Portfolio Keyword Cannibalization
Portfolio keyword cannibalization happens when a studio's multiple apps target the same keywords, splitting the same search demand between the studio's own apps instead of capturing a wider set of terms.
This is a different problem from single-app keyword cannibalization, where one app repeats a term across its own title, subtitle, and keyword field. Here, two or more apps from the same developer both target 'habit tracker', for example, and end up competing against each other in the same search results — capping how much combined visibility the studio gets from that one term.
It shows up most in studios that build several apps in the same category, or that clone a successful app's metadata pattern for a new release without checking for overlap. The studio's total keyword footprint ends up narrower than the sum of two apps' character budgets should allow.
The fix is treating keyword assignment as a portfolio decision, not a per-app one: score the studio's full candidate list once, then split it so each app owns distinct, non-overlapping terms rather than defaulting every app to the same obvious category words.
Frequently asked questions
- How do I check whether my own apps are cannibalizing each other?
- Run each app's current keyword set through the same scoring pass and compare the lists side by side. Overlapping high-value terms across apps in the same category are the candidates to redistribute.
- Should sister apps ever share a keyword on purpose?
- Occasionally, for a term core to the studio's brand identity across its apps. But treat that as a deliberate exception, not the default outcome of not checking for overlap.
