llms.txt for online stores: what it is and a template

Updated 2026-10-16 · 7 min read · By the ProductSeen team

llms.txt is a proposal for a simple Markdown file at yourstore.com/llms.txt that tells AI models what your site is and where its most useful pages are. It's cheap to add. It's also new, and nobody should promise it will change your AI visibility on its own.

Where llms.txt comes from

The format was proposed in 2024 by Jeremy Howard of Answer.AI. The idea: websites are full of navigation, scripts and ads that make it hard for a language model to find the important content, so give models a clean, curated summary with links. A companion file, llms-full.txt, can contain fuller text.

What's known about adoption

Many developer-tool and documentation sites publish llms.txt files, and some AI tools can read them when pointed at them. What isn't publicly confirmed is whether the big AI shopping and search systems use llms.txt when choosing products. Be skeptical of anyone who says it's required or that it "ranks" you. Our honest view: it's a few minutes of work with low downside, so it's worth doing after the fundamentals (crawler access, Product schema, GTINs) are handled.

Frequently asked questions

Do ChatGPT and other assistants read llms.txt?

There's no public, confirmed commitment from the major AI companies that their shopping or search systems use llms.txt. It's a low-cost, optional convention. Treat it as a bonus, not a substitute for robots.txt access, structured data and good product pages.

Will llms.txt replace my sitemap or schema?

No. A sitemap lists URLs for crawlers and schema labels product facts. llms.txt is a short human-readable summary. They do different jobs.

Can I add llms.txt on Shopify?

Shopify doesn't let you upload arbitrary files to your store's root. Common workarounds are uploading the file in Content > Files and creating a URL redirect from /llms.txt to it, or using an app that serves the file. Test the result at yourstore.com/llms.txt.

What should I not put in llms.txt?

Anything you wouldn't publish openly: no private discount codes, internal notes, or claims you can't support.
