Hi,
Thank you for contacting the Mobile Ads SDK support team.
The key/value approach is not formally endorsed by AdMob. There is no assurance that the custom key-values will be successfully transmitted from AdMob to GAM.
It is possible to utilize Google Ad Manager (GAM) features such as line items, audience lists, and contextual targeting. Additionally, one can contemplate employing GAM Custom Events within an application. This integration permits a direct connection of GAM with an application, effectively bypassing AdMob mediation entirely. In this manner, one can more effectively leverage GAM’s custom targeting features.
Please refer to this Targeting types document for more information.![]() |
