Dayzle developer finds most Google Ads app installs came from bots, not users

A solo developer running Google Ads for his puzzle app Dayzle discovered that of 56 billed installs over two weeks, only 13 were real users; the rest came from devices sideloading outdated app versions while falsely reporting Google Play as the installer. These fake installs showed zero engagement, spanned dozens of phone models across many states, and appeared to be generated by a bot farm gaming Google's install-based ad optimization.
