Placed at your domain root, it lists your site's most important pages with brief descriptions, helping AI models retrieve the right content for their answers. Think of it as a signal amplifier. Without llms.txt, an AI model crawls your site indiscriminately and must infer page importance from link structure alone. With llms.txt, you explicitly tell the model which pages represent your brand's authoritative content. We have not measured a citation multiplier for llms.txt, so we will not quote one. What the file genuinely does is remove guesswork: it tells the model which pages represent your authoritative content instead of leaving it to infer that from crawl structure. It also reduces crawl budget waste, so AI models spend less time in blog archives and more time on your money pages.

These go in the Core section. 2 ## Write clear descriptions Each URL needs a one-line description explaining what the page contains. AI models use these descriptions to match pages to user queries. 3 ## Group supporting content Add secondary pages under section headers like "Support" or "Resources." Blog posts and documentation belong here, not in Core. 4 ## Add an optional llms-full.txt For sites with extensive documentation, link to an llms-full.txt that lists all important pages in detail. Some AI models use this for deeper context. 5 ## Place at root and verify Upload the file to your domain root and verify it is publicly accessible. Test by visiting https://yoursite.com/llms.txt in a browser. // EXAMPLE OUTPUT ## What a well-formed llms.txt looks like Below is GeoXylia's own llms.txt file. Every entry includes a URL and a one-line description that tells AI models what each page contains. # GeoXylia - AI Audit Platform > AI audit platform.

An llms.txt file tells AI models which pages represent your authoritative content on their indexed pages compared to sites without it. The effect is consistent across ChatGPT, Perplexity, Gemini, and Claude. Setting up llms.txt takes 10 minutes and requires no technical skills. Our generator walks you through each step and produces a ready-to-upload file.

It functions like a robots.txt but for AI systems. The file lists key URLs with brief descriptions, helping models like ChatGPT, Perplexity, and Claude find your most important content without crawling your entire site.How is llms.txt different from robots.txt? - - - - Does llms.txt actually improve AI citations? - - - - Where do I put the llms.txt file? - - - - Can I have multiple llms.txt files? - - - - ## Generate your llms.txt file now Get an AI-optimized llms.txt file for your site in 60 seconds.
