Keyword Cannibalization

Keyword cannibalization in ASO happens when you repeat the same word across multiple metadata fields — for instance, putting “fitness” in your title, subtitle, and keyword field. On the App Store, a term only needs to appear once to be fully indexed, so each repeat is a wasted slot that could have covered a different keyword.

The cost is opportunity: every duplicated word is a keyword you’re not ranking for. With only ~100 characters in the keyword field plus the title and subtitle, breadth is precious.

Audit your metadata as a single combined keyword set, eliminate duplicates, and spend the recovered space on additional relevant terms.
