GTM Server-Side Tracking
Server-side tracking that survives ad blockers and cookie restrictions — accurate data, always.
Browser-side tracking is increasingly unreliable: ad blockers, ITP, iOS restrictions, and cookie consent tools all reduce your data accuracy. Server-side GTM moves event collection to your server, where none of these restrictions apply. We set up a full server-side GTM container with GA4, Meta CAPI, and any other platform you need — so your analytics and ad platforms receive clean, complete data regardless of what happens in the user's browser.
The Problem We Solve
A huge share of events never gets tracked because ad blockers and iOS restrictions block them.
Ad platforms are optimizing using only browser-side data — missing a large piece of the real picture.
Stacking too many client-side tracking scripts slows the site down for real visitors.
What's Included
Google Tag Manager server-side container deployed on GCP, AWS, or Stape.io — fully managed and monitored.
GA4 events routed server-side for accurate session data without ITP or ad blocker interference.
Facebook Conversions API events sent through sGTM — deduplication, event matching, and custom data included.
First-party cookie implementation for 7-day to 400-day user recognition — replacing third-party cookies.
TikTok Events API, Pinterest API, Klaviyo, and other platforms can be added to the server container.
Full event verification across all connected platforms, plus ongoing monitoring alerts for data gaps.
“We knew we were losing some tracking data to ad blockers, but we didn't realize how much until Groweik set up server-side GTM. Our reported conversions jumped almost 40% just from capturing events we'd been blind to.”
