Information Gain
A concept from a Google patent describing how search results may be scored by how much new information a document adds relative to pages the user has already seen on the same query. The practical implication is that publishing another near-identical guide on a saturated topic adds little value; pages that introduce original data, a novel framing, or a unique perspective earn stronger rankings and more AI-answer citations.
How Information Gain works in practice
Google’s information-gain patent describes a ranking adjustment that scores documents by how much new information they contribute relative to what the user has already seen, reducing redundancy in the result set. The strategic consequence is that publishing another well-optimised but derivative guide on a saturated topic now returns less than it used to — the tenth article explaining the same framework earns diminishing traction regardless of on-page technicals. Content that wins under information-gain tends to have one of: original research or proprietary data, a novel synthesis of known ideas, a strong author perspective, or a practical angle (templates, calculators, worked examples) that competing pages lack. The same principle is amplified in AI answer engines, which explicitly reward citing sources that add something distinct rather than echoing the consensus.
