In IAA (In-App Advertising) games, eCPM (effective cost per mille) is one of the most important revenue metrics. It tells you how much you earn per 1,000 ad impressions—and ultimately determines your ARPU and ROI. But many developers focus only on ad volume, ignoring the potential of eCPM optimization.
Here’s how to systematically boost your eCPM through ad strategy, user segmentation, and platform setup.
1. Choose the Right Ad Format
Each ad type delivers a different eCPM. Beginners should prioritize high-ROI formats first:
Ad Type | Avg eCPM (e.g., SEA region) | Tips |
---|---|---|
Rewarded Video | High ($8–15) | Use voluntary triggers in gameplay |
Interstitial Ads | Medium-High ($5–10) | Show during natural breaks |
Banner Ads | Low ($0.5–2) | Use sparingly, not for core monetization |
📌 Tip: Don’t use all ad types at once. Start with rewarded video, then experiment with interstitials. Use banners only when it makes sense.
2. Improve Ad Quality to Get Better Rates
eCPM isn’t about how many ads you show—it’s about how well they perform. Optimize these key areas:
-
Clear & Valuable Rewards
Avoid vague messaging. Tell users exactly what they’ll get—e.g., “Watch to earn 500 coins.” -
Smart Timing
Trigger ads after failure, during cooldowns, or for optional boosts—not during core gameplay. -
Avoid Fatigue
Set limits (e.g., 5 rewarded ads per day) to prevent user churn and increase value per view.
3. Segment Users by Behavior
Not all users generate the same revenue. Segmenting users lets you tailor ad strategies to maximize value:
User Segment | Behavior Traits | Monetization Strategy |
---|---|---|
High Retention | Plays often, engaged | Show more rewarded ads, offer bonuses |
Low Retention | Leaves on Day 1 | Show interstitials early for quick ROI |
High Potential | Deep engagement, pays attention | Reduce ad frequency to not cannibalize IAPs |
SolarEngine supports user segmentation and ad return analysis, helping developers target high-LTV audiences and apply differentiated monetization tactics.
4. Choose the Right Ad Network & Mediation Setup
eCPM varies widely between ad platforms. Using multiple networks via mediation ensures higher fill rates and maximizes competition for each impression.
Comparison of major platforms (for rewarded video):
Platform | Strong Regions | eCPM Stability | Role |
---|---|---|---|
AdMob | US, JP, KR, EU | High | Main platform |
ironSource | North America, East Asia | Medium-High | Supports rich video delivery |
Mintegral | SEA, MENA, LATAM | Medium-High | Good for cost-efficient scaling |
📌 Use a mediation tool (AdMob, ironSource, TradPlus) to connect 3–4 ad sources and set eCPM floors to avoid low-paying inventory.
5. A/B Test Constantly—Don’t “Set and Forget”
Monetization is not a one-time setup. Use A/B tests to find your best-performing strategy:
-
Reward Type: Coins vs. power-ups
-
Ad Frequency: After every level vs. every two levels
-
Button Design: Placement, size, call-to-action copy
Pair with data visualization to track trends and iterate continuously.
Conclusion: eCPM Is a Team Effort Across Design, Data, and Strategy
Improving eCPM isn’t just about showing more ads—it’s about showing the right ads, to the right users, at the right time, on the right platform. A smart monetization system starts with good fundamentals and improves through iteration.
