FAQ

Common questions about AI visibility

It shows how many AI crawlers and search engines can reach your site right now, out of 100 points. The score combines two signals: whether each AI agent is allowed to access your pages, and whether you publish an llms.txt file.

robots.txt is a text file at the root of your domain that tells crawlers, including search engines and AI bots, which parts of your site they can access. It's the same file that already controls how Google indexes your pages.

llms.txt is a newer file, published at yourdomain.com/llms.txt, that gives AI systems a clean, direct summary of your site's content. It isn't required yet, but publishing one is an easy way to tell AI answer engines what your site is about.

13 crawlers across three categories: search engines like Googlebot and Bingbot, AI training crawlers like GPTBot, ClaudeBot and Common Crawl, and AI answer engines like ChatGPT's live browsing, Perplexity and OpenAI's search crawler.

Yes. isvisible.ai has a public API, and the exact request format is published at isvisible.ai/llms.txt specifically so AI assistants can read it. Ask ChatGPT, Claude or any AI assistant with web access to check a domain using the isvisible.ai API, and it can send the request and read the score back to you.

ChatGPT, Claude, Perplexity and Google AI Overviews are becoming a new way people find and evaluate businesses. If your site blocks these crawlers, your content can't be cited or recommended in AI answers, even if it ranks well in traditional search.

Yes. Enter your URL and get a full report in seconds, no account or credit card required.

Agent access is worth 80 points and llms.txt is worth 20. If a site has no robots.txt and the live probe can't run either, access can't be confirmed, so agent points count at half weight until one of those signals is available.
