Built into thousands of apps, AdMob connects publishers with Google’s global ad network, enabling competitive eCPMs and strong fill rates across regions and device types.

Getting Started with AdMob Integration
Implementing AdMob begins with creating a project in the Google AdMob UI, adding your app, and placing ad units where they perform best without harming UX.
Use the official SDKs for Android and iOS, follow integration best practices, and test with sample ad units before going live with real ads.
Ad Formats and Monetization Strategies
Banner and Interstitial Ads
Banner ads provide steady incremental revenue, while interstitial ads work well between natural breaks in app flow, such as after a level completes.
Rewarded and Offerwall Ads
Rewarded video ads drive higher eCPM because users opt in to watch for in‑app rewards, and offerwall campaigns can further boost incentive revenue in certain verticals.
Optimization and Experimentation
Run A/B tests on ad density, frequency capping, and mediation waterfall settings to find the balance between revenue and retention.
Leverage machine‑learning‑based fill optimization and smart banners, and monitor metrics such as ARPDAU, fill rate, and viewability to refine performance.
Compliance, Policies, and User Trust
Follow Google Ad Policies and platform guidelines around content, disclosures, and ad placement to avoid disapproval or account suspension.
Respect user privacy, implement consent management for GDPR and CCPA, and stay aligned with evolving regulations to maintain sustainable monetization.
Best Practices and Next Steps
- Integrate the latest stable SDK version and keep dependencies updated.
- Place ads in natural flow points to preserve user engagement.
- Enable test devices during development to avoid policy flags.
- Use mediation and experiment with AdMob vs other partners for optimal yield.
- Review policy compliance regularly and act on analytics insights quickly.
FAQ
Reader questions
How does AdMob mediation affect eCPM compared to using AdMob alone?
Mediation typically increases eCPM by allowing AdMob to compete with other ad networks through waterfall or bidding setups, though results vary by audience and vertical.
Which ad formats deliver the highest fill rates on iOS and Android?
Banner and interstitial ads usually achieve the highest fill rates, with reliable coverage across regions, while rewarded video may show variable fill depending on demand.
Can Ad serving be limited to specific countries or devices for compliance?
Yes, you can block or filter ads by country, device model, or app section through ad unit settings and targeting options in the AdMob UI.
What should I monitor to avoid policy violations and sudden revenue drops?
Monitor ad placement, content policies, invalid traffic patterns, and mediation behavior, and keep SDKs and app metadata up to date to reduce risk.
