What is Information Gain?
Also called Added informational value
Definition
Information gain, in content planning, is the useful new understanding a page adds beyond existing material. This editorial usage is distinct from the formal mathematical concept used in statistics and machine learning.
The operation of Information Gain is explained.
A page can add value through original evidence, a clearer explanation, or decision-relevant analysis.
Google asks publishers whether their content provides additional value and originality; that does not establish a public, universal information-gain score.
The relevance of Information Gain is explained.
A SaaS migration guide adds value when it explains an overlooked failure mode and shows how to diagnose it. Rewriting common migration advice with different wording does not necessarily add new understanding.
The evaluation of Information Gain is explained.
Editorial evaluation compares a draft with its sources and competing explanations and identifies the evidence or practical insight a reader gains. An internal editorial rating is not a disclosed AI search ranking factor.

Must every page contain new research?
A page can add value through clear synthesis or a useful explanation without conducting a new study.
Is longer content automatically better?
Length alone does not establish useful additional information.
