llms.txt for SEO: Make Your Site AI-Readable
Technical signals for AI and LLMs. Learn what llms.txt is and how to add it so ChatGPT and other models can read and cite your brand correctly.
What Is llms.txt and Why Do You Need It?
llms.txt is a standard file you host on your site (like robots.txt) that tells AI models and LLMs who you are, what you do, and how to cite you. It makes your website AI-readable so ChatGPT, Claude, Gemini, and Perplexity can describe your brand accurately. For the full picture of how AI learns your brand (RAG, training data, and technical signals), see How AI Learns Your Brand.
AI-Readable Site Signals
Signal to AI what your company does and how to represent you.
Unlike robots.txt (which tells crawlers what to skip), llms.txt tells AI what to read and how to describe you. It supports better AI brand clarity and helps reduce AI brand confusion. For more on consistency across models, see AI brand clarity.
llms.txt for SEO and AI
Improve how AI recommends and cites your content.
When your site has clear, structured signals, AI is more likely to recommend you when users ask for your category and to cite your content in answers. Combine llms.txt with an AI brand awareness audit to see how models currently describe you.
Why llms.txt Matters for Your Brand
AI models learn from many sources. Giving them a single, authoritative file (llms.txt) with your positioning, glossary, and preferred phrasing helps them describe you consistently and cite you when users ask. That supports both AI brand clarity and getting AI to cite you in answers.
