About AdMob

Google AdMob is Google's mobile app monetization platform for developers and publishers that want to earn advertising revenue from Android and iOS apps. It combines Google advertising demand with mediation for third-party ad networks, bidding, multiple mobile ad formats and app-level reporting. This page focuses on AdMob itself; Google's wider advertising portfolio is covered on the Google Ads brand page.

What does Google AdMob do?

AdMob helps app developers serve ads inside mobile applications and manage the resulting monetization workflow. Developers integrate the Google Mobile Ads SDK, create ad units and choose formats such as rewarded, native, banner and interstitial ads. Google then supplies advertising demand through its network, while AdMob can also coordinate eligible third-party demand sources.

The product is designed around mobile app inventory rather than general website advertising. That makes it different from AdSense, which is primarily used for websites, and from Google Ad Manager, which is aimed at publishers that need broader inventory types, direct sales and more advanced ad-serving controls.

How do AdMob mediation and bidding work?

AdMob Mediation lets developers manage multiple ad sources in one place. Google currently supports two main mediation methods: bidding and waterfall. Bidding lets participating ad sources compete in a real-time auction for each eligible impression. Waterfall mediation calls configured sources in sequence using expected eCPM values. AdMob can combine both approaches in a hybrid mediation group.

This structure can increase competition for inventory, but it also adds operational work. Developers still need to configure supported networks, maintain SDK adapters where required, monitor fill rates and revenue, and make sure mediation settings match app regions and ad formats. Partner bidding also allows Google demand to participate in supported third-party mediation platforms without using AdMob as the primary mediation layer.

Which ad formats does AdMob support?

AdMob supports several common mobile advertising formats. Rewarded ads let users choose to watch or interact with an ad in exchange for an in-app reward. Native ads can be styled to fit an application's layout. Banner ads occupy a persistent area of the screen, while interstitial ads appear at natural transition points. App open ads and rewarded interstitial formats are also available for supported use cases.

Format selection should be driven by user experience as much as revenue. An ad format that produces a higher short-term eCPM can still be a poor choice if it interrupts core actions, increases churn or encourages accidental clicks. Developers should test placements carefully and follow Google's implementation and policy guidance.

How does AdMob connect with Firebase and analytics?

AdMob can integrate with Google Analytics for Firebase so developers can combine advertising data with app engagement and user behavior. This can help teams examine lifetime value, audience behavior and monetization results instead of evaluating ad revenue in isolation. AdMob also supports impression-level ad revenue data, which can be sent into internal systems or other analytics tools for more detailed lifetime-value calculations.

Measurement quality depends on implementation. Teams should validate event collection, app identifiers, consent handling and revenue data before making product or acquisition decisions from the reports.

How much does Google AdMob cost?

Pricing checked on August 23, 2026. AdMob is not sold as a normal monthly software subscription, so there is no universal seat price to publish. Developers earn revenue from ads served through the platform, while the economics depend on advertiser bids, ad format, geography, user behavior, demand source, mediation configuration and applicable platform fees.

Google's current transparency documentation exposes auction gross revenue, seller platform fees and publisher payout information for certain regulated traffic where required. That is more accurate than claiming AdMob is simply free or assigning one fixed commission percentage to every impression. Payment thresholds also vary by reporting currency. For USD accounts, Google's current payment threshold is $100, with a $10 verification threshold.

What should developers know about app readiness and policy compliance?

New apps added to AdMob must go through an app readiness process before they can fully serve ads. Developers also need to comply with Google publisher policies, invalid-traffic rules, consent requirements and applicable platform or regional regulations.

Account health matters because estimated earnings can be adjusted when Google identifies invalid activity or policy issues. Teams should avoid designing interfaces that encourage accidental ad clicks, review traffic anomalies and keep SDK implementations current. Privacy and consent requirements should be handled as part of the app architecture rather than added only after monetization has launched.

What are AdMob's main limitations?

AdMob can simplify access to Google demand and third-party mediation, but it does not guarantee a particular revenue level. Earnings depend on the audience, inventory, advertiser demand, app category, geography and implementation. Mediation also increases dependency on multiple SDKs and network relationships, which can affect app size, release testing and operational complexity.

Developers that require highly customized direct-sales workflows, web and connected-TV inventory, or advanced programmatic controls may find Google Ad Manager more appropriate. Teams that want a different mediation strategy may compare AdMob with AppLovin MAX, Unity LevelPlay or other mobile monetization platforms.

Who should choose something else instead of AdMob?

A developer whose app has very low engagement or a small audience may get more value from subscriptions, paid downloads or in-app purchases than from adding advertising early. Apps with sensitive user experiences may also decide that advertising creates more friction than value.

Larger publishers with direct advertiser relationships and several inventory types should evaluate Google Ad Manager. Developers already committed to another mediation platform may prefer to keep that platform and use Google's partner bidding support for Google demand where available. AdMob is strongest when mobile app advertising is a meaningful revenue stream and the team wants Google demand plus a centralized mediation workflow.
