App Store Optimization is the process of optimizing a mobile app page in stores.

Helps solve three global challenges:

  • Enhances the position of the app in the issue
  • Generates user loyalty
  • Efficiently talks about the features of the application

The higher the app is located in the issue, the more potential users and buyers will see it and install it.

Main factors:
1. Position in the issue
2. TTR — conversion from issue to tap
3. CR (CTI) — conversion from click to installation


Technically, the position in the issue is influenced by:

  • Total number of application installations in a particular country
  • Number of application installations by a specific key word
  • Retention Rate – customer retention rate
  • Application rating
