Best Practices for llms.txt

Do This

  • Use single H1 heading for your business name (required)
  • Include blockquote mission statement right after H1
  • Organize content with clear H2 sections (What We Do, Services, Contact)
  • Include contact information (email, phone, website, social media)
  • Add links to key pages (documentation, blog, support, pricing)
  • Update quarterly with new offerings, achievements, or changes
  • Keep file under 10KB for fast loading (most templates are 2-5KB)
  • Use Markdown formatting consistently throughout

Avoid This

  • Don't use multiple H1 headings (confuses AI models)
  • Don't skip the mission statement blockquote (loses 10 points)
  • Don't use HTML tags (stick to pure Markdown syntax)
  • Don't include sensitive data (passwords, API keys, private info)
  • Don't copy competitors' llms.txt word-for-word (AI detects duplicates)
  • Don't use generic templates without customization
  • Don't include broken links (validator will flag them)
  • Don't forget to upload to website root (not in subdirectory)
