What is llms.txt?
llms.txt is a simple markdown file you place at the root of your website (yoursite.com/llms.txt). It gives large language models a concise, curated overview of your site — your name, a one-line summary, and a list of your most important pages with short descriptions. Think of it as a friendly briefing for AI: instead of scraping and guessing, the model gets a clean map of what you do and what to cite.
llms.txt and Generative Engine Optimization (GEO)
As people ask AI assistants questions instead of typing into Google, being represented accurately inside AI answers is the new frontier — Generative Engine Optimization. A clear llms.txt is one of the easiest first steps: it helps AI tools understand, summarize and cite your brand correctly. It won't guarantee a citation, but it removes the most common reason AI gets your site wrong: bad or missing context.
SeenByAI is a free utility. llms.txt is an emerging, voluntary standard; adoption by individual AI providers varies and continues to evolve.
