What is App Store Optimization (ASO)?

Definition

App Store Optimization (ASO) is the process of improving an app’s visibility and conversion in the App Store and Google Play, so more people find it and install it.

The two halves of ASO

  1. Visibility — being found. Ranking for relevant searches and in category charts. Driven by your title, subtitle and app store keywords, downloads, and ratings.
  2. Conversion — being chosen. Turning page views into installs. Driven by icon, screenshots, app rating and reviews. Measured as app store conversion rate.

Main ASO factors

Example

Incorporating high-traffic keywords into your app title and description improves your app's ranking; testing a new first screenshot that shows the main benefit instead of the login screen raises conversion.
