    Does llms.txt help AEO?

    llms.txt is a proposed markdown file at the root of a site that summarizes it for AI models. It is cheap to add and easy to keep current. In our scoring it carries zero citation weight, because AI bots rarely request it: roughly 0.1% of AI bot requests.

    How we score it

    We keep llms.txt as a check in every diagnosis and give it zero citation weight. Fixing the live fetch on your real pages matters far more.

    Questions people ask

    Should I add llms.txt?

    It does no harm and takes minutes. Do it after your key pages pass the live fetch, not instead.
