What is server-side tracking?

Measurement that goes through your own server instead of the visitor's browser. More stable data in a cookieless world, and more control over what is shared.

The browser sends an event to your own server, which in turn forwards what you have chosen to the respective tool. You decide what leaves the house and what stays.

The benefit is more stable measurement when browsers block scripts and shorten cookie lifetimes. Consent is still needed: the rules apply just as much when the measurement moves to the server.
