LLMs.txt Resources & Guide

Everything you need to know about implementing and optimizing llms.txt files for AI discovery

What is LLMs.txt?

LLMs.txt is a proposed standard introduced by Jeremy Howard in September 2024. It's a text/Markdown file placed at the root of your website (e.g., example.com/llms.txt) that provides structured information about your site specifically for AI systems and Large Language Models.

Unlike robots.txt which tells crawlers what NOT to access, llms.txt acts as a guide showing AI systems the BEST content to understand your site. It's like a curated map of your most important pages and information.

The file uses Markdown formatting and should include your company description, key pages, products/services, and any other information you want AI systems to know about.

Why LLMs.txt Matters

  • ✓
    AI-First Discovery: As users increasingly rely on AI assistants like ChatGPT and Claude for information, having an llms.txt ensures your content is properly understood and cited.
  • ✓
    Better Context for AI: Provides structured, relevant information that helps AI models give accurate answers about your business.
  • ✓
    Future-Proof SEO (GEO): Generative Engine Optimization is the next frontier. Early adoption positions you ahead of competitors.
  • ✓
    Control Your Narrative: You decide what information AI systems prioritize about your organization.

Current Adoption Status

As of 2025, llms.txt is still an emerging standard:

  • • Major AI providers (OpenAI, Google, Anthropic) haven't officially integrated support yet
  • • Anthropic has published their own llms.txt, showing interest
  • • You must manually provide the file to AI systems currently
  • • Early adoption gives you a competitive advantage

Common Mistakes to Avoid

❌ Too Generic or Vague

Don't just list page titles. Provide context about what makes your content valuable and unique.

❌ Outdated Information

Broken links or outdated product info can hurt AI understanding. Keep content current.

❌ Overly Complex Structure

While comprehensive is good, avoid over-complicating. AI systems prefer clear, logical organization.

❌ Missing Key Context

Don't assume AI knows your industry. Provide context about your business model, target audience, and unique value.
