Think of llms.txt as a guide for AI, just as robots.txt is a guide for search engines.
While robots.txt tells crawlers what they can index, llms.txt tells AI models how to understand and reference your site.
As AI-powered search tools like ChatGPT, Perplexity, OpenClaw, and Google AI Overviews grow in popularity, adding an llms.txt file ensures your site is recognized and cited in AI-generated responses.
