What is llms.txt and why does it matter for AEO?

llms.txt is a plain-text file at the root of your domain that gives large language models a curated, machine-readable summary of your brand, products, definitions, and citation-eligible pages — like a sitemap, but written for LLM consumption.

Step by step

1. Step 1

   Where it lives

   /llms.txt at your domain root, served as text/plain.

2. Step 2

   What it contains

   Canonical brand facts, definitions you want quoted verbatim, pricing, supported integrations, and a curated list of citation-eligible URLs.

3. Step 3

   llms-full.txt

   An optional longer variant with the full text of high-value pages, so models that ingest it can answer without re-crawling.

4. Step 4

   Why it matters

   It lets you control the version of your brand that LLMs quote, instead of hoping they assemble the right facts from random subpages.
