llms.txt is a small markdown file placed at the root of a website to give AI tools a curated map of the most important pages.
It is a proposal, not a standard. No major AI vendor has confirmed that it reads the file. So treat it as a low-cost supplement, not a ranking tactic.

What it looks like
A typical file has a title, a one-line summary and sections of links with short descriptions.

Keep it short. The point is to point, not to duplicate the site.
What it does
- Gives a machine-readable summary of your most important pages.
- Provides clean descriptions that a model can quote.
- Signals which pages are canonical when you have similar content.
- Is cheap to create and maintain.
What it does not do
- It is not a ranking factor.
- It does not guarantee inclusion in AI answers.
- It does not replace crawlable HTML, internal links or schema.
- It does not fix thin or inaccurate content.
- It does not control how a model uses your pages.
If your pages are blocked, JavaScript-only or outdated, llms.txt will not rescue them.
Does any AI company use it?
There is no public confirmation from the major model providers that they read llms.txt. Some tools and crawlers may support it; most do not document it.
That makes it a bet on a convention, not a proven channel. Spend an hour on it, not a quarter.
How to write a good one
- Lead with what you do. One sentence, specific.
- Group by intent. Services, products, pricing, guides, company.
- Write real descriptions. “Inventory, billing and POS” beats “learn more”.
- Link only canonical URLs.
- Keep it under 100 links. A dump of the sitemap is not a curated map.
- Update it when pages change.
- Do not include private or gated URLs.
How it fits with the rest of your site
llms.txt sits alongside, not instead of, the files search engines already use.
| File | Audience | Purpose |
|---|---|---|
| robots.txt | Crawlers | What may be crawled |
| sitemap.xml | Search engines | Every canonical URL |
| llms.txt | AI tools that choose to read it | A short, curated map |
Keep all three consistent. If a page is canonical in the sitemap, link the same URL in llms.txt. If a page is blocked in robots.txt, do not advertise it as a key resource.
Consistency is the signal. Contradictions waste the effort and can send a crawler to a page you did not mean to promote.
Common mistakes
- Copying the sitemap into the file.
- Linking every blog post, including thin ones.
- Using marketing language with no information.
- Forgetting the file at the root.
- Letting it go stale for a year.
- Expecting it to replace technical SEO.
How to measure it
Direct attribution is hard. Options:
- Watch server logs for requests to
/llms.txt. - Use UTM parameters on links you control.
- Track branded search and AI-referral traffic separately.
- Ask new leads how they found you.
Most AI referrals arrive without a referrer, so treat the numbers as directional.
Should you bother?
Yes, if it takes an hour and your site already has clear canonical pages. It costs almost nothing and may help a crawler that supports it.
No, if you are hoping it will fix weak content, slow pages or missing schema. Those problems need real work.
FAQ
Is llms.txt an official standard?
No. It is a proposed convention. Adoption is limited and vendor support is not publicly confirmed.
Where should the file go?
At the root of the domain: https://example.com/llms.txt.
Does it improve AI rankings?
There is no evidence that it is a ranking factor. It may help tools that choose to read it.
Should I remove my sitemap?
No. Keep the sitemap for search engines and use llms.txt as a separate, curated summary.
