Google today announced it's rolling out a change to its Play Store so that better-performing apps -- meaning those that experience fewer crashes and those that don't drain your smartphone battery -- will be ranked higher than apps with bugs and other performance issues. From a report: The goal with this new ranking algorithm is to ensure that the best apps are being promoted, which in turn leads to increased app usage and engagement, the company says. The impetus for this change came after Google realized that around half of the 1-star reviews on the Google Play Store were about app stability problems. Apps that don't work well frustrate users, who often turn to the reviews to leave a complaint. Over time, a number of bad reviews and low star ratings can impact the app's place in the charts and search results. But if an app is popular enough, a large number of installs can still, to some extent, override its negative reviews and push the app back up into a higher position than it rightly deserves.
