Custom Audiences

In Ad Manager, it is possible to add custom segments to an advertiser’s environment. This process works via a so‑called “share key”. This key is created by the DPG Data Team at the advertiser’s request and then shared with the DPG Platform Success Team.

Available Segments via Custom Setup

The following segments can be shared through the custom setup:

• Multichannel: Segments used across channels (for example, from video to display).
• Retargeting: Retargeting impressions or clicks from a specific campaign.
• Custom Segments: Manual or complex segments that cannot be created through the standard UI or Datalab.
• A/B/C Testing: Specific segments used for experiments.
• Data Cleanroom: Segments originating from secure data environments (such as InfoSum or LiveRamp).

Request Process & Support

Requests for new segments or support follow the standard procedue. Create a ticket: submit a request via Freshdesk. This ticket will be handled by the Platform Success Team, and contact will be made via email.

Usage

Within ad groups, available segments can be selected in the “external audiences” section to either include or exclude them.

Lifecycle & Expiration

The following guidelines apply to the management of segments:

• Standard Retention: A segment has a default period of 90 days unless specified otherwise in advance.
• Responsibility: The advertiser is responsible for monitoring active segments.
• Safety Net: There is a retention period for expired segments.
• Expired Segments in an active campaign: If a segment has expired, but is still active within a campaign, it will not be removed.
