What Is Conversion Rate Optimization?

CRO is the process of getting more of your existing visitors to do what you actually want — buy something, sign up, request a demo. It combines analytics, user research, and A/B testing to find where your funnel breaks down and fix it with something that works better. The compounding effect is real: each improvement makes every future visitor worth more.

Waar projecten falen

You're spending $50K+/month on paid acquisition and your landing pages are converting below 2% Every month you wait is budget that could be generating 30-50% more revenue.
Your SaaS trial-to-paid conversion is stuck under 5% and you can't pinpoint why Competitors with tighter onboarding are scooping up the same leads at a lower CAC.
Product and marketing can't agree on what to change, so decisions come down to whoever argues loudest You ship a redesign that looks great, it performs worse, and you've just burned weeks of engineering time.
Cart abandonment is sitting above 70% and your recovery emails aren't doing much You're hemorrhaging revenue at the last step while spending more to fill the top of funnel.
You've never run a statistically valid A/B test — changes just ship You can't tell what's working from what's noise, so regressions slip through unnoticed.
Mobile converts at half the rate of desktop, but 60% of your traffic is mobile You're essentially paying double for every mobile visitor.

Compliance

Full-Funnel Analytics Audit

We instrument your entire funnel with event tracking and identify exactly where users drop off. You get a prioritized list of leaks, ranked by revenue impact.

Heatmap & Session Recording Analysis

We deploy Hotjar or PostHog to record real user behavior — clicks, scrolls, rage clicks, dead zones. Those patterns go straight into our test queue as hypotheses.

Hypothesis-Driven A/B Testing

Every experiment starts with a written hypothesis, an expected lift, and a statistical power calculation. We run tests in Statsig or PostHog and don't call results until they're valid.

Landing Page Redesign & Build

We design and build high-performance landing pages in Next.js, tuned for Core Web Vitals and conversion. No drag-and-drop templates — actual engineering.

SaaS Onboarding Optimization

We map your activation flow, find time-to-value bottlenecks, and test changes to onboarding steps, empty states, and upgrade prompts. The goal is getting more users to their aha moment, and getting them there faster.

Ecommerce Checkout Optimization

We tackle cart abandonment through checkout simplification, trust signal placement, payment option expansion, and shipping cost transparency testing.

Wat we bouwen

Quantitative Funnel Analysis

Segment-level drop-off analysis across acquisition channels, device types, and user cohorts — so you know exactly where revenue's leaking and why.

Qualitative User Research

Five-second tests, user interviews, and surveys to understand the why behind what behavioral data shows.

Rapid Prototyping in Figma

Interactive prototypes for stakeholder alignment before any code gets written. Kill bad ideas early, deliberately.

Server-Side A/B Testing

Flicker-free experiments rendered at the edge, so testing doesn't degrade page performance or skew your results.

Revenue Attribution Reporting

Monthly reports tied to incremental revenue — not click-through rates or other metrics that don't pay the bills.

Continuous Test Velocity

We keep a prioritized backlog and ship 4-6 tests per month, stacking gains quarter over quarter.

Veelgestelde vragen

Hoe lang duurt het voordat we resultaten zien van CRO?

De meeste klanten zien hun eerste statistisch significante resultaat binnen 4-6 weken. Betekenisvolle omzetimpact bouwt zich meestal op over 90 dagen naarmate winnende tests zich opstapelen. Hoe snel dat gebeurt hangt af van je verkeersvolume — meer verkeer betekent snellere significantie en snellere iteratie.

Wat is het minimale verkeer dat nodig is voor A/B-testen?

Je wilt minstens 10.000 maandelijkse bezoekers naar de pagina's die je test. Onder dat aantal duren tests te lang om significantie te bereiken. Voor sites met lager verkeer gebruiken we user testing, heuristische analyse en sequentiële testen om vooruitgang te boeken zonder maanden op data te wachten.

Werken jullie met onze bestaande analytictools?

Ja. We werken met GA4, Mixpanel, Amplitude, PostHog, Segment en de meeste grote analyticsplatformen. Als je tracking hiaten heeft — en dat is meestal het geval — repareren we instrumentatie tijdens de audit. We zullen tools aanbevelen die in je stack passen, niet in de onze.

Hoe verschilt CRO van een websiteherdesign?

Een redesign vervangt alles tegelijk op basis van gissingen. CRO test individuele veranderingen tegen je huidige baseline en stuurt alleen wat aantoonbaar beter presteert. Redesigns schaden conversie vaak omdat tegelijk te veel variabelen veranderen. We pleiten voor incrementele, evidence-based verbeteringen in plaats daarvan.

Wat als een test verliest — betalen we dan nog steeds?

Ja, maar verloren tests zijn niet verspild. Ze voorkomen dat je iets stuurt wat de omzet zou hebben geschaad, en ze genereren echte inzichten voor de volgende test. Onze taak is het uitvoeren van een groot volume goed doordachte experimenten. Branche win rates liggen rond 20-30% — we halen consistent 35-40%.

Kunnen jullie onze SaaS onboarding flow specifiek optimaliseren?

Absoluut. SaaS onboarding is een van onze kernfocusgebieden. We brengen je activation funnel in kaart, vinden waar gebruikers afhaken voordat ze hun aha-moment bereiken, en testen veranderingen in onboarding-stappen, lege toestanden, tooltips, e-mailsequenties en upgrade-prompts. Trial-to-paid conversie is meestal de meest impactvolle metric waar we aan werken.
