Should I Use llms.txt on My Website?
You should use llms.txt only if you will keep a small, accurate file at your site root that points models to canonical pages and policies. It does not replace SEO, AEO, or a sitemap. Skip it if you cannot assign an owner to update it when URLs change.
Key takeaways
- llms.txt is curated guidance for models; sitemaps list URLs for crawlers.
- Stale llms.txt hurts more than missing llms.txt when models follow bad links.
- Fix answer-shaped HTML and entity consistency before you obsess over the file.
- Assign the same owner who updates sitemaps after service page renames.
What is llms.txt?
llms.txt is a plain-text convention: a file at /llms.txt that lists important URLs, optional notes, and sometimes contact or licensing hints for language models. It is not an official search standard. Think of it as a readme for bots.
What does llms.txt do?
It suggests where to look first on your site. Models may or may not fetch it. When they do, a stale file hurts you by pointing to retired pages.
Does llms.txt work?
Sometimes models respect it; sometimes they ignore it. Evidence is anecdotal, not a published guarantee. Treat any traffic lift as unproven unless you measure your own buyer questions over time.
Should I use llms txt if I already have a sitemap?
Yes, only as a supplement. Sitemaps list URLs for crawlers. llms.txt is curated guidance for models. Most small businesses get more from fixing on-page answers than from either file alone.
How to add llms.txt in WordPress or Shopify
Publish a static text file at the domain root, or serve it through your host’s static file rules. Keep it under a few dozen lines: company name, primary service URLs, contact, privacy, and any pages you want quoted. Update the file the same day you rename or merge pages.
Do not paste secrets, unpublished pricing, or client-only links.
How llms.txt fits AEO
Answer engine optimization (AEO) still depends on citable HTML, entity consistency, and proof. llms.txt is a minor signal. Prioritize the full agent-ready website checklist and how answer engine optimization relates to SEO first.
We cover discoverability files as part of our AEO website build, including discoverability files when clients want them maintained.
Questions we get

Can llms.txt hurt SEO?
Not directly. A misleading file can send models to wrong URLs, which hurts your brand in answers.
Do I need a llms.txt generator?
Generators help draft the first version. A human must verify every URL and remove duplicates.
Is llms.txt required for ChatGPT?
No. ChatGPT recommendations follow verifiable public content, not a single config file.
Who should own maintenance?
Whoever owns the sitemap and service page renames, usually marketing ops or whoever ships site changes.
