App Monetization
Google AdMob
Google AdMob is Google's mobile app advertising and monetization platform for Android and iOS developers. It provides Google demand, banner, interstitial, native, rewarded, app-open, and video formats, plus mediation, real-time bidding, reporting, brand-safety controls, and integrations with services such as Firebase. It suits developers of many app categories that want an accessible first monetization stack or a mediation layer, provided ad placement, consent, policy compliance, retention, in-app purchases, and user experience are optimized together.
What it does
Google AdMob is the most widely adopted entry point for mobile app monetization. Developers integrate the Google Mobile Ads SDK and serve banner, interstitial, rewarded, rewarded interstitial, native, and app open formats filled by Google's advertiser demand. Its bidding-based mediation lets dozens of third-party networks compete in real time alongside Google demand within one SDK. Controls cover ad content ratings, category and advertiser blocking, and frequency; reporting spans impressions, eCPM, and revenue by format and country, with deeper user metrics through the Firebase integration. Consent management tooling addresses GDPR and other regimes. It is free to use, with Google taking its margin inside the auction.
Where it fits
AdMob is the entry tier of app monetization, often later compared against or combined with LevelPlay and MAX as publishers grow into mediation operations.

Beginner notes
- Respect placement policy strictly, because accidental clicks from ads near buttons are a common cause of account suspension.
- Rewarded ads usually earn more and annoy less than interstitials, so design reward placements into the product rather than bolting banners everywhere.
- Watch retention alongside eCPM; aggressive ad frequency raises short-term revenue while quietly killing the user base that generates it.
