How we work

Clear answers to the questions brands ask us most often.

More from existing traffic

Often, optimizing the site delivers more than additional traffic. We first check where visitors are lost.

Testing instead of guessing

Tests end debates. We design them to ensure results are meaningful.

Sufficient data

With low traffic, classic tests are difficult. We will tell you honestly when other methods are better.

Understanding users

Numbers show what, observation shows why. We use both.

Approach and decision criteria

  1. 01

    Initial meeting

    We clarify objectives, target group, offer, and framework, and check if paid ads are the right lever.

    Result: Clear objective definition and assessment.

    From you: Objective, offer, and previous experience with ads.

  2. 02

    Setup & Tracking

    We set up accounts, audiences, and measurement so that results can be clearly attributed later.

    Result: Clean account and measurement setup.

    From you: Access to ad accounts, website, and shop.

  3. 03

    Campaign launch & testing

    Ads and creative variants go live; we test systematically instead of guessing.

    Result: Ongoing campaigns with a test plan.

    From you: Approval of budget limits and creatives.

  4. 04

    Management & reporting

    We make adjustments, shift budget to what works, and report at fixed intervals.

    Result: Reporting with concrete recommendations.

    From you: Feedback on leads or sales from your perspective.

Measuring success & limitations

Inquiries, purchases, and abandonment rates show impact. We define in advance how we will measure them.

Limitations: With CRO, offer, competition, site, and budget all influence results. We state upfront what is realistic and do not guarantee outcomes.

Questions before commissioning

What is CRO?

Conversion rate optimization: measures that increase the share of visitors who make an inquiry or purchase.

How much traffic do I need for A/B tests?

Enough to ensure results are meaningful. With low traffic, we use other methods.

How quickly will I see results?

Tests require time to run. We plan for this and evaluate results thoroughly.

How does the collaboration work?

Consultation, analysis, hypotheses, tests, and implementation.

Do you work with our shop system?

Usually yes. We clarify the options in the initial consultation.

What affects the effort involved?

Traffic, number of pages, technology, and test depth. We clarify this in the initial consultation.
