User ID Data Layer
Data layer push examples for tracking the user id.
Most websites and apps create a unique user ID to identify individual users. Including the user id in tags for GA4 and other platforms can greatly improve data quality. Each event data layer push can be used to test tracking tags by firing it in the browser console. These example data layer pushes can be used in a website or app tracking implementation by replacing the example values with dynamic or hard-coded values relevant to the specific application.
| Event | Description |
|---|---|
| user_id | Push this event on every page to reflect the unique user id associated with the user. |
