Providing users with safe and secure experiences, while helping developers build and grow quality app businesses, is our top priority at Google Play. And we’re constantly working to improve our protections.
Google Play has been working to minimize app install attribution fraud for several years. In 2017 Google Play made available the Google Play Install Referrer API, which allows ad attribution providers, publishers and advertisers to determine which referrer was responsible for sending the user to Google Play for a given app install. This API was specifically designed to be resistant to install attribution fraud and we strongly encourage attribution providers, advertisers and publishers to insist on this standard of proof when measuring app install ads. Users, developers, advertisers and ad networks all benefit from a transparent, fair system.
We also take reports of questionable activity very seriously. If an app violates our Google Play Developer policies, we take action. That’s why we began our own independent investigation after we received reports of apps on Google Play accused of conducting app install attribution abuse by falsely claiming credit for newly installed apps to collect the download bounty from that app’s developer.
We now have an update regarding our ongoing investigation:
- On Monday, we removed two apps from the Play Store because our investigation discovered evidence of app install attribution abuse.
- We also discovered evidence of app install attribution abuse in 3 ad network SDKs. We have asked the impacted developers to remove those SDKs from their apps. Because we believe most of these developers were not aware of the behavior from these third-party SDKs, we have given them a short grace period to take action.
- Google Ads SDKs were not utilized for any of the abusive behaviors mentioned above.
- Our investigation is ongoing and additional reviews of other apps and third party SDKs are still underway. If we find evidence of additional policy violations, we will take action.
We will continue to investigate and improve our capabilities to better detect and protect against abusive behavior and the malicious actors behind them.
