How do you traffick for Mobile devices?

 Mobile trafficking guidelines

The basic trafficking process in Campaign Manager is the same for all types of devices, including mobile: assign creatives to ads, assign ads to placements, and send tags to publishers. There is no special mobile

placement, mobile ad, or mobile tag type.

There are, however, three important areas to consider:

Placement tags: All placement tags include the additional dc_rdid= parameter, which your publisher will need to populate with resettable device IDs, and the optional tag_for_child_directed_treatment= and dc_lat= parameters. You’ll need to make sure that your publisher can populate all of these parameters correctly if your placement will serve in an app. This is necessary to enable many important features. See below for more details.

Ad and creative setup: Consider mobile targeting options if you want to limit which devices receive your ads. See below for more details.

Mobile reporting and in-app Floodlight: There are extra steps to ensure proper Floodlight tracking on in-app inventory, and to view mobile reporting dimensions. See below for more details.

App and App ID reporting:

Publishers must pass an app ID into the dc_msid= parameter to enable App and App ID reporting dimensions. For example: dc_msid=com.android.chrome for Google Play Store or dc_msid=535886823 for iOS App Store.
