Digital Marketing: Data Analytics and Conversion Rate Optimization

Data Analyticsand Conversion Rate Optimization

Data is only as valuable as the decisions it drives. We help you set up clean tracking, understand how your visitors actually behave, and systematically turn the right dials to move your conversion rate. Whether it's checkout optimization, landing page testing, or full-funnel analysis — we work methodically, with data as the backbone and more completed actions from the same traffic as the goal.

Challenges you'll recognise

  • You see a lot of numbers in your analytics reports but can't translate them into concrete actions.
  • Your traffic is growing but your conversion rate is stagnating — and you don't know where in the funnel visitors are dropping off.
  • You make changes to your website based on gut feeling and can't prove afterwards whether they made a difference.

Services in detail

Good to know

  • Tracking quality drives decision quality

    Incorrectly configured tracking produces data that looks trustworthy but leads to wrong conclusions. Before optimisation makes sense, the foundation — a valid data setup — needs to be solid.

  • Small changes, real impact

    CRO doesn't work through large redesigns but through systematic testing of individual elements: headline, CTA position, form fields, page structure. The true effect of small changes can often only be confirmed through proper testing.

  • Statistics before intuition

    A/B tests must reach statistical significance before conclusions are drawn. Tests stopped too early are a common source of error — they suggest a winner where none actually exists yet.

Frequently asked questions

What's the difference between web analytics and conversion rate optimization?
Web analytics is the measurement and interpretation of user behavior — it supplies the data. Conversion rate optimization (CRO) is the systematic testing and improvement of the site based on that data. They belong together: analytics without optimization stays theoretical, optimization without valid data is guesswork.
Do I need Google Analytics 4, or will another tool work?
GA4 is the standard and offers the best integration with Google Ads and Search Console. We also implement Matomo, Plausible, or other privacy-friendly alternatives — particularly relevant for companies with strict GDPR requirements. What matters most is that tracking is complete and valid.
How much traffic do I need for A/B tests to be meaningful?
As a rule of thumb, statistically reliable A/B tests need at least 500–1,000 conversions per variant per test. With lower traffic volumes, we focus on direct UX improvements and heatmap analysis rather than classical A/B testing.
Do you only optimize the website, or the shop checkout process as well?
Both. The checkout is often the most critical funnel step — small changes here have the largest impact. We analyze abandonment points, test multi-step versus single-page checkout flows, and optimize trust signals like reviews and payment options.
How long does a typical CRO engagement last?
CRO is not a one-off project — it's an ongoing process. We recommend a continuous retainer model with monthly test cycles. Focused sprint engagements — such as before a major launch or ahead of peak season — are also possible.
