llms.txt guide

llms.txt is a markdown file that tells AI crawlers which pages are worth reading and how they may use your content. It is the robots.txt for the generative era.

Why llms.txt matters

AI crawlers have limited context windows. A good llms.txt points them to your most important, citable pages instead of letting them wander through policy docs and duplicate content.

What to include

  • ✓ A short summary of your site and brand
  • ✓ Primary URLs with markdown links
  • ✓ Core topics you want to be known for
  • ✓ Usage preference (search, citation, no training)
  • ✓ Optional: paths to exclude

Best practices

  • ✓ Keep it under 100 lines
  • ✓ Use real markdown links, not plain URLs
  • ✓ Update it when you add key pages
  • ✓ Serve it at /llms.txt
  • ✓ Link to it from your homepage or footer
