How to Create llms.txt: The robots.txt for AI
llms.txt gives AI systems a clear, machine-readable summary of what your company is, what it offers, and which pages matter most. This guide explains what to include, what not to include, and how llms.txt fits into a broader answer-engine optimization workflow.

What llms.txt actually does
llms.txt is not a ranking hack. It is a clarity layer. The file gives AI systems a compact statement of what your company is, what it does, and which pages provide the strongest supporting context. That helps reduce ambiguity when your brand name, category, or feature language is easy to misread.
For AEO teams, llms.txt is especially useful when the category is new or poorly standardized. It complements your site, not replaces it. If the rest of the site is unclear or weak, the file alone will not fix discoverability.
What to include
Keep the file factual and concise. Describe the company, define the category, link to the highest-value commercial and educational pages, and include the clearest proof pages you have. Treat it like a guide for machines, not a homepage slogan.
- Company and category definition in one or two plain-language sentences.
- Key pages: homepage, pricing, compare hub, category explainer, important glossary pages.
- Trusted proof pages such as security, methodology, integrations, and product documentation.
Common mistakes
The most common failure is writing llms.txt like ad copy. Models do not need another list of slogans. They need stable facts, entity clarity, and obvious page ownership.
Another mistake is publishing the file while ignoring the supporting pages it references. If the homepage, glossary, and comparison pages do not reinforce the same narrative, llms.txt becomes an isolated statement rather than part of a coherent site structure.
Where llms.txt fits in the workflow
llms.txt belongs in the technical foundation layer. It should sit alongside clean crawler access, structured data, clear category copy, and answer-ready page formatting. Once those basics are in place, the file makes the overall system more consistent.
For most software teams, it is a quick win, not the whole strategy. The bigger gains usually come from publishing the commercial and comparison pages that give models something worth citing.
