Measurement · Server-side GTM

Server-side tagging, implemented properly.

A senior review of your server-side Google Tag Manager setup — so the conversions you’re losing to browser restrictions, ad blockers and short cookie lifetimes come back into view, without quietly double counting the ones you already had.

  • Recover conversions that browser-side tracking is quietly missing
  • Verify that what the server sends matches what actually happened
  • Find out whether server-side earns its cost before you build it

Most server-side builds fix the transport layer and leave the data model exactly as broken as it was.

Why implementation order matters

Sound familiar?

Server-side isn’t a switch you flip. It’s a data model you have to get right.

Conversions dropped after a browser or consent change and never recovered.

You have a server container running, but nobody has verified what it actually sends.

Client-side and server-side numbers disagree and nobody can reconcile them.

Events fire twice, once from the browser and once from the server, inflating conversions.

The build was done by a developer without a measurement spec to build against.

You’re paying for server hosting without a clear account of what it recovered.

What the review covers

Six areas reviewed. One prioritized document.

Reviewed personally by a senior consultant against how your site and your business actually work — not exported from a container scanning tool.

01

Container architecture

How the server container is structured, what it receives, and whether the setup matches how your site actually works.

02

Event & data integrity

Whether events arrive once, complete, and carrying the identifiers needed to attribute them.

03

Duplication & reconciliation

Client-side and server-side compared directly, so double counting is found rather than assumed away.

04

Consent & data collection

Whether consent state travels with the data, and what that means for the numbers you report.

05

Platform destinations

What is forwarded to Google Ads, GA4 and elsewhere, and whether each destination receives what it needs.

06

Whether it’s worth it

An honest read on whether server-side earns its cost in your situation, or whether the client-side setup should be fixed first.

What changes

Numbers you can actually reconcile.

Conversions come back into view

Measurement that survives browser restrictions means bidding decisions rest on more of what really happened.

Double counting disappears

Once client and server events are reconciled, the conversion count stops flattering the account.

A spec, not a guess

Whoever builds next has a documented data model to build against rather than inherited assumptions.

How it works

Four steps. About a week. No obligation at the end.

01

Request

Two minutes on the form. We confirm fit before anything else happens.

02

Read-only access

View access to Google Ads, and ideally GA4. Never edit rights. Revoke any time.

03

Senior review

About five business days, reviewed personally — not run through an automated audit score.

04

Findings walkthrough

A 30-minute session and a prioritized document. Act on it yourself, with your agency, or with us.

Before you ask

The questions everyone asks first.

Not always, and we will say so. It earns its cost where browser restrictions are materially eroding measurement. Where the client-side setup is simply misconfigured, fixing that first is cheaper and often enough on its own.
Usually more useful. Most of what we find sits in containers that are already running, where nobody has verified what they send or whether events are being counted twice.
View access to Google Tag Manager covering both the web and server containers, plus GA4 and Google Ads so what arrives can be checked against what was sent. Hosting and DNS only come into it if you later ask us to build.
No. Nothing is published, no container version is created, and no tag is touched. If the review recommends changes, those are scoped and agreed as separate work.
A senior consultant, personally. Server-side setups fail on judgment about the data model far more often than on code, which is not work to hand to a junior.
Roughly a working week once access is in place, then half an hour walking you through what was found and in what order to deal with it.
Yes. Access is read-only, used only for this review, and revocable by you at any point without asking us. No client is ever named publicly.
