Frequently asked questions
What is an llms.txt file?
llms.txt is a plain-text file placed at your domain root (yourdomain.com/llms.txt) that tells AI crawlers what your site is about and which pages matter most. It works like robots.txt, but for large language models such as ChatGPT, Claude, Gemini and Perplexity. Sites that publish one tend to be surfaced more consistently in AI answers.
Where do I put the llms.txt file?
Upload it to the root of your website so it is reachable at https://yourdomain.com/llms.txt. On most platforms you add it as a static file; on Shopify or Wix you may need an app or a redirect. Once live, AI crawlers will read it on their next visit — usually within a couple of weeks.
Is llms.txt required for AI search?
It is not strictly required, but it is one of the cheapest wins available for AI visibility. It costs nothing, carries no downside, and gives the engines a clear, machine-readable summary of your business and your most important pages, which improves how accurately and consistently they cite you.
Does an llms.txt guarantee I get cited by ChatGPT?
No single file guarantees citations. llms.txt helps the engines understand and prioritize your site, but citations also depend on FAQ and Article schema, clean crawlable HTML, and self-contained factual passages the model can quote. Run a free AI Visibility audit to see which of those signals you are missing.
How is this different from a sitemap?
A sitemap lists every URL for search-engine crawlers to index. An llms.txt is a short, human-readable summary aimed at AI models: who you are, what you do, and the handful of pages you most want cited. They complement each other — keep both.
