The amount of new, unique value a page adds beyond what already exists in the search results for a query.
Information gain measures how much a page contributes that the existing top results do not - original data, first-hand experience, a novel framing, or a genuinely better explanation. Search engines and AI systems increasingly reward distinctiveness over repetition, so content that merely restates the consensus struggles to rank or be cited. Prioritising information gain shifts content strategy from matching competitors to surpassing them, and it is a core reason original research and expert insight outperform commodity content.
