Analytics & Tracking
Google Analytics, Tag Manager, Conversion Tracking: We set up your analytics system to ensure it delivers reliable data while respecting data privacy.
Analytics and Tracking Agency
Many websites collect data, but few actually use it. We’ll set up your analytics and tracking so that the right data is collected, neatly structured, and presented in an easy-to-understand way—GDPR-compliant, technically sound, and aligned with your business goals.
Clean setup,
reliable data
GDPR-compliant and
data protection-certified
Data that leads to decisions—not just reports
Balancing Privacy and Analytics
GDPR-compliant tracking is not at odds with high-quality data. It simply requires a well-thought-out setup: proper consent management, server-side tracking, and a clean configuration of the tools used. We’ll set up your analytics so that only the data you actually need—and are permitted to collect—is gathered. Combined with conversion optimization, this creates a data-driven cycle: measure, understand, improve. We’ll provide your data protection officer with the relevant documentation.
Measuring What Matters
Traffic alone doesn’t tell you much. What matters is where your visitors come from, what they do on the website, and where they leave. We’ll set up your tracking to answer these questions. Every event, every conversion, and every click is accurately recorded and assigned to a channel. For SEO, Google Ads, and content marketing, this provides the foundation for evaluating strategies and allocating budgets effectively. Without reliable data, any optimization is just a guessing game.
Web analytics involves more than just installing Google Analytics. From tag management to conversion tracking to a setup that complies with data protection regulations: Every component must be configured correctly so that the data is accurate and supports decision-making.
These companies know how we work
GA4 is the standard for web analytics, but how it’s configured determines the value of the data. We set up GA4 properly from the ground up: property structure, data streams, event tracking, and conversion definitions. Custom events track the actions that are relevant to your business—not just page views. Audiences and segments help you analyze specific user groups. For Google Ads, we set up the integration so that campaign data flows directly into GA4. We build explorations and custom reports tailored to your questions: Which pages convert best? Which traffic sources bring in qualified visitors? We regularly check data quality and clean up spam traffic, duplicate events, or incorrect configurations. This ensures that GA4 delivers reliable figures you can count on. An analytics and tracking agency spends most of its time on this work—not just on the dashboard.
