Normally (client-side tracking):
When someone visits your website, their browser sends data directly to platforms like Google Analytics or Facebook Ads.
Example: “Adriaan clicked this button!” gets sent straight from the visitor’s device to Google.
With server-side tracking:
Instead of sending that data straight to Google, the browser sends it to your own server first (like a middleman you control).
Then your server takes over:
Your server receives the data, cleans it up if needed, maybe adds extra info (like CRM data), and then sends it to Google, Facebook, etc.
The big advantage of server-side tracking is that it’s much harder to block than traditional client-side tracking (which runs in the browser and can be blocked by ad blockers, ITP, etc.).
