Measured across the 10 most recent DTC brands in 2026
Eleven is a design-led Shopify CRO agency in London and Brighton. CRO Growth is our monthly conversion rate optimisation retainer for established DTC brands. It starts with an audit, then runs a repeating cycle of research, A/B testing and in-house design and development, with Subscription Intelligence™ for brands on Recharge, Skio and Loop.
Who our Shopify CRO retainers are for
You've launched, traffic is steady, and you're ready for the store to work harder for it.
Around 20,000 monthly sessions lets a test reach a clear answer in weeks. Below that, we focus on bigger, research-led changes instead of tests that never conclude.
The best results build on each other over 6–9 months, so we plan as a partner, not a one-off fix.
Shopify CRO services, in one retainer
We find where shoppers hesitate and fix it, across product pages, collections, cart and checkout. Every change is tied to a number we can measure.
Structured tests on layouts, messaging, offers and flows, run with Shoplift and Shopify SimGym. Not every test wins, but every test teaches us something, and that goes straight into the next one.
Sometimes the answer is a new feature, so we design and build it: bundle builders, subscription builders, gift-with-purchase, first-time customer flows. No handover, no waiting on another agency.
Subscription and AOV optimisation built on your Recharge, Skio or Loop data. We grow subscribers, order value and LTV, not just conversion rate.
Clearer homepages, PDPs and paid-media landing pages, with stronger trust signals and better mobile UX, without losing what makes your brand yours.
Speed, app hygiene, QA and fixes, handled every month, so the store stays quick and stable while it grows.
How our Shopify CRO process works
Every change starts as a hypothesis and ends as a result we can show you. No guesswork, and no redesigns for the sake of it.
00 Audit
We start with a UX/CRO, Subscription Intelligence™ and technical audit. It sets the baseline everything else is measured against.
01 Research
Analytics, heatmaps, behavioural analysis, session recordings and subscription data show where shoppers drop off, and why.
02 Prioritise
Ideas become hypotheses, scored on impact, confidence and effort. You see the roadmap and agree it with us.
03 Design & build
Our designers and Shopify developers build the variants, or the new feature, in house.
04 Test
We run tests until the result is clear. If traffic is too low for a clean test, we'll tell you and use a better method.
05 Ship & learn
Winners go live. What we learn shapes the next sprint, so the store gets smarter every month.
What our clients say
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.
Shopify CRO agency FAQs
A Shopify CRO agency helps more of your visitors become customers, and helps them spend more. At Eleven, that means research, A/B testing, UX design and Shopify development in one team, so ideas get tested and the winners get built, not left in a slide deck.
Every CRO Growth retainer is shaped around your store, so there's no fixed price. It depends on how many tests and how much design and development you need each month. We'll recommend a level after the audit, so you're not paying for capacity you can't use.
Most brands see their first tested wins within weeks. The first month covers research and setup, and tests need time to reach significance. The bigger gains build over months, as each sprint builds on the last.
Around 20,000 monthly sessions lets most tests reach a clear result in a few weeks. With less traffic, we focus on larger, research-backed changes and measure them carefully, rather than running tests that never conclude.
Usually, yes. Most CRO Growth retainers begin with an Eleven audit, so the roadmap is grounded in your data rather than guesswork.
All three. One team covers CRO strategy, UX design and Shopify development, so there's no handover between agencies, and winning ideas ship faster.
Yes, it's what we're known for. Subscription Intelligence™ uses your Recharge, Skio or Loop data to improve subscriber conversion, order value and retention, alongside first-order conversion rate.
Yes. We're a Shopify Plus Partner, and CRO Growth works on both Shopify and Shopify Plus stores.
