# TRACKING event

The TRACKING event is automatically generated every time an experience or experiment runs for the guest. The TRACKING event is available in the guest profile and can be used in segmentation, decisioning, exclusion, and analytics.

Example 59. TRACKING event object

Here's a TRACKING event generated after the experience with the `friendlyId` of running_shoes_popup_02 ran for the guest.

For example, the event data can be used in the following ways:

- Create a segment of guests who viewed this pop-up but haven't made a purchase.
- Use the segment in decisioning to target guests with a follow-up email campaign.
- Analyze the `flowExecution` data to track how many guests saw the experience and how many conversions occurred.
