"By focusing on the quality and performance of your app, you'll find more success on Google Play", the company added.
Google invites developers to use the Play Console which can help find and fix a number of quality issues like excessive battery usage, slow render times or random crashes. Google has taken this step after realising that half of the one-star-scored apps on the Play Store's reviews say that they have stability problems.
"As part of our continued effort to deliver the best possible Google Play experience, we recently enhanced our search and discovery algorithms to reflect app quality", Google Play's product manager Andrew Ahn explains. The bad Android apps are those that crash a lot when they are launched and includes apps with a low user rating as well.
Another program, called Android Excellence, has been created which would curate the good apps on Google Play Store.
Now, the ranking algorithm update will force developers with buggy apps to address their issues or have penalised as a result. This particular implementation breaks down all prompts pushed by the Play Store into five categories - High Priority, App Updates Available, Updated Apps, Security and Maintenance, and Account Alerts. The Android apps are often thought of as lower-quality, and now Google is trying to change that perception.
Until this update, search results in the Play Store would prioritize popularity over support.
Another thing that Google does, is providing a number of tools to help developers optimize their applications.
The new measures combined should mean that Android users will start to find higher quality apps that are free from malware in the Google Play Store. Now Google is looking to punish those apps by making them less visible in search results, which will hurt their chances of being discovered and downloaded.
