Generate a machine-readable guide for AI crawlers in one click. An llms.txt file helps engines like ChatGPT and Perplexity find your most important content and describe you correctly.
Paste your site URL
Your llms.txt
How to use it: save this as a file named llms.txt and upload it to the root of your domain, so it is reachable at yourdomain.com/llms.txt.
Running this check for a client?
A check shows a gap. Closing it is the off-page work we do for SEO agencies, under the agency's name. Send us one client domain: we run the citation test and email you what came back. No charge, and your client is never contacted.
llms.txt is a simple text file you place at the root of your domain. It gives AI crawlers a clean, structured map of your most important pages and a short description of who you are, so they index and quote you more accurately.
Why it matters
AI answer engines move fast and skim. A clear llms.txt reduces the chance they misdescribe your brand or miss your key pages, which protects your reputation and improves your odds of being cited.
Does it replace a sitemap or robots.txt?
No. It complements them. robots.txt controls crawling, your sitemap lists every URL, and llms.txt highlights what matters most for language models in a human-readable form.
Does Google use llms.txt?
Not today. Google has publicly said it doesn't use llms.txt. It's a signal for answer engines like ChatGPT, Perplexity and Claude, not for Google ranking or AI Overviews. To improve how Google's AI Overviews read you, the levers are structured data (schema) and crawlable, answerable content, which CrawlBit also audits and generates.
