Why llms.txt matters

AI models are now the front door to your content. llms.txt is a Markdown file at the root of your domain that points models to the canonical pages they should read first. Without it, crawlers guess — and they often guess wrong.

What goes in it

  • An H1 with your site or product name
  • A short blockquote summary
  • A ## Docs section linking to your most important reference pages
  • An optional ## Optional section with secondary resources

After you publish

Upload to /llms.txt on your domain and run the OptimAIze scanner to confirm it's discoverable, well-formed, and actually being picked up by the AI crawlers that matter.

Want the full picture?

This tool generates one piece. OptimAIze scans your whole site, audits structured data, content, crawler access, and answer-readiness — then gives you everything you need to be cited by AI.

Frequently asked questions

What is llms.txt?
llms.txt is an emerging standard that tells AI models which pages on your site are most worth reading. It lives at the root of your domain, just like robots.txt, and is written in Markdown so LLMs can parse it easily.
Where do I put the file?
Upload it to the root of your domain so it's reachable at https://yourdomain.com/llms.txt. AI crawlers and ingestion tools will fetch it automatically.
Do ChatGPT and Perplexity actually use llms.txt?
Several AI tools and crawlers already check for it, and adoption is growing fast. Even where it isn't strictly required, publishing one helps you control how your content is summarized.
How is llms.txt different from sitemap.xml?
sitemap.xml lists every URL for search-engine indexing. llms.txt is curated for AI: it highlights the canonical pages you want models to learn from and links to long-form context.
