Google Ad Manager App Mediation vs Nimbus Mediation

Google Ad Manager App Mediation sends mobile app ad requests to eligible third-party networks in sequence, with yield groups defining which networks can participate. It orders eligible networks using estimated CPM and real-time Ad Exchange CPM, excluding networks expected to yield less than Ad Exchange. The mediation chain's expected yield competes with Ad Manager line items and real-time bids through Dynamic Allocation. Apps use Google Mobile Ads SDK, which calls each network adapter in turn until an ad is returned. Setup requires the SDK, adapters for selected networks, and an Ad Exchange for mobile apps account linked and set as the default for dynamic allocation. Publishers configure yield partners and groups to select networks and inventory. If none of the networks fills a request, it stays unfilled rather than returning automatically to the ad server. A serving chain can contain up to 50 networks; sequential calls in longer chains risk added latency. Google provides Android and iOS mediation guides. The listed plan is free, subject to the Ad Exchange account requirement. Third-party mediation network impressions are not eligible for Active View measurement.

Nimbus Mediation helps mobile app publishers monetize in-app inventory through programmatic auctions, direct deals and reporting. It connects publishers to more than 60 demand sources across iOS and Android apps. Nimbus describes its unified auction as zero-bias, with the highest bid winning, and supports floor controls by geography, ad type and size, including dynamic floors that respond to market conditions. The Deal Activation System runs publisher-sourced campaigns beside open-market demand without extra setup or integration. Performance Insights includes advertiser-level views, average winning bids, exchange benchmarks and direct-versus-open-market comparisons. Prebid Server demand competes server-to-server without a new SDK, while Google Partner Bidding can be activated after an SDK update. Listed demand partnerships include Amazon Publisher Services TAM, Meta Audience Network and Google AdMob Partner Bidding. Nimbus says support covers integration, optimization, floor strategies, demand tuning and bad-ad investigation. It reports encryption in transit and at rest, AICPA SOC-1 Type II certification, and GDPR, CCPA and IAB TCF readiness.
