What Is llms.txt? A Complete Guide to Format, Required Info, and Dynamic Generation [LLMO]
If robots.txt is a file that tells search engines what they can and cannot crawl, llms.txt is a file that tells AI about your site's content and structure. It helps LLM crawlers (GPTBot, ClaudeBot, etc.) understand your site, increasing the chances of being cited in AI-powered search results. This article covers everything from the llms.txt format specification and what information to include, to whether you should use a static file or dynamic generation, and how to implement it in major frameworks.
