Questions About Tracking
Frequently Asked Questions on Tracking
Why implement server-side tracking?
Server-side tracking helps restore the reliability of your data in a digital ecosystem where traditional client-side tracking is increasingly limited. Modern browsers like Safari and Firefox, as well as ad blockers, are blocking more and more third-party cookies, external scripts, and even tools like Google Analytics. As a result, you lose valuable data, leading to skewed reports, unreliable conversion tracking, and inaccurate attribution.
By switching to server-side tracking, events (such as purchases, form submissions, or add-to-cart actions) are sent directly from your server, instead of the user’s browser. This allows you to bypass many of these client-side restrictions, while maintaining compliance with privacy laws like GDPR and ensuring proper user consent. It’s a more modern, secure and stable approach to tracking that gives you full control over your marketing data.
What are the benefits of good tracking with Analytics / Tag Manager?
Think of tracking as your marketing GPS—without it, you’re operating in the dark. With a well-configured tracking setup, you gain deep insights into user behavior, conversion paths, and the true performance of your campaigns.
You can understand why users convert (or don’t), which channels bring the best ROI, and how to optimize each step of your funnel. It’s no longer about guesswork; it’s about data-driven decisions. This allows your team to test, learn, and improve continuously.
Good tracking empowers your marketing, growth, product, and sales teams to move in sync—and make smarter decisions at every level.
Do you provide recommendations based on the collected data?
Yes, and this is one of our strongest value-adds. We don’t just deliver data—we interpret it and translate it into actionable insights. Whether it’s campaign performance, website optimization, or funnel analysis, we help you make sense of what’s working and what needs improvement.
In our ongoing collaboration (monthly reports or agile sprints), we analyze performance and provide clear, strategic recommendations—where to invest, what to test, what to optimize. We act as a true partner, not just a technical service provider.
What does the setup process for Analytics / GTM look like?
It all starts with a thorough audit of your current setup and business goals. We identify key actions and events to track, understand your conversion funnels, and map out which platforms you need to integrate (CRM, CMS, ad platforms, etc.).
Next, we deploy Google Tag Manager (GTM) on the client side, and optionally on the server side (via a server container). We integrate Google Analytics 4 (GA4) or any other relevant tools (Meta Pixel, Google Ads, LinkedIn Insight, etc.), ensuring each event is properly defined, documented, triggered, and tested. We debug and validate everything in close collaboration with your team.
The goal is to deliver a clean, reliable, and goal-driven tracking setup, so you can make informed decisions and optimize your marketing performance with confidence.
Is this setup compliant with GDPR and privacy laws?
Yes. We take data privacy and legal compliance very seriously. All tracking solutions we implement are designed to be 100% compliant with GDPR and ePrivacy regulations. This includes proper consent management using CMPs, data minimization, IP anonymization, and controlled data sharing with third parties.
In fact, when properly implemented, server-side tracking often improves compliance, as it gives you more control over what data is collected and shared, and how.
