Keyword Cannibalization
Search terms where two or more of a developer’s own apps land in the same result. Each app’s keyword report looks fine on its own — the overlap only shows up once you put the whole portfolio next to one live search.
What this answers
Once a developer ships a second app, the two listings start appearing in the same searches — sometimes deliberately, often not. No single app’s keyword report can show this, because each one only ever looks at itself. This loads the whole portfolio, derives search terms from its own app names and categories, and reports the terms where two or more of those apps come back in one live result, with each position.
Want the portfolio numbers instead — downloads, revenue and ratings per app? Publisher portfolios covers that side.
