Understanding the report

  • The aim of the report is to discover how your users index against each other. 
  • By selecting both a Test_Segment and a Base_Segment, the results given will give you an indication as to how much more likely your Top 20 Segments are to be in the Test_Segment audience rather than the Base_Segment audience.
  • On the right hand side you can see the total number of Uniques in your Base and Test Segments over the Date Range selected in the filter.
  • If you hover over the different indexes, you can see the number of uniques each segment has. Note: If a segment has a low number of uniques it may Index higher with the Test_Segment. Make sure to set a value in the 'Minimum Uniques' filter to ensure viable figures are being returned.


I am looking to go out and sell an 'Interest in SUV' audience and I want to understand how they index against my 'Auto Intenders' segment.

From my results I can see that

  • Across the 'Interested in SUV' segment over the past week, users are 1.37x more likely to be in the 'Investment Audience' segment, 1.22x more likely to be in the '45-54' demographic and 1.21x more likely to own a cat than general 'Auto Intenders'.

Troubleshooting - If an error or abnormal results appear:

  • Make sure you have set a Base Segment and a Test Segment
