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.

Google Analytics 4

The standard tool for web analytics. We set up GA4, configure events and conversions, and build reports that answer your questions—from basic installation to custom reports and audiences.

Tag Management

Google Tag Manager or Matomo Tag Manager: We manage all tracking codes centrally and efficiently. Add new tags, modify existing ones, or remove outdated ones—all without requiring developer intervention on the website.

Conversion Tracking

Forms, calls, downloads, purchases: We track every conversion and attribute it to the right channel. That way, you'll know which strategies are delivering results and where your budget is being wasted.

Data Protection-Compliant Tracking

Cookie banners, consent management, and server-side tracking: We ensure that your tracking complies with GDPR requirements. Includes documentation for your data protection officer.

Dashboards and Reporting

Data is only useful when it's presented in a way that's easy to understand. We build dashboards in Looker Studio or using our own tools that clearly display your KPIs. Automated reports are sent monthly via email.

Heat Maps and User Behavior

Where do your visitors click? How far do they scroll? What do they overlook? Tools like Hotjar or Microsoft Clarity show how your website is actually being used. The results inform design and content decisions.

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.

Audit and Assessment

We’ll review your existing tracking setup: Which tools are installed? Are the tags working properly? Are conversions being tracked? Is the setup GDPR-compliant? The audit provides a clear overview of the current status and highlights areas where action is needed.

Strategy and Measurement Plan

Together, we’ll determine what data you need and which KPIs are relevant to your business. This will result in a measurement plan: Which events will be tracked? Which conversions will be defined? Which dashboards will be built? The measurement plan serves as the blueprint for the entire setup.

Implementation

We implement the measurement plan: GA4, Tag Manager, conversion tracking, consent management, and, if applicable, heatmap tools. Every tag is tested, and every conversion is verified. The setup is documented so that you and your team can understand what is being measured and where.

Dashboard and Reporting

Based on the data we collect, we build your dashboards and automate your reports. From now on, you’ll be able to see at a glance how your website is performing. The dashboards are tailored to your specific needs and regularly updated to meet new requirements.

Ongoing Optimization

Tracking isn’t a one-time project. We regularly check to make sure all events are firing correctly, that new pages or features are being tracked, and that the data quality is up to standard. If your website or your goals change, we’ll adjust the setup accordingly.
