The llms.txt Specification & Implementation Manual

The /llms.txt standard provides LLMs with a clean, unstyled Markdown file detailing your brand's core facts, avoiding DOM parsing errors and rate limits.

Best Practices for llms.txt

• Keep it under 300 words: High token density ensures models read the full file in a single context window.
• Include Canonical URLs: Always use absolute HTTPS links to core service landing pages.
• Explicit Value Propositions: Use declarative sentences describing what you do and who you serve.
