A primer on llms.txt
A small file
at the root
of your site,
read by every
major LLM.
LLMs can't recommend what they can't parse. The small file at the root of your site — llms.txt — is the first step to making your site known.
No AI ranking guarantees. No magic SEO claims. llms.txt is a metadata helper — its job is to make your site clearer to AI crawlers, not to force them to cite you.

What is llms.txt? The complete guide for site owners.
From the GEO/AEO terminology landscape to step-by-step install instructions and the misconceptions that trip site owners up. Written so a non-developer can ship it in an afternoon.
The shift
Search is becoming an answer.
A decade of SEO was about ranking among ten blue links. That world is ending. Today, more queries return a single AI-generated answer — and that answer cites two to seven sources.
Whether your site is one of them depends on something most people have never heard of: the file at /llms.txt.
Where to start
5 lines beats 0 lines.
Without an llms.txt, AI assistants parse your full HTML — navigation, scripts, cookie banners — and guess what your site is about. With even a five-line file (a one-paragraph summary and a list of your main pages), they read your site's "table of contents" in one fetch and cite it confidently.
The gap from nothing to something is far bigger than the gap from basic to perfect. Generate a rough draft today; polish it later.
