How do we calculate it?
The Visibility Score is based on search volumes and keyword rankings. Apple and Google do not disclose the exact traffic numbers on keywords, so we use this KPI to track how ASO activities affect the app's visibility.
For the App Store, we directly use Apple’s Popularity Score wherever we can, since we have already discovered that there is a direct correlation between impressions and keyword popularity. (Apple only provides these scores for Apple Ads countries.) For the remaining countries, we use our own algorithm to estimate search volumes.
For the Google Play Store, we use our own algorithm to estimate search volumes.
What is the methodology?
We get the top-ranking keywords for every app in both stores. Then we calculate each app's potential impression share on each of these keywords and scale them according to their search volume. This is a country specific score between 0-100, meaning that the most visible app in a selected country is given the score 100. Other apps are scaled accordingly with an exponential scaling method.
How often is the data updated?
We update visibility score estimations daily.
What is the data coverage?
We cover both the Google Play Store and the App Store.
