How do I lower cost per paying user, not just cost per install?
Cheap installs that never pay make ad reports look good and revenue look bad.
- Our cost per install is low but revenue is flat.
- Which channel brings payers?
- What should ads optimize for?
Send trial starts and purchases back to your ad platforms, through an attribution or analytics tool, so campaigns optimize for paying users, not installs. Compare channels on cost per trial, cost per paying user and payback period. Fix onboarding and paywall conversion first, since a better funnel lowers cost per paying user on every channel.
