Ad Types and Specification

A Placement is a location within your app where ads can be displayed. This may be when you open the app, between levels of a game, or within your app's feed. An ad unit is the type of ad that is served in that location.

Each placement accommodates one ad type. You must integrate at least one placement to begin showing ads from DT Exchange buyers.

If the device is set to mute, the ad plays with sound off. If the device is not set to mute, the ad plays with sound on.
