What is Information Gain?
Information Gain is the score from Google's 2022 patent: how much 'new information' a page adds relative to already-indexed content. Generic rewrites score near 0; first-party data, exclusive cases, and original experiments score high and rank first.
How do you apply it in practice?
Practice: every new piece needs an Information Gain Plan — explicitly state 'what you add vs the current top 10'.
Why does it matter for AI search citations?
Generative search engines tend to extract sentences that are clearly defined, consistent and quotable on their own. Writing concepts like "Information Gain" as one consistent definition across your site, backed by structured data and verifiable sources, lowers the chance of being misread. This improves readiness only; it does not guarantee citations or ranking gains — measure actual citations to know.
What are the common misconceptions?
- Information Gain ≠ longer word count — an exclusive paragraph beats a diluted long post
- AI paraphrasing scores 0 and can trigger Helpful Content demotion
