You ran your site through PageSpeed Insights, and something unfamiliar appeared in the report: a line about a file named llms.txt . Your site doesn’t have one. Is that a problem? You go looking and land on Google’s own Search documentation, which says you don’t need one to appear in Google Search, including its AI features.

Both of those are coming from Google. Confused?

Why it matters: One part of Google documents a file that can help AI agents. Another says it isn’t needed for Search. Before you install a plugin or write it off, it’s worth ten minutes to understand which answer applies to your site.

It isn’t a contradiction. Once you see where each answer comes from, you’ll know whether your site needs one.
