llms.txt guide

llms.txt is a markdown file at your site root that tells AI crawlers which pages matter and how they may use your content. It acts as a curated map, helping models find citable sources without wasting context on noise. Think of it as robots.txt for the generative era, but for discovery and citation rather than crawl control.

Why does llms.txt matter?

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 should you 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
