Server-Side Tagging & Google Tag Gateway - first-party, always.

Ad blockers, browser restrictions, and third-party cookie deprecation are eroding your analytics data every day. Server-side GTM combined with Google Tag Gateway moves your data collection to your own first-party infrastructure - accurate, resilient, and built for the privacy-first web.

What We Do

The complete server-side stack.

Server-side GTM moves tag execution from the visitor's browser to a server you control. Combined with Google Tag Gateway - which serves GTM scripts through your own domain via reverse proxy - the entire data flow becomes first-party and invisible to ad blockers. We implement both layers together, including client configuration, custom clients, server-side tag routing, and first-party cookie management.

Our Process

How we approach every engagement.

Discovery & Audit

We start by understanding your business goals and reviewing your current setup - identifying gaps, issues, and opportunities before writing a single line of configuration.

Plan & Document

We produce a detailed measurement plan and tracking specification before implementation begins - so your development team has everything they need and there are no surprises.

Build & Validate

Implementation is done in staging first, validated with ObservePoint, Tag Inspector, and Chrome DevTools, then moved to production only when everything checks out cleanly.
