LLMs.txt
llms.txt is a small text file on your site that shows AI models, in a structured way, which content matters and how to understand it. It makes your foundation machine-readable — so assistants capture and recommend your business without errors.
llms.txt is a simple text file you place in the root directory of your site – similar to the well-known robots.txt, but for AI language models instead of search-engine crawlers. It summarises which content on your site matters, how it connects and where the reliable facts are.
The point behind it: AI assistants don't have to fight their way through layout, menus and scripts, but get a clear, machine-readable map of your content. That lowers the chance of a model spreading outdated or wrong information about you.
llms.txt is no magic bullet, but one building block of a machine-readable foundation. It works best when the linked content is itself cleanly structured and up to date. What comes after the file is covered in llms.txt is only step one.

Frequently asked questions.
Do I absolutely need an llms.txt?
It is not a Google ranking signal (Google says so itself) — but it takes minutes to create and is useful as orientation for AI agents. A cheap addition, not a miracle cure.
What does GEO get me — why should my website be cited by AI?
When more and more people get their answers straight from ChatGPT, Perplexity or Google's AI, whether you get found is no longer decided by your Google ranking alone — but by whether the AI names you as a source. That is exactly what GEO (Generative Engine Optimization) does: it prepares your content so AI systems read it correctly, understand it and cite it in their answers. The benefit is concrete: you get recommended when a potential customer asks the AI for a provider like you — with clear, independently readable statements, structured data and machine-readable formats. If you're not visible here, you simply don't exist for this growing group of searchers.
