Segment to Ad Unit Overlap

The Segment to Ad Unit Overlap report is displayed as a heat chart that highlights high and low overlaps between your Ad Units and Audience Manager segments.

Use Case

With the Segment to Ad Unit Overlap report, you can understand which audiences visit your web properties. The report displays the overlap between members of your Audience Manager segments and the number of visitors to your web properties. A higher overlap means that many members of a segment visit your web property.

Using the Segment to Ad Unit Overlap Report

Use the Top N Ad Units and Top N Segments controls to select your desired number of ad units and segments for the overlap. You can select a maximum number of 100 items for each.
Use the Day Range and Date Through controls to adjust your look-back range. Note that the 7-day and 30-day look-back periods are only available for Sunday dates.
Use the Segment Name and the Ad Unit boxes to filter any of segments and ad units.
When enabling Audience Optimization for Publishers, you must include descriptive metadata for Ad Unit IDs, as described in Step 3 of Import DFP Data Files Into Audience Manager . By doing this, you assure that the report details the web property as Ad Unit instead of the Ad Unit ID.
