Server-Side Tracking & GA4 Consulting: Because Your Data Is Probably Lying to You
The foundation of every successful digital strategy is data you can trust. I help you cut through the noise and build an analytics setup that gives you an honest picture of what’s actually happening.
The data problem most businesses don’t know they have
Knowing who visits your website, what they do there and why they buy – or don’t – is the bedrock of smart marketing. But the reality nowadays is that most standard analytics dashboards are significantly inaccurate. Ad blockers, Safari’s Intelligent Tracking Prevention (ITP), broken consent banners and the gradual death of third-party cookies are silently eating your data. You might be missing 20–40% of your conversions without realising it.
I advise and support you as a Digital Growth Consultant in building an analytics strategy that fits your business – one you can actually rely on. I take care of the technical setup end-to-end, so you don’t have to become an expert yourself. The result: a clean dashboard, accurate conversion data, and the confidence to make decisions based on facts rather than estimates.
Through the precise implementation of Server-Side Google Tag Manager (sGTM) alongside tools like Google Analytics 4 or Matomo, we make your data infrastructure resilient against signal loss – while keeping sensitive data off third-party servers until it’s been properly handled. On request, with EU-based hosting for full data sovereignty and GDPR compliance.
