“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 Digital Experience & Data
Ensuring every interaction leaves a lasting, positive impact
While most commonly known as Conversion Rate Optimisation (CRO), we prefer to focus on what we call Digital Experience Optimisation (DXO). Thats because it goes beyond simply increasing your conversions; it enhances every part of the user journey, ensuring each interaction with your brand is meaningful and drives long-term success.
Exceptional experiences aren’t just nice to have—they’re what build trust, loyalty, and long-term growth.
From first click to final checkout, every touchpoint matters. The brands winning today? They’re the ones constantly testing, learning, and improving. If you want to stand out (and stay there), continuous optimisation isn’t optional—it’s the playbook.
“It wasn’t about website overhauls or guesswork, it was about stacking small, smart wins driven by data.”

Boosting conversions & supercharged paid funnels
While paid media brought the traffic, we made sure the on-site experience did the heavy lifting. We dug into user behaviour, spotted where people were dropping off, and fixed what was tripping them up. That meant A/B testing sharper headlines, cutting the faff from quote forms, and tightening layouts to make pages flow better.
We also dialled up trust—more proof, clearer value, fewer doubts.
The result? Higher conversion rates, better lead quality, and more value from the same ad spend—even as CPCs wobbled.

CRO Programmes
Real growth isn’t built on isolated wins. That’s why Proof3’s DXO programmes are built to deliver continuous, compounding improvement, not one-off fixes. We work as an extension of your team, creating ongoing testing roadmaps, setting clear priorities, and adapting as your business evolves. Our programmes bring together audits, experimentation, data insights, and user feedback into a focused system that drives sustained results. We don’t just optimise pages; we optimise thinking, helping your business make smarter decisions at every stage of the customer journey.
Key benefits
Data & Attribution
Good decisions start with good data. We ensure every test, tweak, and tactic is tied to clear, reliable measurement. We set up robust data frameworks and attribution models that cut through noise, showing you not just what happened, but why. Whether it’s tracking user behaviour, measuring lift from experiments, or connecting conversions back to source channels, we build the systems that turn analytics into action. We give you the clarity to invest in what works and cut what doesn’t with absolute confidence.
Key benefits
Feedback & NPS
Numbers tell you what’s happening. Your users tell you why. 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.

In an age where digital interactions are abundant, “best practices” no longer cut it. Brands today must make decisions rooted in first-party data, real customer insights, and methodical testing
Overhauling a website might seem like a logical step for modernisation, but without user feedback, it can quickly backfire.
Surveys are a fantastic way to gather feedback, but incentives don’t always lead to honest answers.
Website search is often overlooked but plays a massive role in guiding customers to the products they need. A well-optimised search function can increase conversion rates by up to 50%, yet many businesses fail to utilise it effectively.
One of the simplest ways to speed up your Shopify store is to optimise your images.
