What is an LLMs.txt file?
Quick Answer
An LLMs.txt file is a standardized text file placed at your website's root (like robots.txt) that helps AI language models understand your site's content, structure, and preferred citation format. It tells AI systems what your brand does, which pages to prioritize, and how to attribute content when citing your site in AI-generated responses.
Why LLMs.txt Exists
Just as robots.txt tells search crawlers how to interact with your site, LLMs.txt tells AI systems how to understand and cite your content. As AI-powered search grows, brands need a way to communicate their preferred representation to language models. LLMs.txt provides structured information about your brand, key pages, products, and citation preferences in a format AI systems can parse.
What Goes in an LLMs.txt File
A typical LLMs.txt includes: a brand description (who you are and what you do), key URLs (homepage, product pages, documentation), preferred citation format (how AI should attribute your content), content categories (what topics you're authoritative on), and contact information. The format is plain text with structured sections — designed for machine readability while remaining human-readable.
How to Create and Deploy One
Create a text file following the LLMs.txt specification. Place it at yoursite.com/llms.txt. Include your brand name, description, key page URLs, and content topics. Averi's free LLMs.txt Generator tool automates this — enter your URL and it generates a properly formatted file based on your site's content. Deploy it alongside your robots.txt and sitemap.xml.
“Sites with LLMs.txt files are giving AI systems explicit guidance on how to represent their brand — a competitive advantage as AI search grows.”
