Honest take

Does llms.txt actually do anything? Google says no.

It costs ten minutes to ship and it cannot hurt. But it is not a visibility lever, the evidence is increasingly clear on that, and anyone selling it as one is overselling.

The short answer

As of mid 2026, no major AI engine has confirmed it uses llms.txt for ranking or visibility, Google calls it speculative, and studies show the files are almost never fetched. Ship one because it is cheap and tidy, not because it will get you recommended.

97%

of llms.txt files are never fetched by an AI crawler (Ahrefs, 137,000 sites)

We have a free llms.txt generator, and we still wrote this. That should tell you we are not here to hype the file. We are here to tell you what it does, what it does not, and why it is still worth ten minutes.

Quick recap, since we covered the basics elsewhere. An llms.txt is a plain-text file at your site root that names your site, summarizes what you do, and links the pages you most want models to read. Think of it as a polite table of contents aimed at AI. The idea is reasonable. The question is whether anything actually reads it.

What the evidence says

Not much reads it, and the platforms have been blunt about ranking. The honest state of play in 2026:

An emerging convention is not the same as a ranking signal. llms.txt is the former, and the marketing around it keeps pretending it is the latter.

So should you ship one?

Yes, with the right expectations. It takes about ten minutes, and the worst case is that nothing ever reads it. The upside is a clean, model-friendly summary of your site that is genuinely useful to have written down somewhere. If adoption grows, you are ready. If it does not, you have lost nothing. Just do not file it under things that will get me recommended, because today it is not that.

The tell for an overhyped AEO tactic is a confident promise with no platform behind it. llms.txt is the current example. Ship it as good hygiene, the same way you keep a tidy sitemap, and put your real effort where the evidence actually points.

What to do instead

If your goal is to actually get read and recommended, the levers that move are unglamorous and well established. Make sure AI crawlers are not blocked in your robots.txt. Make sure your real content ships in the raw HTML, not after JavaScript runs. Add clean schema so your entity is easy to parse. Then earn the third-party mentions and reviews that these models weigh far more heavily than any file you place on your own root.

Our free tools cover the first three in a couple of minutes each, including the llms.txt generator if you do want the tidy version. Just spend the bulk of your time on the parts with evidence behind them.

Questions

If it does nothing, why does a tool check for it?

Because it is easy to check and it signals tidiness, not because the platforms reward it. A green checkmark for having the file is not the same as a ranking benefit. Treat the check as hygiene, the way a linter flags a missing alt attribute, not as a visibility score.

Could llms.txt matter more in the future?

Possibly, which is the honest case for shipping one now. Conventions sometimes get adopted. If that happens, you are already set up. But betting effort on a future that has not arrived, while platforms call it speculative, is not a strategy.

Is there any downside to publishing one?

Almost none, as long as you do not treat it as a substitute for the real work. The only real risk is opportunity cost: time spent polishing a file nobody fetches is time not spent on crawlability, structure, and third-party presence, which do move the needle.

What is the difference between llms.txt and robots.txt?

robots.txt controls access, telling crawlers what they may fetch. llms.txt is about meaning, summarizing your site and pointing to key pages. robots.txt is widely honored and consequential. llms.txt is an emerging convention that is, for now, mostly ignored.
