Since the inception of the Google Play the question - how does this app store operate (read: how does it rank apps) was the number one. This week we can that say that, at least partly, this question was addressed, during the last week Google’s I / O Google Play Ankit Jain did provide a great insight into how Google Play works. Quite frankly this is the priceless information for any Android app developer. In a nutshell here is the scope of what was revealed: 12% of DAU (daily active users) search for apps daily 50% of DAU search for apps weekly 6 million unique search phrases being searched monthly and roughly 50% of those are misspelled words! An app’s title should reflect it’s purpose, be short, unique and creative. The first app’s description sentence should give a clear picture of what app is about Screenshots and video are the crucial ingredients to entice people to download an app There are device and geo targeting in place for reviews and ratings Jain highly recommends that developers with a tablet app get the “designed for tablets” designation. Make sure your app’s page on Google Play are getting links with targeted keywords in its anchor text and it sounds enticing in general. Don’t imitate an existing popular app’s name and again - remember about all those 50% of monthly search queries that are essentially misspelled words. Keep your app package (APK) small - small apps are getting more installs. Create the viral loop for your app: A. Get users to review your apps. B. Don’t get users to leave your app. This can be accomplished by adding an in-app Google+ +1 API, and in the future, Google will release an API for in-app user reviews. C. Integrate Google Play’s newly launched game services.
