Information gain is the genuinely useful knowledge a page adds beyond restating what the pages already ranking have said — the new entities, questions, and supporting detail that make it worth reading on its own.

What it means in RankGear
Information gain lives in the Supplemental Content prompt defaults — the guidance RankGear feeds to content generation so the output isn’t just another paraphrase of the top results. When RankGear compares the pages ranking for a query, it can see which entities, questions, and supporting concepts recur across the field. The prompt defaults use that picture to push for material a page is missing: not more repetitions of the head phrase, but the adjacent facts and angles the competitors collectively cover while an individual draft leaves them out. The idea it encodes is originality with a purpose — adding what a reader can’t already get from the pages next to yours.
How to interpret it
Treat information gain as a coverage-and-clarity goal, not a keyword-density target. The useful move is to look at what relevant competitors actually address, then add the entities, questions, and context that are genuinely missing from your draft — and stop there, rather than forcing terms in to hit a count. A page can rank for the main phrase and still trail the field on the supporting concepts that a thorough answer touches. Higher gain means you’ve closed that distance by contributing something new; it does not mean you’ve packed in more instances of the same word. Judge additions by whether they answer a real question a reader would have, not by whether they raise a density figure.
Example
You’re writing about “container gardening for apartments.” Your draft covers pot selection and watering, and it uses the phrase throughout — but the competing pages ranking for the query also discuss drainage without balcony holes, weight limits on rental balconies, and which vegetables tolerate partial shade. Those recurring entities and questions are your information gain opportunity: the draft is fluent on the main topic yet silent on the supporting concepts the field treats as part of a complete answer. Adding them, in plain language a renter can act on, is what makes the page contribute rather than echo.
Important considerations
- Information gain is about adding useful, on-intent material — new wording still has to preserve the search intent, not drift into a loosely related topic.
- Repetition, keyword stuffing, and unsupported claims do not create topical authority; padding a page with terms is the opposite of contributing new knowledge.
- The signal is drawn from comparing competitors, so it’s a comparative indicator of what a thorough answer covers — not a Google score, and covering more concepts does not by itself make a page rank.
- Prioritize gaps by reader value: an entity or question that many ranking pages address is a stronger candidate than a one-off detail that appears on a single result.
