- 1.
JavaScript SDK docs – The section on tracking UTM tags explains that UTM parameters are persisted as super properties by default, and how to disable this behavior using stop_utm_persistence: true. [Track UTM Tags]
- 2.
Traffic Attribution best practices – The web attribution section covers how UTM parameters are tracked and persisted, including the recommendation to disable persistence for compatibility with attribution models. [Web Attribution]
- 3.

To disable UTM persistence, you can initialize the SDK like this:
mixpanel.init('YOUR_PROJECT_TOKEN', {
stop_utm_persistence: true
});Mixpanel recommends disabling UTM persistence (stop_utm_persistence: true) for the best compatibility with their Attribution feature.
