About This Service

What Is Server-Side GTM Migration?

Migrating from a client-side GTM container to a server-side setup is a critical process that must be done carefully to avoid data gaps. Adslytics runs your client and server containers in parallel during migration, validates data parity, and only cuts over once accuracy is confirmed.

Why Adslytics

The Difference a Specialist Makes

Google-Certified Specialists

Every project is handled by a Google-certified tracking specialist. Not an account manager. Not a junior contractor. The person on your project is the expert.

Fixed-Price, No Surprises

You see the exact price before work starts. We scope every project fully before quoting — so you know what you are getting and what it costs, with no ongoing meter running.

Full Written Documentation

Every delivery includes documentation of what was built, what triggers each event, and how to verify it. Your team can maintain it without coming back to us.

Direct Access to Your Specialist

You communicate directly with the person doing the work. No ticketing systems, no account managers relaying messages. Direct Slack or WhatsApp contact throughout.

What Clients Say

"Our GTM container was a mess — duplicate scripts, tags firing on every page and zero documentation. The team rebuilt it from scratch with a clean data layer, proper naming conventions and a full written handover. Page speed improved immediately."

James Thornton

E-commerce Director

"We needed three different conversion actions set up across two domains in under a week before a big campaign launch. Everything was live in two days with cross-domain tracking working perfectly. No issues since."

Priya Anand

Head of Digital

"I'd tried to set up GTM myself and created more problems than I solved. Within 24 hours the team had diagnosed every broken tag, fixed the data layer and pushed a clean version. Wish I'd hired specialists from day one."

Tom Fletcher

Analytics Lead

FAQ

Frequently Asked Questions

Real answers to questions we hear from clients before starting a Server-Side GTM Migration project.

Ask Us Anything →
No — we run both containers in parallel and only switch over after validating that the server-side data matches the client-side data.
Usually 3–5 days, long enough to capture enough data to compare patterns across different traffic types.
We implement event deduplication using a unique event ID so both pathways send the same event but only one is counted.
We identify those tags upfront and keep them client-side, documenting why so there's a clear record.
Yes — we audit all custom variables and rebuild the logic using server-side variables or data transformations.
After cutover validation, we clean up or pause redundant client-side tags to avoid duplication.
We compare real-time event counts in GA4 and Google Ads between the two containers and check for discrepancies.
Yes — e-commerce migrations are our specialty. We map every purchase event, refund, and product interaction.
We document them and fix them during migration rather than carrying broken tracking server-side.
