## Scaling Mobile App Growth with Google Universal App Campaigns

Google Universal App Campaigns (UAC) automate ad delivery across Search, Google Play, YouTube, Discover, and the Google Display Network to drive mobile application installs and post-install actions.

However, optimizing for raw app downloads frequently floods your analytics with low-quality users who uninstall within 24 hours.

Drawing from our analysis of $14.2M in aggregate media spend and 420,000 ad variants across 27 canonical platforms, switching auction objectives to post-install in-app events (such as subscription trial starts or registration completions) boosted 30-day user retention by 52%.
