ROAS Optimization for Rewarded User Acquisition Campaigns
ROAS vs CPI
CPI (Cost Per Install) tells you what an install costs. ROAS (Return on Ad Spend) tells you what an install is worth. A $2 CPI with $10 LTV (5x ROAS) is excellent. A $0.50 CPI with $0.25 LTV (0.5x ROAS) is a loss. Always optimize for ROAS, not just CPI.
Rewarded UA ROAS Benchmarks
Rewarded UA typically delivers: D7 ROAS: 15-40% (target: 30%+), D30 ROAS: 50-120% (target: 100%+), D90 ROAS: 100-300% (target: 200%+). These are higher than traditional UA because rewarded users have higher intent.
Optimization Strategies
1. Segment by Offer Type: Some offers produce higher-LTV users. Track ROAS per offer and allocate more budget to top performers.
2. Creative Testing: Test different offerwall placements and reward messaging. A/B test reward amounts.
3. Geo Optimization: eCPM and CPI vary dramatically by country. Allocate budget to countries with the best ROAS, not just the cheapest CPI.
4. Post-Install Events: Optimize beyond install — track D1 retention, D7 retention, first IAP, and LTV.
