The Store Rank is a metric directly extracted from Google Play or Apple’s App Store.
The Store Rank is based on multiple parameters set by Google and Apple. Experts suggest that their store ranks factor in metrics like: total downloads, recency of downloads, reviews, uninstalls, user experience, in-app revenues and more.
Using this metric
The higher the app is ranked, the higher visibility the app has on Google Play Store and Apple’s App Store. Use this metric to assess the likelihood of users to install the app.
