    Why llms.txt Matters for Your Business

    AI Search is Here

    ChatGPT, Claude, and Perplexity are replacing traditional search for millions of users. If they can't find your content, you're invisible.

    llms.txt is the Standard

    The llmstxt.org specification tells AI systems exactly what your site offers and which pages matter most.

    Early Adopter Advantage

    Less than 1% of websites have a proper llms.txt file. Set yours up now and be discoverable before your competitors.
