Definition
Information gain is a concept in content evaluation that measures how much new, unique information a piece of content adds compared to what already exists on the web. Google and AI systems prioritize content that provides novel value, not just rephrases existing content.
Why It Matters
Content that simply rephrases what's already available provides low information gain and is less likely to be retrieved or recommended by AI systems. Content with original data, unique insights, proprietary research, or original analysis provides high information gain and is prioritized.
Examples
- An article that cites original survey data about dental patient satisfaction → high information gain
- An article that rephrases the same 10 tips already on WebMD → low information gain
