The GMA SDK offers some advanced features that allow publishers with unique requirements to serve ads in their mobile apps.
Support for child-directed apps
Publishers can mark their ad requests to be treated as child-directed to facilitate compliance with COPPA.
Send messages to the app
GMA SDK has app events that allow Google Ad Manager creatives to send messages to the app and take action accordingly. This allows for a wide variety of possibilities including dynamically changing creative behavior and changing the look and feel of the creative.
Additional backfill options
If you’re using Ad Exchange backfill, there are parameters such as Content URL that can be passed via Google Ad Manager.
