GDPR server-side tracking is the use of server-side tagging to collect and process user data in a way that is more privacy-friendly and easier to keep GDPR compliant.  In traditional browser-side tracking, user data is sent directly from the visitor’s browser to third-party tools like Google Analytics or Meta. You have little control over what data gets shared or how.

With server-side tracking, your website sends one event to a server you control. Your server receives the full event, then decides exactly what data to forward to each third-party tool. You can strip out or anonymise personal data — like IP addresses, user IDs, or device identifiers — before it ever reaches Google or Meta. 

Why it is better for GDPR:

it gives you full visibility and control over your data flows (required under GDPR’s accountability principle). It reduces the number of third-party cookies placed in the browser. It lets you apply consent rules at the server level, so data for non-consenting users is never forwarded. It also makes it easier to respond to data subject requests. 

Seers.ai offers a GDPR-focused server-side tagging solution that processes events on a secure server, applies consent rules automatically, removes personal identifiers where required, and forwards only compliant data to your marketing platforms.
