llms.txt for AI Discoverability: Should You Add It?

Short summary

llms.txt is a proposed Markdown standard for AI discoverability that lets you place a structured site description at yourdomain.com/llms.txt. No major AI provider currently supports it, but the 15-minute implementation effort is asymmetrically justified by potential future benefit across training crawls, runtime AI systems, and autonomous agents. The strategic question is whether early adoption will compound into advantage if platforms eventually commit to the standard.

• •llms.txt is a community-proposed standard (not yet officially adopted) for describing your site and key pages to AI systems in structured Markdown
• •Three AI access patterns could benefit: base model training crawls, runtime inference systems (Perplexity, Bing Copilot), and autonomous web agents
• •Current support is zero, but minimal implementation cost makes early adoption an asymmetric bet for potential multi-year compounding benefit
