Google Tag Manager, implemented properly
Most tracking problems don't announce themselves. They show up later as numbers that don't reconcile, conversions your ad platforms never learn about, and reports nobody quite trusts. We set up Google Tag Manager so the data behind your decisions is actually right, from the data layer up to server-side tagging.
Talk to our team
The control room for your marketing data
Picture every tag on your website, Google Analytics, the Meta pixel, Google Ads conversions, a chat widget, a heatmap tool, as a separate wire running into your site. Add them the old way, hard-coded one at a time, and you end up with a tangle nobody wants to touch. Edit the wrong line and a purchase quietly stops being recorded. Wait on a developer for every small change and your marketing team stalls.
Google Tag Manager replaces that tangle with a single container you manage from one place. Tags fire on rules you define, a page view here, a completed checkout there, without touching site code every time. That much most people already know.
What separates a setup that works from one that leaks data is everything underneath: a clean data layer, triggers that fire once and at the right moment, variables that pull the correct values, and a container that doesn't slowly become the mess it replaced. Underneath is where we spend our time.

What we do with Google Tag Manager
From a first clean install to a full server-side setup feeding your ad platforms, here is the work we take on.
Setup & Migration
A fresh, structured GTM install, or a rescue of a container that has grown messy over the years. We move hard-coded tags into GTM, clear out duplicates, and leave you with a naming convention your team can actually follow.
Data Layer & Ecommerce Tracking
The data layer is the difference between guessing and knowing. We build one that reports products, prices, and checkout steps accurately, then wire up GA4 ecommerce events such as view_item, add_to_cart, begin_checkout, and purchase.
Server-Side Tagging
Move tracking off the browser and onto a server you control. That means fewer blocked tags, longer-lived first-party data, and cleaner signals for your ad platforms. We host, configure, and maintain the whole environment.
Conversion Tracking & CAPI
Accurate conversions feeding Google Ads, Meta, TikTok, and Snapchat, with Enhanced Conversions and the Conversions API set up correctly and event IDs matched between browser and server so nothing gets counted twice.
Consent Mode & Privacy
Consent Mode v2 wired into your consent banner so tags respect a visitor's choice before they fire. You stay on the right side of GDPR and similar rules, and still recover modelled conversions where it is permitted.
QA, Governance & Debugging
The unglamorous work that keeps data honest: version control, Preview-mode testing, and finding the tag that broke after your last theme update, before it costs you a month of reporting.
The one upgrade that fixes the most problems at once
Ad blockers, browser tracking limits, and short cookie lifetimes chip away at browser-based tracking every year. A meaningful slice of your visitors never load your tags at all, which means real purchases and leads your reporting simply never sees.
-
Recover lost conversions: server-side events are far harder to block than page-side tags, so you capture sales the browser misses.
-
Feed better data to ad platforms: cleaner, more complete signals help Google and Meta optimise, which usually shows up as lower acquisition costs.
-
Keep control of your data: everything passes through infrastructure you own, so you decide what each vendor receives and how it is hashed.
How a GTM project runs with us
1. Audit & measurement plan
We start by mapping what you need to measure and checking what your current setup really reports, not what it claims to.
2. Build the data layer & tags
We implement the data layer, triggers, and tags, browser-side or server-side, following a plan rather than bolting things on.
3. Test against real transactions
Every event is validated in Preview mode and reconciled against actual orders, so the numbers hold up before anything goes live.
4. Document & hand over
You get clear documentation of the container and the option of ongoing support, so nobody is left guessing six months from now.
Tracking is easy to switch on and easy to get wrong
Anyone can paste a container snippet into a theme. The gap between that and a setup you can build a marketing budget on is where we live. We have spent years fixing tracking on live ecommerce stores, often under the pressure of a busy sales period, so we know where it tends to break.
-
Analytics and engineering in one team. We write the code and understand the marketing, so nothing gets lost in translation between a developer and a data specialist.
-
Server-side is our default, not an add-on. We have built these setups across Shopify, WooCommerce, and custom platforms.
-
We answer to your numbers. A tag that fires is not the goal. Data that matches reality, and holds up when you check it, is.
Questions clients ask us
Straight answers to the things people usually want to know before they start.
Isn't Google Tag Manager something I can set up myself?
You can, and for a simple site that is a reasonable start. The trouble usually appears later: an ecommerce data layer that reports the wrong revenue, conversions counted twice, or tags that keep firing after a page has changed. Most of our GTM work is fixing setups that looked fine on day one.
Will all these tags slow down my website?
Done carelessly, tags do add weight. Done well, GTM actually helps, because tags load asynchronously and you remove the ones you no longer use. When we move tracking server-side, even more of that work leaves the visitor's browser, which tends to help page speed rather than hurt it.
What exactly is server-side tagging, and do I need it?
Instead of a dozen vendor scripts firing from the browser, your site sends events to a server you control, which forwards clean data to each platform. If you spend on paid ads or depend on accurate ecommerce data, it is usually worth it. If you run a small brochure site, it may be more than you need. We will tell you honestly which camp you are in.
Does this work with Shopify and WooCommerce?
Yes. We work with both regularly, along with custom platforms, and we know the quirks of each, from Shopify's checkout limitations to WooCommerce hooks. The approach adapts to your stack rather than forcing your stack to change.
Is a GTM setup compliant with GDPR and consent rules?
It is when consent is built in from the start. We wire Consent Mode v2 into your consent banner so tags wait for a visitor's choice, and we keep data handling transparent. Compliance is part of the build, not a checkbox added at the end.
How long does a typical project take?
A clean GA4 and GTM implementation is usually a matter of days once we have access. A full server-side build with conversion APIs and consent handling takes longer, and we will give you a realistic timeline after the initial audit rather than a number designed to sound good.
