About the service
We increase conversion rates on landing pages, shops and sign-up funnels through structured experimentation. The process runs from quantitative analysis and session recordings to hypothesis, A/B test and rollout. Every result is validated statistically before it is called a win, and losing tests are documented just as carefully as winning ones.

Challenges we solve
- #1
Traffic is expensive and the page converts at under one percent.
We diagnose first: where do people stop scrolling, which form field kills the session, which promise is missing. Then we rebuild the page around the strongest motivator and test it against the original.
- #2
The team runs A/B tests but the results contradict each other every month.
Usually the tests are stopped too early. We calculate the required sample size in advance, run a fixed duration covering full weekly cycles and only then evaluate.
- #3
Checkout abandonment is high and nobody knows at which step.
We instrument each step as an event, add form field analytics and identify the exact input where people leave, usually shipping costs, payment method or a mandatory account.
- #4
Traffic volume is too low for a statistically valid A/B test.
We switch to qualitative methods: five-second tests, moderated sessions, customer interviews and sequential before-after comparisons with clear guardrails, and change bigger things at once instead of details.
LPO/CRO optimization
A one point gain in conversion rate has the same effect as a proportional increase in media budget, but it does not recur as a monthly cost. We prioritise experiments by expected impact, confidence and effort, and run them where traffic volume can actually reach significance. You receive a test backlog, the running experiments with live results and a documented library of learnings that stays useful long after the engagement.

Frequently asked questions
A one-off conversion audit with a prioritised backlog starts at 1,500 EUR. Ongoing experimentation including design, implementation and analysis is from 1,900 EUR per month.
For classic A/B testing, roughly 1,000 conversions per month across the funnel gives reliable results within two to three weeks per test. Below that we use qualitative methods and larger changes.
GA4 and a warehouse for analysis, Hotjar or Microsoft Clarity for recordings, and server-side or edge experimentation for the test itself, which avoids the flicker effect of older client-side tools.
Yes, we design and implement the variants and hand a clean pull request to your developers for the winning version, or deploy it ourselves if we maintain the site.
They run only after consent, with automatic masking of all input fields and suppression of personal data. We configure the tool accordingly and document the setup for your records.
