Best practices
Keep it concise
Focus on your most important pages. AI systems work best with clear, structured content — not an exhaustive list of every URL.
Write clear descriptions
Each link should have a description that explains what the page is about, not just what it's called. Help AI understand the content.
Update when your site changes
New pages, removed content, or restructured sections should be reflected in your llms.txt. Regenerate periodically to stay current.
Organize by priority
Put your most important pages in a "Core Resources" section. Secondary content goes under "Optional." AI systems respect this hierarchy.
