Campaigns are created under an Advertiser and organize one or more Lines under shared Campaign settings. A Campaign must contain at least one Line to be eligible to deliver Impressions.

When creating a Campaign, first configure the core Campaign Setup, then apply any settings that should be shared across the Lines within the Campaign.

The general Campaign creation workflow is:

1. Navigate to the applicable Advertiser.
2. Select New Campaign.
3. Configure the Campaign Setup.
4. Configure any Campaign-level Targeting and Audiences that should apply to all Lines.
5. Configure optional Campaign-level features such as Creatives, Pixels, Pacing & Dayparts, Flights, and Frequency & Recency, when enabled.
6. Create at least one Line under the Campaign.
7. Review the Campaign and Line configuration and select Submit to save.

Important: Campaign-level settings should generally be used only when they should apply to every Line within the Campaign. Campaign and Line targeting are evaluated together, so overlapping or conflicting settings can restrict eligible inventory and limit delivery.
