The new standard for helping AI bots understand your site
"What is the llms.txt file, how to create it, and why it became critical in 2026. Step-by-step creation guide and best practices."
What Is llms.txt?
llms.txt is a text file you prepare for AI language models (LLMs) visiting your website. While robots.txt directs search engine bots, llms.txt explains to AI models what your site does, what services you offer, and how you should be cited. It is hosted at the root of your site (/llms.txt).
Why Is llms.txt Critical?
When AI models visit your site, they get lost among hundreds of pages. llms.txt gives them a direct, structured summary. Without this file, AI models may produce incomplete or incorrect information about your brand (hallucinations). llms.txt is the first step in ensuring AI understands you correctly.
llms.txt Structure
A standard llms.txt file consists of these sections:
- Title: Company/product name and brief description
- Services: List of main services you offer
- Differentiators: What sets you apart from competitors
- Target audience: Who you serve
- Contact: Official channels and URLs
- Citation info: How AI models should reference you
Step-by-Step llms.txt Creation
Follow these steps to create llms.txt for your site:
- 1. Write your company info clearly and concisely
- 2. List your main services as bullet points
- 3. State your differentiators from competitors
- 4. Express how you want AI to describe you
- 5. Place the file at your site root (/llms.txt)
- 6. Ensure your robots.txt allows AI bots to crawl
