    The Honest Position

    There is no confirmed public statement that major search engines use llms.txt directly in ranking.

    AI referred sessions increased 527 percent between January and May 2025. ChatGPT reached 800 million weekly users in 2025.

    As AI platforms typically cite only 2 to 7 domains per response, structured clarity is becoming more relevant.

    llms.txt should be viewed as a forward looking clarity layer, not a guaranteed ranking mechanism.
