DoubleClick Ad Exchange

You can exclude audiences by adding remarketing lists and custom combination lists to the Negative audiences section.

1. Click the Campaigns main tab.
2. Click the Display Network tab.
3. Click the Remarketing tab.
4. Expand theExclusions link under the Audience table.
5. Click the Remarketing tab to display the current list of audience lists at both the ad group level and the campaign level.
6. Select the audiences to exclude, then click Add exclusions.

Targeting a remarketing list or custom combination while excluding audiences results in a subtraction of users against the targeted list(s). Targeting a negative audience uses an AND relationship, which allows for the subtraction.
