
