What is Information Gain in SEO?
Information gain is the idea that content is rewarded for adding information not already available elsewhere. If your page says what every other page says, it adds nothing. If it contributes unique data, it wins.
Why it matters now
As AI models summarize the web, they favor content that contributes something new. Redundant content is ignored.
How to increase information gain
Publish proprietary data, original research, expert quotes, and unique comparisons that cannot be found on competitor pages.
The GEO link
Generative engines explicitly favor high-information-gain content because it is what makes their answers better than a simple summary.
