The Matomo Cohorts report lets you analyse how visitors assigned to a specific A/B test variation behave over time. By filtering the report by a segment based on the experiment variation, you can compare visitor retention and engagement to better understand the longer-term impact of your A/B test.

  1. Create a Segment based on the A/B test variation name.
  2. Open Visitors > Cohorts and apply the Segment to the Cohorts report.

This will give you a clear picture of the performance of the variation matching the condition of Segment. To ensure accurate reports, each A/B test variation name must be unique.

Note: The Cohorts premium feature is included in Matomo Cloud. Matomo On-Premise users need to install and activate both plugins (Cohorts and A/B Testing) before using this feature.
