Information gain

What is information gain in AI search?

How much genuinely new information a page adds compared with everything already published on the topic. Content that only restates what ten other pages say gives a model no reason to cite it; proprietary data and a unique angle do.

Retrieval systems deduplicate aggressively. If your page repeats the consensus, the model already has that sentence from a source it trusts more, so your version adds nothing and gets dropped.

Information gain is why MyFast.ai asks every client for proprietary numbers, internal benchmarks and real operating detail during onboarding. A figure only you can publish is the one sentence in the article that cannot be sourced anywhere else.
