Google Ad Manager App Mediation

Google Ad Manager App Mediation manages mobile app ad requests by calling eligible third-party ad networks in sequence. Yield groups determine which networks can respond to each request, and Ad Manager orders those networks using estimated CPM and real-time Ad Exchange CPM. The chain’s expected yield competes with Ad Manager line items and real-time bids through Dynamic Allocation. An app sends requests through Google Mobile Ads SDK, which calls network adapters in order until an ad is returned. Setup requires the SDK, adapters for each selected network, and an Ad Exchange for mobile apps account linked and set as the default for dynamic allocation. Publishers configure yield partners and yield groups to choose networks and available inventory. If none of the networks fills a request, it stays unfilled rather than automatically returning to the ad server. A serving chain can include up to 50 networks; sequential calls in longer chains risk greater latency. Android and iOS setup guides are available. Ad inspector can check fill, show errors, display mediation details, and test a yield partner on a device. The plan is free, subject to the account requirement.

App Mediation provides a sequential way to involve third-party networks in mobile ad serving and Dynamic Allocation. Setup requirements and the unfilled-request behavior are important considerations.

This is for app developers and publishers who want third-party ad networks to compete for mobile app ad requests. It suits teams able to configure the required SDK, adapters, and Ad Exchange account.

Overview

Google Ad Manager App Mediation routes mobile ad requests through eligible third-party networks in yield order, while letting that demand compete with other Ad Manager demand. It is best suited to app publishers already using Google’s ad tools and able to meet the account and SDK prerequisites. Its appeal is coordinated yield competition; its main drawback is a sequential process that can add latency and leave a request unfilled.

Key features

Publishers use yield groups to choose which networks can serve particular inventory. Ad Manager ranks eligible networks using estimated CPM and real-time Ad Exchange CPM, excluding networks expected to yield less than Ad Exchange. Automatic data collection can estimate a network’s CPM from historical CPM data adjusted for impression discrepancies, helping publishers avoid supplying that estimate manually.

The mediation chain’s expected yield competes through Dynamic Allocation with Ad Manager line items and real-time bids from Authorized Buyers and Exchange Bidders. That makes this a stronger fit for publishers who want third-party mediation considered alongside their other Ad Manager demand than for those seeking a standalone mediation auction.

Requests pass through the Google Mobile Ads SDK, which calls network adapters sequentially until one returns an ad. A serving chain can include up to 50 networks, but more callouts can mean more latency. If no network fills the request, it remains unfilled; Ad Manager does not automatically send it back to the ad server.

Publishers create yield partners and yield groups to configure networks and inventory. Ad inspector can check fill, show errors, reveal mediation details for a request, and test an individual yield partner on a device. Participating networks can serve rewarded and rewarded interstitial formats when selected in a yield group. The SDK can pass a child-directed age treatment signal to third-party networks, though developers remain responsible for those networks’ ad treatment. Third-party mediation network impressions are not eligible for Active View measurement.

Pricing

The Google Ad Manager App Mediation plan costs free. It includes up to 50 mediation networks in a serving chain. The free price is attractive for publishers evaluating mediation, but it does not remove the setup requirements: an Ad Exchange for mobile apps account must be linked and set as the default for dynamic allocation. An AdSense account is also required to work with Google Ad Manager.

Platforms

The mediation setup guides cover Android and iOS apps, and the software is listed for Android, iOS, and web. Mobile apps must use the Google Mobile Ads SDK and implement adapters for each third-party network they mediate. A yield partner absent from the available network options can be added as an Other company, but that route requires custom events in the app as well as yield groups.

Who it's for

This is a practical choice for app developers who already use Ad Manager and can link an Ad Exchange for mobile apps account, and who want third-party network demand considered alongside line items and real-time bids. It is less suitable for teams that cannot take on SDK and adapter integration, need an automatic fallback when every network fails to fill, or rely on Active View measurement for third-party mediation impressions. Publishers configuring yield partners should also account for applicable privacy rules, including CPRA, GDPR, and LGPD.

Pros and cons

• Pro: Yield groups and CPM-based ordering help direct requests to eligible networks with stronger expected yield.
• Pro: Mediation competes through Dynamic Allocation with Ad Manager line items and real-time buyer bids, rather than operating apart from that demand.
• Pro: Ad inspector can diagnose fill and errors, inspect request-level mediation details, and test a yield partner on-device.
• Con: Sequential network calls can increase latency, with a 50-network serving-chain ceiling.
• Con: A request stays unfilled when no network responds with an ad; there is no automatic return to the ad server.
• Con: Setup depends on Google Mobile Ads SDK, network adapters, and a linked Ad Exchange for mobile apps account set as the dynamic-allocation default.
• Con: Third-party mediation impressions cannot be measured with Active View.

Verdict

Choose Google Ad Manager App Mediation if your app already fits into Google’s ad stack and you want third-party network yield to compete alongside Ad Manager demand. Yield-based ordering and Dynamic Allocation are its clearest advantages. Look elsewhere if the required account and integration work, sequential latency, or lack of automatic ad-server fallback does not suit your operation.
