CRO Growth: Optimisation for high-performing Shopify stores requiring ongoing success.

Designed for brands that want sustained performance improvements — driven by design & data.

CRO Growth is Eleven’s ongoing success programme designed for brands that want sustained performance improvements, as well as on going maintenance. Combining behavioural data, UX design, Subscription Intelligence™, and technical optimisation plus creative experimentation, we uncover friction, validate ideas, and systematically improve your customer journey. From landing pages to technical enhancements, every change is strategic, measurable, and driven by real user behaviour.

The result? Higher conversion, stronger subscription uptake, improved AOV, and a store that gets smarter every sprint.

Our E-commerce and shopify services for your DTC Brand

Conversion rate optimisation

Ongoing analysis and optimisation of your full conversion funnel to reduce friction and increase revenue. We identify behavioural drop-offs, prioritise high-impact improvements, and continuously refine UX, messaging, and flows to drive measurable gains across conversion, AOV, and retention.

UX & landing page optimisation

Design and optimisation of high-performing pages that guide users with clarity and confidence. From homepages and PDPs to paid media landing pages, we improve hierarchy, storytelling, trust signals, and mobile UX to turn traffic into customers.

Custom functions & features

Purpose-built, bespoke Shopify enhancements designed to support growth, not complexity. We design and develop custom sections, flows, and features that improve usability, merchandising, subscriptions, and performance, while keeping your store fast, scalable, and easy to evolve.

A/B testing & experimentation

Structured testing to validate what actually drives performance. We plan, design, and implement A/B tests across layouts, messaging, offers, and flows, using real data to prove impact, scale winning ideas, and inform future optimisation decisions. From Shopify SimGym to Shoplift.

Monthly maintenance & enhancements

Proactive Shopify maintenance and continuous improvement delivered monthly. From performance updates and QA to UX refinements, app optimisation, and technical hygiene, we keep your store stable, secure, and consistently improving as your business grows.

Eleven is our one stop shop for everything related to branding, from concept to execution. They built our website handling UI/UX and development. The site has a complicated functionality; our clients can custom-build their own sofa and the team at Eleven helped us determine how it worked for our stock and site.

Eleven are design-orientated, rapid movers, and detail-focused without cutting corners, which impressed us. Eleven created a cohesive brand image and improved the site's UX, which resulted in increased conversions. The team was consistently available, organised, and flexible, with straightforward communication. They were knowledgeable, and their openness to feedback and quick response stood out.

Eleven increased sales on our most popular products, as well as funnelling customers to choose our most desired products. They made bundling of products really easy, and increased AOV by 9% in 2 weeks! They managed a lot of different projects concurrently and kept track of them all. All projects have been delivered beyond our original expectations. I've found working with Eleven to be brilliant.

I was impressed with their attention to detail and research. It was clear that Eleven had a great understanding of not only the e-commerce space, but our category. Their research prior to kicking-off the work was on point and gave faith in the project from the get-go. When we did dive into design and build, there was clear attention to detail and the level of output was high.

The biggest thing I would say about working at Eleven, beyond the great design & UX, is the culture you have built. You have a team of experts who are also leaders in their own right, and it’s been a pleasure working with them. Big shout-out to Nicola, Ben & the team.

Who is CRO Growth best suited for?

CRO Growth is ideal for established Shopify brands and fast-scaling DTC teams who want continuous improvement post-launch. If your store is live, generating traffic, and ready to optimise conversion, retention, and AOV, this is for you.

Do we need an Audit first?

Yes! Most CRO Growth retainers begin with an Eleven audit. This ensures we prioritise correctly, avoid guesswork, and build a roadmap grounded in real data and opportunity.

Is this design, development, or strategy?

All three. CRO Growth blends UX design, Shopify development, and strategic CRO thinking into one integrated retainer, removing silos and speeding up impact.

Can CRO Growth include subscriptions and retention?

Absolutely. Subscription optimisation and retention strategy are core to CRO Growth and a key differentiator of Eleven’s approach.
