Server-Side Tracking

Client-side vs. server-side

Traditional analytics (GA4, Adobe) rely on client-side JavaScript to capture events. The script runs in the visitor’s browser, collects data, and sends it to an external analytics server. This approach is vulnerable to ad blockers (which block the script or the outgoing request) and browser privacy features (which restrict cookie storage).

Server-side tracking moves the processing to your server. A minimal script captures behavioral signals and sends them to your own domain, where server-side logic processes, enriches, and stores the data. The server handles session management, event processing, and data forwarding — none of which can be blocked by client-side tools.

Combined with first-party collection

Server-side tracking is most effective when combined with first-party data collection. When the entire data path is first-party (your domain) and server-side (your server), the analytics infrastructure is invisible to blocking tools and immune to browser restrictions.
