Sound familiar?
We get plenty of visitors, but they don't convert.
I have no idea where people drop off on our website.
We invest in traffic, but leave leads on the table.
How we help
We uncover where and why visitors drop off, and use research and A/B testing to increase the percentage that enquires or buys.
Why Customer Impact
We start from what the numbers and visitor behavior show, not from an opinion about a color or a button.
We validate changes with A/B tests, so you know for sure what makes the difference and what is coincidence.
We combine quantitative data with user insight to understand why visitors drop off.
We steer on enquiries and revenue, not on micro-metrics that look good but deliver nothing.
About Customer Impact
Customer Impact is a digital marketing agency founded by Tanguy De Keyzer. For more than 10 years we have been building the growth engine of startups, scale-ups and established companies.
Our conversion optimization is data-driven and connected to your entire funnel: we don't just lift a percentage, we lift the revenue that flows from it.
What we stand for:
What we do
We track down where visitors drop off and why, on every key page.
Heatmaps, session recordings and data reveal real behavior, not assumptions.
We test variants against each other and let the numbers decide, not gut feeling.
A clear message, a strong call-to-action and less friction in the process.
We improve every step from first visit to submitted enquiry.
Many small wins compound into large, lasting growth.
Our process
We map out where and why visitors drop off, using data and behavioral research.
We formulate evidence-based hypotheses with the biggest impact on your conversion.
We set up A/B tests to prove what really works.
Winning variants go live; losing ones still deliver insight.
Conversion optimization is a cycle, not a one-off fix. We keep improving.
Many companies keep investing in more visitors while the real leak sits on the site itself. If visitors arrive but don’t convert, you are pouring water into a leaking bucket. Conversion rate optimization plugs that leak. Especially now that AI answers can siphon off part of your clicks, getting more out of the visitors who do reach your site counts double.
That is where we excel. We made Get Driven’s conversion rate four times as high (from 1.8% to 7.3%), increased Adventure Valley’s mobile conversion by 300% and Aikido Security’s conversion rate by 25%, each time from the traffic that was already there.
A beautiful page is not the same as a converting page. We install a measurement ecosystem, pinpoint exactly where people drop off and why, and test improvements one by one.
That way we know for certain what works. No opinions, just proof. And every win we find keeps paying off, day after day.
Conversion optimization doesn’t stand alone. A higher conversion rate makes every euro you put into Google Ads, SEO and lead generation instantly more profitable, because the same traffic now produces more enquiries. And a fast, clear website is the foundation every test builds on.
That is why CRO is often the smartest first investment: it multiplies the return on everything you are already doing. Ready to get more out of your current traffic? Contact us.
CRO is the cheapest growth there is, because you get more out of traffic you are already paying for. The gains are rarely in prettier buttons, but in removing doubt and friction at the decisive moment.

Case studies
Europ Assistance wanted to prove which changes on the site really deliver more conversion. We tested the homepage, a product page and the checkout with A/B tests, and all three tests won. On the product page conversion per user rose by 11%, from 16.5% to 18.4%.
Aikido Security attracted visitors, but converted too few of them into enquiries. We sharpened the content and the CTAs on the landing page and tested different versions against each other. The conversion rate rose by 25% and the average time on the page by 15%.
Read the caseAt Adventure Valley Durbuy, mobile visitors dropped off in the checkout process. We simplified the mobile checkout with fewer steps and fixed the technical SEO. The mobile conversion rate from first click to purchase rose by 300%.

Often a lot. Our clients saw anything from +25% more conversion to a fourfold conversion rate from the same traffic. Double your conversion rate and you double your results without extra ad budget.
Volume helps for reliable A/B tests, but even with less traffic we deliver gains through user research, clear messaging and proven best practices.
Conversion rate, cost per lead and ultimately revenue. We steer on results that matter to your business, not just clicks.
CRO runs as an ongoing program or as a one-off conversion audit; pricing depends on scope, so ask us for a proposal. The gains often pay for themselves quickly, because you get more out of traffic you are already paying for.
A first audit delivers concrete improvements within a few weeks. A/B tests then run in cycles of a few weeks per test, and the wins compound.
For B2B and B2C sites with enough traffic and a clear conversion (enquiry, demo, purchase). Even with less traffic we deliver gains through user research and proven best practices.
Data analysis, UX/UI and technical SEO for a smoother mobile booking flow.
Focused content, clear CTAs and A/B tests on a landing page.
Three CRO experiments from homepage to checkout, each with an A/B test.
