“It’s not just about squeezing more conversions—it’s about building a digital experience your customers actually enjoy using. That’s what drives real growth.”
Tiago Faustino
Head of Conversion Rate Optimisation
Ensuring every interaction leaves a lasting, positive impact
That’s why we focus on Digital Experience Optimisation (DXO), not just Conversion Rate Optimisation (CRO). DXO goes beyond simply increasing conversions; it enhances every part of the user journey, ensuring each interaction with your brand is meaningful and drives long-term success.
Delivering a remarkable digital experience is key to building stronger connections with your customers. It’s not just about boosting conversions but ensuring every interaction leaves a lasting, positive impact. By enhancing each stage of the customer journey, your brand becomes more memorable and trusted, driving both loyalty and growth. If you want to stay ahead in a competitive market, ongoing experimentation and optimisation are essential for continued success.
“It wasn’t about website overhauls or guesswork, it was about stacking small, smart wins driven by data.”

Case study – Improving conversions and paid funnels
Alongside paid media, we focused heavily on CRO to make sure every visit had the highest possible chance of converting. We started by analysing user behaviour across key landing pages, identifying drop-off points and confusion triggers. From there, we ran a series of A/B tests reworking headlines to highlight key benefits faster, simplifying quote forms to reduce friction, and tightening up page layouts to make navigation feel intuitive. We also leaned into trust-building elements like social proof and clearer value messaging, especially around pricing and cover benefits.
The impact was immediate. Conversion rates climbed, meaning we didn’t just maintain lead volumes, we improved them, even as cost per click fluctuated. Because the site was working harder, the same ad spend started delivering more value.

Feedback & NPS
Numbers tell you what’s happening. Your users tell you why. At Proof3, we integrate qualitative feedback and Net Promoter Score (NPS) insights into every optimisation programme. By listening carefully to your customers ‘ frustrations, motivations, and unmet needs, we add a critical human layer to the data. Feedback loops help us refine hypotheses, personalise experiences, and prioritise improvements that matter most. Combining behavioural analytics with real customer sentiment means we’re not just chasing clicks; we’re building experiences that convert, delight, and drive loyalty.

Stop Guessing. Start Growing.
Most website changes are based on gut feel, opinion, or copying what competitors are doing. That is the reality, and it is risky. Features and designs get shipped without anyone truly knowing if they are helping the user or hurting your revenue. Even the best instincts are often wrong because understanding your customer’s real journey, in that exact moment, on your site, with your brand, is incredibly hard. CRO cuts through the guesswork. It gives you clarity, not opinions. We help brands make decisions backed by real user behaviour, not gut feel, so every change drives genuine growth, not hidden losses.
Delivering a remarkable digital experience is key to building stronger connections with your customers. It’s not just about boosting conversions but ensuring every interaction leaves a lasting, positive impact. By enhancing each stage of the customer journey, your brand becomes more memorable and trusted, driving both loyalty and growth. If you want to stay ahead in a competitive market, ongoing experimentation and optimisation are essential for continued success.
Best Practices Are Not Enough Anymore
One size fits all thinking does not work anymore. Your users, your website, your brand, your industry, they are different, and they behave differently. There is no consistent rulebook that guarantees results. Adding features or making changes based on gut feel or what worked elsewhere is not enough. With so many different digital experiences today, you cannot assume what works for one brand will work for yours. The only answer is to test. Methodical testing protects your business from costly mistakes that can quietly drain your revenue over time. We have seen it happen, businesses launch beautiful redesigns only to realise months later they lost customers because they did not validate changes with real users. Design and opinions might win awards, but data wins customers. Without it, you are flying blind.
