What is Server-Side GTM (Server-Side Tagging)?

Running tags from the server rather than the browser. The answer to privacy, performance and the death of third-party cookies.

Detailed definition

Classic GTM runs in the browser (client-side); with iOS 14.5, the death of third-party cookies and ad blockers, data loss now reaches 30-40%. With server-side GTM the tags run on your own server (Google Cloud Run, Stape), so the data is passed to Meta and Google as first-party. The set-up is complex, but the effect on data quality is significant.

Examples

  • A beauty brand raised its Meta conversion match rate to 85% with server-side GTM (previously 55%).
