EXPERIMENTATION

Stop losing customers you've already earned

Experimentation identifies the barriers and motivations that stop people completing the actions that matter on your site. Rather than redesigning based on opinion, we test specific, evidenced-based changes and only roll out what's proven to work.

Behavioural Data

We understand your customers by combining web analytics and digital experience data to uncover where they hesitate.

User Research

Direct research reveals the real reasons customers drop off. No guessing what might look better.

Evidence-Led Testing

Every test we run is based on real insight, so only proven improvements make it to your live site.

Our CRO process

Find. Prioritise. Fix. Prove. Scale

Find

We connect evidence from analytics, research, user behaviour and experiment history to see where the real opportunity sits.

Prioritise

We rank opportunities by customer impact, commercial value, confidence and implementation effort, so the roadmap tackles what matters most first.

Fix

We design and build the change, whether that's a new page layout, a simplified checkout step or a rewritten piece of content.

Prove

We test using client-side or server-side experimentation to confirm the change actually improves the desired metrics before it’s rolled out.

Scale

We roll out what works, and feed the result back into the evidence base so every new test starts from a stronger position than the last.

CRO Enablement

Ready to go in-house?

Full service CRO is REO leading delivery for you. CRO Enablement is REO training, coaching and setting up your internal team so testing becomes something you run day to day, not something you outsource indefinitely.

If you're building toward an in-house experimentation capability, that's a different service with a different roadmap, playbooks, tooling support and governance, not more testing volume.

“You’ve done an incredible job. There is no way we would have gone through 19 tests in that period without you. You’ve done a great job of driving us. We simply would not have achieved this without you.”

“By combining insight and experimentation, REO helped us simplify complex choices and unlock meaningful gains in mobile conversion.”

“By working with REO, we were able to better understand our users and optimise their customer journey, resulting in a significant uplift across all KPIs.”

“Partnering with REO helped us re-imagine what a great digital experience means for our customers. Our My Account area is now more intuitive and self-serve, and our teams are working more collaboratively than ever.”

“Missoma worked with REO to refine how customers browse, evaluate and commit to purchasing jewellery on Shopify, with a specific focus on mobile-led journeys where hesitation and uncertainty were most pronounced. Rather than applying broad changes across the site, the programme focused on identifying the exact moments where users lost confidence and validating whether small experience adjustments could help them move forward with intent.”

“REO have been great to collaborate with, bringing new ideas, structuring and building tests in AB Tasty that we did not have the internal resources to deliver. They feel like a genuine extension of the Accu team and a valuable partner to learn from and work with.”

“Victoria Beckham partnered with REO to apply Shopify Experience Optimisation (SXO) across its ecommerce journey, introducing a disciplined experimentation programme designed to protect brand integrity while improving commercial performance. Rather than assuming that increased interaction or feature richness would drive results, SXO was used to identify which experience elements genuinely support purchase intent within a high-consideration, luxury context and which actively undermine it.”

“Focused on improving product discovery, trust and decision making within a Shopify environment, Bradshaw Taylor partnered with REO to deliver a structured experimentation programme across PLPs, PDPs and sitewide messaging. Through rapid testing and continuous iteration, the brand achieved double-digit conversion uplifts across key journeys, while validating which Shopify native components genuinely influence their customer behaviour.”

“REO Digital supported us in delivering a stable, secure, and modernised brochure site that brings our Figma designs to life. Their collaborative approach, CI/CD workflow, and structured release support ensured smooth deployment across environments and aligned closely with our internal DevOps processes.”

Frequently asked questions

What is conversion rate optimisation?

CRO is the process of increasing how many visitors complete the actions that matter to your business, such as buying, enquiring or signing up. We use analytics, user research and A/B testing to find what's stopping people converting, then test changes to prove what works.

How do you decide what to test first?

We prioritise opportunities using evidence from analytics, research and your commercial goals, weighing potential impact against confidence and effort. That means your first tests focus on the pages and problems most likely to move revenue.

Do we need a certain amount of traffic to run A/B tests?

Tests need enough traffic and conversions to reach reliable results, so we'll check your volumes before recommending a programme. With lower traffic, we focus on research-led fixes and only test on your highest-traffic pages.

How long before we see results from CRO?

First tests usually launch within the first few weeks, and quick fixes from the initial audit can go live sooner. Gains build over the first few months as tests conclude and each result informs the next.

Which testing tools do you work with?

We work with the major client-side and server-side experimentation platforms, and can run your programme on the tool you already have. If you don't have one, we'll recommend the best fit for your traffic, tech stack and budget.
