What is llms.txt?
An llms.txt is a structured text file that you place at the root of your website. It functions as a compact summary of your organization and your most important content. The file makes your content accessible to AI in a structured way, without HTML and unnecessary elements.
Llms.txt, what is it for?
AI bots don’t comb through your website completely like traditional search engines like Google and Bing do. They provide direct core information and need a clear overview of your site to do so. By giving AI the right context, content, business details, and reliable URLs, they are less likely to make mistakes or ‘hallucinate’.
An llms.txt file works closely with a robots.txt. Even though they have completely different goals, they complement each other well. Think of llms.txt as a red carpet to guide AI models like ChatGPT, Gemini, or Claude directly to your important pages. You can compare robots.txt to a gatekeeper. The file monitors access control to your website and determines which pages or folders AI crawlers are allowed to see.
What’s in an llms.txt file?
Your llms.txt file is built in a Markdown format, a simple markup language. The file consists of several parts:
- A brief description of your website, mission, and company.
- An overview of your most important products, services, and blogs.
- Structured links with short descriptions to your most valuable content, such as landing pages and articles.
- Additions with instructions on how AI models should cite your content.
Does everyone use an llms.txt file?
The purpose of llms.txt is clear. However, companies rarely use it. The file is currently not an officially accepted internet standard. Major language models like Google, OpenAI, and Perplexity also ignore it for now. Big players mainly use their own crawlers, robots.txt, and structured data.
Ahrefs analyzed the server logs of 137,000 domains in June 2026. This shows that 97% of llms.txt files were never retrieved. So, llms.txt isn’t for ‘search’. At most, the file is a temporary crutch for AI coding tools. Our conclusion remains: llms.txt is not a GEO lever. No major LLM uses it at scale. Focus on your fundamentals.
