Search Popularity is a metric that indicates how often a particular keyword or search term is entered by App Store users. The popularity level is shown as a number between 1 and 5, with 5 representing terms that see the highest search volume. This gives insights into which keywords are most commonly used by consumers to search for apps like yours organically. Factoring search popularity into keyword bid management allows focusing media budgets on the terms most likely to generate impressions and downloads. Targeting popular searches maximizes visibility and chances of a user finding your app listing.
