For publishers using app platform feature(s), publishers are not
permitted to pass the impression opportunity through any intermediary
(including publisher’s own system) that dynamically or programmatically
allocates ad requests based on actual, estimated, or other real-time
pricing information. App platform feature(s) include Open Bidding.
Due to technical reasons, I'm currently unable to use the AdMob Mediation Service. Is it allowed to install both AdMob SDK and an alternative Ad Network SDK (not Adapter). Then first load a Banner from the alternative Ad Network SDK and only if it doesn't return a Banner, request one from AdMob (as backup)? Everything is managed in the app, no server.
Best regard,
