When you run an AB test or personalize a page, the resulting metrics will tell you which variant won, but they rarely tell you why. To truly understand how visitors are experiencing your dynamic content, filtering recordings by experiment variant shows you not only which variant won, but how visitors actually behaved on each one.
That is why we are thrilled to announce our new integration with Microsoft Clarity.
Once set up, this integration tags every Clarity session with the experiences they see, the audiences they fit into, and the experiments they participate in. This allows you to watch recordings and view heatmaps specifically segmented by those precise variables.
Test individual elements or full journeys with advanced AI-powered segmentation, great performance, no-code rollouts, and flicker-free experiments.

How the integration bridges the gap
The integration reads the visitor's session data from Croct and sets it as custom tags on Clarity.
Because a session's audiences, experiences, and experiments can change throughout the session, the tags are refreshed on every pageview, even for single-page applications. Once active, the integration sets the following custom tags on the Clarity session:
- croct_experiences: The name of the experiences that impacted the session.
- croct_audiences: The name of the audiences from the experiences the user fits.
- croct_experiments: The name of each running experiment and the variant assigned to the session.
What you can uncover
Once the custom tags are flowing into Microsoft Clarity, you unlock a completely new layer of qualitative analysis:
- Filter session recordings: Instantly filter your session recordings by audience, experience, or experiment variant.
- Compare heatmaps: Compare heatmaps between the variants of an experiment to visually analyze how structural changes impact scrolling and attention.
- Identify friction points: Spot where visitors drop off, rage click, or hesitate on the page.
Start seeing exactly how your experiments perform in the real world. Set up the Clarity integration today and turn what you observe into your next winning experience.
