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

Use Case

With the Ad Unit Overlap report, you can gain insight into where your audience overlaps across your web properties. The report considers your 100 top related properties and shows you the overlap between them.

Using the Ad Unit Overlap Report

Use the Top N Base Ad Units and Top N Overlapping Ad Units controls to select your desired number of ad units 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 Base Ad Unit and the Overlap Ad Unit controls to select which of your ad units you want to display in the overlap report.

IMPORTANT

When enabling Audience Optimization for Publishers, you must include descriptive metadata for Ad Unit IDs, as described in Step 3 of Import Google Ad Manager (formerly 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.
