Qu'est-ce que App Store Optimization ?

App Store Optimization goes beyond simple keyword stuffing. It is a multi-faceted discipline that touches every aspect of your app's presence in the store. The process begins with market research to understand your target audience, their search behavior, and the competitive landscape in your category.

On the discoverability side, App Store Optimization involves choosing the right primary category, crafting a keyword-rich title that stays under the 30-character limit (iOS) or 50-character limit (Google Play), writing a compelling subtitle, and filling the keyword field with high-volume terms that are not already in your title. On Google Play, the long description is indexed, so natural keyword integration matters.

On the conversion side, your first three screenshots carry the most weight since they appear in search results without tapping into your listing. A/B testing different screenshot designs, captions, and ordering can dramatically improve your tap-through rate. Your app icon is the single most-seen creative asset — it appears in every search result, chart, and notification. Ratings above 4.0 are a psychological threshold that significantly impacts download decisions.
