The Play Store contains the largest catalog of apps in the world. As our users
make decisions about the apps they’d like to install, we want to ensure Play
provides a trustworthy experience.
Recently, we announced
our improvements in fighting fraudulent and spam app installs. In continuing our
efforts to combat spammy behavior, we’ve also improved the ways we identify and
remove fake reviews and ratings. With this enhanced capability we are now able
to identify and remove more fake reviews and ratings with greater accuracy.
In the vast majority of cases, no action is needed. If you are working with
someone else to promote your app (e.g., third-party marketing agencies), we
advise you to check-in and ensure that their promotion techniques use legitimate
practices, and adhere to the Google
Play Developer Policy. The basic rule of thumb for reviews and ratings is
that they should come from genuine users, and developers should not attempt to
manipulate them in any form (e.g., fake, paid, incentivized).
We will continue making such enhancements to our systems that will further help
protect the integrity of Google Play, our developer community, and ultimately
our end users.
