A guide to navigating Index and Overlap insights for Campaigns
Note: Campaign insights are only available for PG deals that do not contain any video creative or third-party hosted creative
This data can be useful in post-campaign analysis once a campaign has wrapped up, or mid-campaign for campaign optimization.
At the top of the Index and Overlap insights dashboard, you will see Campaign and Filter. If you click 'Edit' next to Campaign you can choose which Ad Manager campaign or campaigns for which you want to see index and overlap data.
If you click 'Edit' next to Filter, you will see the filters available to apply to the data.

To specify which cohorts you want to measure your selected campaign against you will need to select a base cohort as well as comparison cohorts.
- Base Cohort - The base cohort is the base line or 'average user' that you want to index your campaign-targeted users against. You can only select one base cohort.
Note: Base Cohort only pertains to index and has no effect on overlap
Tip: Set the base cohort to 'Everyone' to see how much more likely users are to belong to a comparison cohort than all other users on your site.
- Comparison Cohorts - Comparison cohorts will be the cohorts or tag groups that populate the list. Choose the cohorts for which you want to see the overlap and index of the users who interacted with the campaign or group of campaigns you selected. You can also click 'Select All Cohorts' to see how users targeted by your campaign compares to all cohorts you have created.
- Minimum Uniques - If you set minimum uniques, the chart will only return comparison cohorts that meet that minimum. If a comparison cohort you selected do not meet the minimum, it will not appear in the chart regardless of the fact that it is selected.
Interpreting the Data
Once you have selected your campaign (GAM order ID), base cohorts and comparison cohorts you are ready to analyze the data.
In the example above, we are seeing how users who viewed Campaign 211706487 overlap with cohorts we have created, as well as how users who viewed the campaign index against them.
- Overlap - Looking at Sport Enthusiasts, we see a 52.51% overlap. This means that 52.51% of users who viewed campaign 211706487 fall into our Sports Enthusiast cohort.
- Index - The index goes off a base of 100 and indicates that users who viewed campaign 211706487 are 56% or 1.56x more likely to be in the Sport Enthusiast cohort than average users are.
