    What is Information gain?

    Information gain is how much new information a page adds beyond what's already published on the topic.

    Original data, first-hand experience and clear opinions add information gain; rewriting existing articles doesn't.

    Why it matters for your business

    Pages that add something new, such as original data or real experience, give AI systems a reason to cite you instead of the many pages that repeat each other.

    Myth

    Rewording a competitor's article adds value.

    Reality

    It adds nothing new, so it gives readers and machines no reason to prefer it.

    What to do about it

    • Share anonymised numbers from your own work.
    • Explain how you do things, not just what to do.
