llms.txt adoption
llms.txt is a proposed convention: a markdown file at /llms.txt
that gives language models a curated index of a site's content. Proposed by Answer.AI in
September 2024, it is published by site owners in the hope that AI systems read it.

Where this standard actually stands
No major AI crawler operator has committed to reading llms.txt, and Google has said publicly that its systems do not use it, comparing it to the old keywords meta tag. Publishing one is currently a signal of intent, not a control. We count files because adoption itself is worth tracking; we make no claim that the files are being read.
Our count includes every domain that answers with a file
at /llms.txt. Some of those responses are empty or boilerplate, so treat the
total as an upper bound on deliberate adoption.
Counting method and definitions are on the methodology page.
