What is llms.txt and why it's revolutionizing AI SEO
llms.txt is an emerging standard for AI optimization. Just as robots.txt guides search engine crawlers, llms.txt instructs Large Language Models (LLMs) on how to understand, cite, and use your website's content. It's a simple Markdown file hosted at your domain root, acting as an "instruction manual" for AI agents.
With the rise of tools like ChatGPT, Claude, Perplexity, and Copilot, ensuring your site is read correctly and cited accurately has become as crucial as traditional Google SEO. llms.txt centralizes documentation, API links, social profiles, and usage guidelines in a format LLMs process efficiently.

Difference between robots.txt and llms.txt
While robots.txt focuses on blocking or allowing crawling (indexing), llms.txt focuses on teaching and contextualizing (understanding). They are complementary: one controls access, the other optimizes interpretation. We recommend keeping both at your domain root for a complete technical SEO and AI SEO strategy.
