CRO Agency for E-Commerce

A CRO agency is easy to find. Most of them sell hours, tickets or tool access. We sell something else: a conversion optimisation system that measurably grows revenue — or you pay nothing. No setup fee, no risk, 10% of the revenue increase we can prove.

Conversion optimisation as a system, not an agency toolkit

Most agencies treat conversion rate optimisation as a project: a redesign here, a button there, a report at the end. The problem: isolated measures produce isolated results that drown in the noise. We build a testing system instead — one that generates hypotheses every week, tests them, and feeds the results into the next experiment. When you start with us, you don’t get a toolkit. You get a process that doesn’t stop.

The difference shows in the questions. A task agency asks: “What should we change?” We ask: “Where do your visitors lose trust, money and patience — and which hypothesis proves the opposite?” The first test goes live 3–5 working days after onboarding.

Scope: what a CRO agency must deliver

CRO is neither a design job nor an analysis job. It is both, plus the discipline to test. Our scope covers the three layers where conversion actually happens:

A testing programme, not single tests

We run a continuous experimentation programme: research, hypothesis prioritisation, A/B-tests, evaluation, implementation. Not one test per quarter, but a system that delivers decisions every week. How that programme is built is explained on our page about A/B-testing as a service.

Checkout, product page, category

Three places decide the revenue of an online shop: the product page (does it get the click?), the category (does it get found?) and the checkout (does it get paid?). We optimise all three — not as a redesign, but as a sequence of tested, proven improvements. The fundamentals are covered in our guide to conversion rate optimisation.

Research + analytics

Every hypothesis has a data basis. We combine quantitative analysis (funnel data, segmentation, heatmaps) with qualitative research (session recordings, user feedback). Testing without research means testing opinions.

How we work

Our approach is the JDKRUEGER&CO model: a fixed system of analysis, hypothesis, test and implementation. You always know which test is running, why it is running and what it is supposed to prove. The results belong to you — documented and traceable, whether a test wins or loses.

Billing follows the same principle: 0 € setup, 10% of the provable revenue increase. No monthly retainer for activity, no cost for tests without impact.

Proof: what the system does in practice

We don’t quote numbers here, because every shop is different. Instead, we point to documented cases — anonymised, but structurally complete:

• Testing system for a gift shop — from single tests to a running experimentation programme.
• Mobile checkout optimisation — leverage on the device where most shops lose.
• CRO system for a natural products shop — system instead of gut feeling.
• Trust optimisation in precious metals — why trust is the hardest conversion hurdle.

All cases show the same pattern: the additional revenue doesn’t come from one winning test, but from the sum of a system that never stops testing.

Who we work for — and who we don’t

We are the right CRO agency if you run an established online shop, have enough traffic for statistically valid tests, and are willing to let data make decisions instead of taste.

We are not right if you are looking for a relaunch that should “look fresh”, if your shop doesn’t have meaningful visitor numbers yet, or if you need an agency that executes whatever was discussed in a meeting without pushback. In that case, a classic full-service agency will serve you better.

Still researching and mainly wondering what CRO costs and how to compare agencies? Our page on choosing a CRO agency and its costs is the right next step.

How we start

Three routes, depending on where you are:

• Book a call — a direct conversation, no sales show, a clear assessment of whether your shop fits our model.
• CRO ROI calculator — in a few inputs you see the revenue potential sitting in your current numbers.
• Shop audit — we analyse your shop and show you the three biggest conversion levers before you commission anything.

Common questions about working with a CRO agency

What distinguishes a CRO agency from a regular online marketing agency?

A CRO agency optimises one thing only: the share of visitors who buy. It tests changes against real users instead of simply implementing them. Marketing agencies buy traffic; CRO agencies turn existing traffic into more revenue. CRO is our only business, not an add-on module.

When does a CRO agency pay off?

When your shop has enough traffic to evaluate A/B-tests statistically — in practice from roughly 1,000 visitors per week. Below that, test durations stretch so much that a testing programme is barely faster than solid research. If you are unsure, the first call will tell you within minutes where you stand.

What does working together cost?

0 € setup. Then 10% of the provable revenue increase — measured by A/B-tests or before/after comparisons. No extra revenue, no cost. Details and pricing examples are on the pricing page.

How fast will I see results?

The first test goes live 3–5 working days after onboarding. Measurable revenue impact typically shows within the first month — but the system only really compounds from the second quarter, because every test improves the quality of the next hypotheses.

Do you work with our existing agency or shop system?

Yes — that is the normal case. We are the CRO specialists; your agency stays responsible for shop, design and development. Platform-specific experience covers Shopify, Shopware, WooCommerce and Magento.
