Tracking & Measurement

Reliable measurement is the foundation of every smart marketing decision

Everyone talks about data-driven marketing. Almost nobody talks about whether the data is actually reliable. The measurement layer determines the quality of every optimization decision downstream.

Scope

What's included — and what isn't.

Clarity on what this service actually solves, so there's no mismatch in expectations.

Included

  • GA4 custom event implementation and configuration
  • Server-side tagging and consent architecture
  • Conversion definitions aligned to the business
  • Data quality audit and validation
  • Tracking architecture documentation

Not included

  • Paid campaign management (that's PPC/Google Ads)
  • Product or website feature development
  • BI tools or dashboards outside the Google ecosystem
  • GDPR legal advice — I handle the technical architecture, not legal counsel
  • Historical Universal Analytics data migration

Decision-oriented measurement

GA4 should start with questions, not available events.

More events do not mean better measurement. The goal is architecture explaining behaviour, conversion and quality without ignoring consent or limitations.

Layers I validate

Measurement plan

Goals, questions, KPIs, events, parameters, identities and owners behind each decision.

Collection and consent

Google tag, GTM, Consent Mode, CMP, cross-domain, referrals, data layer and behaviour before and after choice.

Quality and use

Debugging, duplication, naming, filters, attribution, retention, integrations and dashboards used by real people.

Possible deliverables

  • Measurement plan
  • Event and data-layer specification
  • Configuration and QA
  • Consent map
  • Dashboard and usage guide

What data cannot guarantee

  • GA4 is not a perfect source of truth
  • Modelling is estimation, not observation
  • Consent Mode replaces neither a CMP nor legal advice
  • Attribution depends on definitions and integrations

Frequently asked questions

Do I still need to migrate from Universal Analytics?

Universal Analytics is already off. If GA4 isn't properly set up with key events, it's urgent — without it there's no reliable data for decisions or Google Ads bidding.

When does server-side tracking make sense?

When signal loss (iOS, ad-blockers, consent) starts distorting decisions, when events need to be enriched with CRM data, or when compliance (GDPR) requires full control over what leaves the server.

Do you work with Consent Mode v2?

Yes. I implement Consent Mode v2 with certified CMPs to keep Google Ads and GA4 conversion modeling working while respecting GDPR.
