What Chartboost Mediation is
Chartboost Mediation is a free monetization solution for mobile app developers on Android and iOS. It uses bidding to increase competition for ad impressions, with a unified auction that runs real-time bidding across demand sources and shows why a particular bid won. Chartboost says it offers access to 50+ top-demand sources. Developers can use bidding or waterfall setups, although some partners do not support both.
The analytics dashboard filters performance by app, placement, ad type, network source, country, and date range, and supports custom reports. One-click A/B testing can compare bidding, non-bidding, and other monetization setups. Chartboost bidding supports banner, rewarded video, and interstitial formats. Listed mediation partners include AdMob/Google, Amazon Publisher Services, AppLovin, BidMachine, InMobi, Liftoff Monetize, Meta Audience Network, Mintegral, MobileFuse, and Unity Ads (Levelplay). Chartboost says its bidding partners have no demand fees and the winning bid equals publisher earnings. Setup involves importing apps, selecting networks, configuring placements and ad groups, and integrating the Mediation SDK. SDK integrations are listed for Android and iOS at version 5.4.0 and Unity at version 5.3.0.
