Are you familiar with these problems?

The symbols for the numbers from your tracking are simply incorrect.

Incorrect data in reporting.

The numbers from tracking don’t match the shop backend? Orders are missing, events fire twice or not at all—and no one knows what the data really means.

Symbol for them lack clarity about which KPIs are really important to you.

Unclear KPI definitions.

You lack clarity about which KPIs are really important. Conversion rate, cart-to-detail, revenue per visitor? You see lots of numbers—but what do they actually mean for your business?

Symbol for decisions based on gut feeling rather than data.

Decisions without foundation.

Because the data basis is uncertain, many things remain unclear. Optimizations are not prioritized or are delayed because there is a lack of confidence in the figures.

Any questions about Quick Win?

Here we answer the most important questions about the process, results and your investment – transparently and concisely.

Why do my e-commerce figures in Google Analytics not match those in the shop system?

Diskrepanzen zwischen Shop-Backend (ERP) und Analytics-Daten entstehen oft durch technische Messfehler, Ad-Blocker, Consent-Probleme (Cookie-Banner) oder doppelte Zählungen. Wir gleichen Ihre Bestellungen direkt ab, prüfen die “Data Layer” und identifizieren die genauen Fehlerquellen, um die Lücke zu schließen.

Our process is designed for efficiency. From gathering requirements to presenting the results and the finished dashboard, we typically need 10 days.

That depends on your business model. Instead of “vanity metrics” (such as pure page views), we focus on actionable KPIs such as customer lifetime value (CLV), return on ad spend (ROAS), conversion rate by device type, and shopping cart abandonment rates. Together, we define what matters for your success.

Yes. We don’t just provide data, we provide solutions. You receive a prioritized list of measures (backlog) that your IT department or agency can work through directly. We also train your team so that you can identify errors yourself in the future.

The Looker Studio Dashboard serves as a central, easy-to-interpret hub for all business-relevant KPIs of your online store.

It visualizes your performance funnel and e-commerce KPIs and provides analyses by channel or device type. In addition, you will receive practical training in which we teach your team how to use the dashboard independently, interpret data correctly, and thus make informed decisions in day-to-day business.
