  • ✓ Google Tag Manager
  • ✓ Looker Studio, Power BI and Tableau
  • ✓ Web analytics and KPI monitoring
  • ✓ Dashboards and reporting
  • ✓ Conversion tracking and campaign analysis

Who it's for

Small and medium businesses, local and digital service providers and brands that need measurable customer acquisition — including international (DE/EU/BR-LATAM).

The problem

Numbers from GA4, the ad account and the CRM contradict each other, conversions fire twice or not at all, and nobody trusts the reports. Decisions then run on gut feeling instead of data.

How it works

First contact → audit of current measurement → definition of relevant conversions → technical setup in GA4/GTM → verification and documentation.

My approach

I first define the few conversions with real business value, implement them cleanly in GA4 and Google Tag Manager, and verify that every event fires exactly once and only on genuine success. Data protection is considered from the start.

What's not included

No selling or operating of third-party tools, and no lock-in to a specific vendor. For complex server-side infrastructure, I bring in external specialists when needed.

FAQ

What do GA4/GTM actually measure?
GA4 collects and analyzes events (e.g. inquiries, purchases); Google Tag Manager controls when those events fire. Together they form the basis for reliable decisions.
Do I need active campaigns?
No. Tracking is useful independently of campaigns — it measures every source. But before starting paid media it is especially important.
What is reviewed in the setup?
Conversion definitions, correct firing of events, channel attribution and a traceable naming convention — plus data-protection aspects.
Does tracking guarantee more sales?
No. Tracking doesn't sell — it measures better, so that budget and optimization are steered toward the right areas.
