ContentNovel information
Information gain
The amount of genuinely new information a document adds beyond what the user has already seen in other results for the same query.
In full
The term entered SEO vocabulary via a Google patent describing scoring documents for additional information relative to those already presented. Whether or not that specific mechanism is live, the principle is directly useful: a page that only restates the consensus of the top ten results gives a search engine no reason to add it, and gives a generative system nothing distinct to cite. Original data, first-hand testing, expert interviews and unique synthesis are the practical sources of gain.
Example
A review adds bench measurements no other outlet publishes, which competitors then cite — a citable, non-commodity contribution.
