A CRO agency that turns the traffic you already have into revenue
Most stores do not have a traffic problem. They have a conversion problem. We find where your Shopify store loses customers, fix it in order of revenue impact, and prove every change with a test. Our Lioness relaunch lifted conversion rate 74% and sales 113% year on year, and won Shopify's 2026 Build Award for Merchant Impact.
Evidence, not opinion
Results that compound
How does conversion rate optimisation work at Prosper?
Conversion rate optimisation is the discipline of getting more customers from the visitors you already pay for. We find where your Shopify store loses customers, fix it in order of revenue impact, and prove every change with a test. Start with a CRO audit, or read about how we work with brands after launch on an ongoing partnership.
More revenue from the same traffic
CRO is the highest-return lever in ecommerce because it improves every channel at once. Paid, organic, email and social all convert better when the store does.
Evidence, not opinion
Every recommendation is grounded in your data and your customers' behaviour. We test hypotheses with real traffic and only keep what wins. A losing test still tells you something a redesign never would.
Results that compound
Each experiment builds on the last. A programme that lifts conversion a few percent a month widens the gap on competitors who are still guessing, and it keeps widening.
Research, design and build in one team
The people who find the problem design the fix and build it. No handover between a research agency, a design studio and a developer, and no waiting weeks for a variant to be coded.
Our conversion rate optimisation services
From a one-off audit to an ongoing programme of research, testing and iteration. Every service below is delivered by the team that also designs and builds the changes.
A fixed-price review of your Shopify store: analytics, funnel drop-offs, heatmaps, session recordings and page performance, delivered as one prioritised report ranked by revenue impact and effort. The way most of our long-term partnerships start.
Research, experimentation, design and development from one team, working through a shared backlog month after month. You direct the priorities; we advise on where the effort will return the most. This is where the compounding happens.
We design, build, run and read every test: a hypothesis grounded in your data, a primary metric with guardrails, a minimum of two full business cycles, and a plain-English readback of what happened and what to do next. Client-side with Shoplift, ABConvert or Convert; server-side on Shopify Plus where checkout and cart changes need it.
Moderated and unmoderated usability tests, customer interviews, surveys and journey mapping. You see exactly where people hesitate, abandon or misunderstand, with video evidence and prioritised recommendations. The right starting point for stores without the traffic to test yet.
Cart abandonment is where most revenue leaks. We simplify form fields, strengthen trust signals, tune shipping thresholds and payment options, and on Shopify Plus redesign checkout itself with extensions.
Where purchase decisions happen. Galleries, product information, add-to-cart placement, cross-sells, filtering and search, and landing pages that match the ad that brought the visitor.
Different experiences for different visitors, by traffic source, device, location and behaviour, so returning customers, first-timers and paid traffic each see the version that converts for them.
A prioritised roadmap. We do not test at random. You get a backlog of experiments ranked by expected commercial impact, so the tests most likely to move revenue run first.
A clear problem statement. Before anyone opens a design tool, we define what the test is meant to solve and why. Every experiment starts with a hypothesis grounded in your data.
Control and variant, side by side. We design and build the variant and show you both versions before anything is released to customers.
Guardrails on every test. A primary metric, supporting metrics and guardrails, so a gain in one place does not hide a loss somewhere else.
Tests that run long enough. We monitor each live test for anomalies and let it run for at least two full business cycles. We never call a test early.
A readback you can act on. When a test finishes you get a plain-English summary of what was tested, what happened, the commercial impact and the recommended next step. Losing tests are written up with the same care as winners.
We moved Lioness to a lightweight Shopify 2.0 theme with a full look and feel refresh, custom mega navigation, upgraded collection and product pages, and a redesigned cart drawer. Speed and conversion came first, with no regression of existing features, and a roadmap set for cross-sell, loyalty and international rollout.
In the first six weeks after launch, compared with the same period a year earlier:
The audit is a fixed-price review of your store that hands back one prioritised report. Most of our CRO partnerships start there, because it shows what is worth fixing before anyone commits to a programme.
Ready to find out where your store is losing sales?
Start with the audit. You get one prioritised report, and a clear view of whether an ongoing partnership is worth it. Or book a call and we will tell you which makes sense for your store.
