Crawlers & Access
Is llms.txt the same as robots.txt?
Updated January 12, 2026GEO Expert Team
Summary
No: robots.txt provides access control signals for crawlers (allow/disallow). llms.txt provides curated 'how to use this site' context for LLMs/agents. They're complementary standards for different purposes.
Detailed Answer
No:
robots.txt:
- Purpose: Access control signals for crawlers
- Function: Allow/disallow crawling paths
- Audience: All crawlers (search, AI, etc.)
llms.txt:
- Purpose: Curated "how to use this site" context
- Function: Guide LLMs to key resources
- Audience: AI assistants at inference time
Key difference:
- robots.txt = "What can you access?"
- llms.txt = "What should you focus on?"
The proposal explicitly positions llms.txt as complementary to existing standards like robots.txt and sitemap.xml. Use both for complete AI optimization.
