Does more traffic = more sales?
Most businesses focus on getting more traffic. More clicks, more visitors, more impressions. But the truth is, none of that matters if those visitors don’t convert.
Everyone says they do things differently. We just do it smarter—by turning traffic into revenue through a deep understanding of what makes your users tick. Because profitable growth doesn’t just come from getting more people to your site, it comes from making sure the right people get to your site and take the right actions when they get there.
More value from your existing visitors – No more wasted traffic.
Higher ROI & Lower CPA on paid spend – Every click should count.
Smarter experiences on site & beyond – Built for conversions, not just looks.
You don’t want guesswork. You want proof. The more we test, the more we learn—so you get faster growth backed by evidence, not opinion. That is the core principal of Proof3.
“Thanks to Proof3’s thorough review and analysis of our website and user experience, our conversion rate increased from 1.2% to 2% over a 6 month period”
Amber Domenech – Head of eCommerce – Goddiva
Goddiva are a fast-growing ladies fashion brand, selling through their own website and throughout UK nationwide retailers.
While they’d been enjoying significant growth year on year through their own Shopify store, they came to us with a challenge to increase AOV and conversion rate to maximise the ROI from their marketing spend.
Proven wins:
“We’ve been working with Proof3 for 18 months and we’ve achieved more in that time than we did in the three years with our previous agency….”

Can we help you grow online? Let’s find out …
Most businesses start with a grand vision. Ours? It started with a frustration.
We’ve spent years working in the digital space, watching businesses pour money into projects – decisions driven by speculation rather than evidence. The problem isn’t a lack of effort or a desire for results; it’s a lack of proof. Without clear insights and feedback, businesses are flying blind, unsure whether their decisions are moving them forward or holding them back.
What if, instead of relying on gut instinct or so-called best practices, businesses made decisions based on real data? What if we could take the uncertainty out of growth?
That’s where Proof3 was born. From day one, our mission was clear: create new standards in digital experience driven by data, not opinions.
Expert-led CRO that hunts down hidden blockers, taps into raw customer insight, and fuels faster, data-backed wins—so you can test smarter, convert more, and unlock real eCommerce growth.

Proven performance wins
At Proof3, we work with businesses that are done making decisions based on opinions and best guesses. If you’re looking for an agency to nod along and execute whatever’s on your wishlist, that’s not us.
But if you want a partner who will challenge assumptions, analyse data, and uncover what actually drives growth, you’re in the right place.
The brands we do our best work with:
Want clarity, not clutter. They don’t just want more traffic or leads; they want the right ones that convert, and they want to know exactly why.
Care about outcomes, not noise. They don’t chase vanity metrics or the latest fads. They want meaningful growth, and they trust us to help them achieve it.
Make decisions based on evidence. They know that success isn’t about following trends; it’s about testing, learning, and optimising what actually works.
Put experience at the centre. A great customer experience isn’t just nice to have; it’s what drives conversions, loyalty, and long-term success.

Accelerating Revenue Growth
Our ultimate goal is more sales, not just more traffic. We look at each stage of your funnel to see where people drop off—whether it’s a landing page or a checkout flow—and then systematically test improvements. Each experiment is driven by a clear hypothesis about how it’ll lift your conversion rate and, by extension, your revenue. Once we prove something works, we roll it out so you see real growth.
It depends on factors like your traffic volume and the complexity of your tests. That said, we’re able to launch initial experiments within a few weeks of kicking off a project. If a test shows a significant lift, you’ll start reaping the rewards as soon as the winning variation goes live.
We don’t rely on a one-size-fits-all playbook. We analyze your specific audience—through qualitative and quantitative data—and tailor our experiments accordingly. What works for a retail brand might differ from a SaaS business. Our approach ensures you get strategies that suit your unique market segment, rather than a generic template.
Demonstrating Clear ROI
We’re laser-focused on outcomes. Our team sets measurable goals—like boosting average order value or lead-to-customer conversions. We track these metrics meticulously and provide transparent reporting. That way, you’ll see exactly how each test translates into revenue gains or lower acquisition costs.
Think of CRO as maximizing every dollar already going into your traffic. If you’re investing in paid ads, SEO, or social media, you’re driving people to your site. CRO amplifies the impact of that spend by converting more visitors into customers. It’s a multiplier effect that improves the efficiency of all your other marketing investments.
We set clear expectations and a defined scope of work up front. You’ll know exactly where our hours are going and why. Any new initiatives or changes are discussed ahead of time. That keeps surprises to a minimum and ensures you always know the value you’re getting.
Respecting Your Team’s Time
We design our process to handle most of the heavy lifting. We do need some initial access to your analytics platforms and brand guidelines. After that, you can be as hands-on or hands-off as you like. We’ll regularly share progress, but we won’t overwhelm your inbox unless you want more frequent updates.
We use sprint-based planning. Each sprint has specific goals, timelines, and deliverables. We check in at regular intervals to address roadblocks early. If a priority changes on your end, we adjust the roadmap rather than letting it stall progress. This structure keeps everything moving forward predictably.
We rely on short, focused cycles of testing instead of massive, drawn-out initiatives. This approach not only keeps the project manageable but also delivers wins incrementally. If something isn’t working, we know fast and can pivot quickly—meaning we avoid big delays and stay nimble.
Ensuring a Smooth Partnership
We build flexibility right into our process. If a new product launch or campaign pops up, we’ll recalibrate our testing queue accordingly. Because we work in shorter sprints, we can switch gears without derailing the entire engagement.
It depends on factors like your traffic volume and the complexity of your tests. That said, we’re able to launch initial experiments within a few weeks of kicking off a project. If a test shows a significant lift, you’ll start reaping the rewards as soon as the winning variation goes live.
We assign a core strategy lead and a dedicated point of contact to your account. While we may involve other specialists for specific tasks (like UX design or analytics deep dives), your main contact remains consistent. This structure keeps everyone on the same page and prevents any “musical chairs” confusion.
Too much tech, not enough clarity? We cut through the noise—connecting you with proven partners and helping you build the right stack for your business.
