App Store Sources
With App Analytics, you can see how many users discover your app while searching or browsing the App Store — including tapping on Search Ads for your app — to gain insight into how your marketing and metadata impact downloads.
App Analytics counts users who visit your app’s product page from a link within another app. Optimize your marketing campaigns by focusing on the apps that drive the most App Store impressions, downloads, and billings.
