The Secret to Higher Rankings in the App Stores
There's a lot of speculation about what goes into the ranking algorithms for the Apple App Store and Google Play: Keywords in the title, keywords in the landing page, download count, installs, rating and review sentiment, retention, revenue, etc. etc..
What's missing from a lot of this speculation is the number of ratings and reviews an app has. More than the star rating itself, the rating count seems to be what separates the top chart apps from the other 1.3 million apps:
- The top 100 Android apps average 3.1 M ratings each while the top 100 iOS apps average 196 k ratings.
- Apps in the 401-500 ranks (still in the 99.96 percentile of all apps) have "only" between 10% (Android) and 20% (iOS) of the rating volume of those apps in the top 100.
- Two-thirds of all other apps haven't received a single rating.
I ran some experiments on app store data this morning, testing a multitude of factors commonly thought to be predictors of rank. Among these, the strongest correlation was between rating count and ranking, with a 40% correlation:
And here's the same chart for apps ranked lower on the top chart (note the dramatic difference in the scale of the y-axis):
Apps with more ratings also tend to have less volatile rankings, making it easier to stake a claim in the top charts:
Clearly, rating count matters.
