The starting point

Are your numbers really reliable?

  • Conversions are not recorded correctly

    Forms, calls, purchases or quote requests appear twice, disappear or do not match reality. Campaign decisions are then based on incomplete signals.

  • Your GTM container has become complicated

    Old tags, overly broad triggers, poorly named variables and scripts added over time make Google Tag Manager difficult to maintain and increase the risk of errors.

  • Consent and tracking are not aligned

    Your CMP, cookie banner, Google Consent Mode v2 and marketing tags need to work together. Partial setup can trigger tools at the wrong time or lose useful data.

A complete service

From assessment to deployment.

I can work on an existing setup or build a clear measurement plan from your business goals.

01

Tracking audit

Tag inventory and checks of the dataLayer, GA4 events and Google Ads conversions. Issues are explained and prioritised.

02

Corrections and cleanup

Remove duplicates, fix triggers, clarify naming and organise your Google Tag Manager container.

03

Conversion deployment

Forms, calls, useful clicks, e-commerce purchases and enhanced conversions: every event represents an action that actually matters.

04

Consent and acceptance testing

Connect your CMP to Consent Mode v2, test before and after consent, then verify with diagnostic tools.

Foundations suited to your business

The right signals, in the right tools.

The scope depends on your website and acquisition channels. The goal is to track actions that genuinely inform decisions, rather than measuring everything.

Measure less. Measure better.

POSSIBLE SCOPE

Your measurement setup

A documented, tested configuration that the people maintaining it can understand.

Google Tag Manager and dataLayerGoogle Analytics 4Google Ads and enhanced conversionsMeta Pixel and other ad platforms, as neededBusiness websites, e-commerce and forms
Clarity, right through to the documentation.

The method

A setup you can verify.

1. Define

We define useful conversions, the tools involved, the existing CMP and required access.

2. Configure

I fix or deploy tags in a controlled environment, with consistent names and rules.

3. Test and hand over

Each scenario is tested. You then receive a summary of the measurements, decisions and points to watch.

FAQ

Frequently asked questions.

Can you take over an existing GTM container?

Yes. I start with an audit to understand what works, what is no longer needed and what must be fixed. There is no need to start from scratch without reason.

Is Consent Mode v2 enough for GDPR compliance?

No. Consent Mode communicates collected consent status to Google services. It does not replace a correctly configured CMP, your legal notices or approval of your choices by your legal adviser or DPO. My work covers the technical implementation of tracking.

Do you also handle e-commerce tracking?

Yes: product views, add to basket, checkout starts, purchases, values and transaction IDs. I also check that purchases are not counted more than once.

Will I receive documentation?

Yes. Delivery includes a summary of the tracking scope, main events and checks performed. You retain an understandable foundation for future changes.
