Funky Kittens — GA4, GTM & Google Ads Conversion Tracking

A real measurement implementation for a UK e-commerce website using Google Tag Manager, Google Analytics 4 and Google Ads conversion tracking to capture meaningful customer actions and support data-led advertising decisions.

Project overview

Building a stronger measurement foundation for e-commerce advertising

The tracking setup connected the website's Google Tag Manager container with Google Analytics 4 and Google Ads so important e-commerce actions could be measured and used for reporting and campaign optimisation.

For Funky Kittens, I worked on the Google Tag Manager, GA4 and Google Ads conversion-tracking setup for the e-commerce website.

The supplied GTM workspace shows the Funky Kittens container connected to Google destinations, including a GA4 measurement ID and a Google Ads destination. It also shows tracking work on an add_to_cart GA4 tag and a Purchase – Google Ads tag.

The purpose of the implementation was to make meaningful customer actions available to analytics and advertising platforms, giving campaign analysis a stronger measurement foundation.

What the tracking setup needed

  • A central Google Tag Manager container for measurement deployment.
  • GA4 integration for website and e-commerce analytics.
  • Google Ads conversion measurement for purchase activity.
  • E-commerce event tracking such as add-to-cart actions.
  • Testing and controlled publishing of tracking changes.
My approach

How I structured the measurement implementation

The work focused on connecting the measurement platforms, configuring meaningful events and preparing conversion data for advertising analysis.

01 / Audit

Tracking Review

Reviewed the website measurement requirements and the Google platforms that needed reliable event data.

02 / GTM

Tag Management

Used Google Tag Manager as the central workspace for organising and managing tracking implementation.

03 / Events

E-commerce Measurement

Configured measurement around meaningful customer actions, including add-to-cart and purchase-related tracking.

04 / Validation

Testing & Publishing

Reviewed tracking changes before publishing so measurement could be checked and maintained more reliably.

What I implemented

The measurement components visible in the GTM workspace

The implementation brought website analytics and advertising measurement into a more organised structure using GTM as the central layer.

Key takeaways

What this conversion-tracking case study demonstrates

This implementation shows how GTM can act as the measurement layer connecting an e-commerce website with GA4 and Google Ads.

  • Google Tag Manager provides a central place to organise analytics and advertising tags.
  • GA4 event tracking helps translate customer actions into measurable website behaviour.
  • Purchase conversion tracking gives Google Ads a more meaningful signal than clicks alone.
  • E-commerce events such as add-to-cart can help explain behaviour before the final purchase.
  • Testing changes before publishing reduces the risk of deploying incorrect tracking configurations.
  • A clean measurement structure makes future troubleshooting and optimisation easier.
