High traffic and flat sales usually isn't a marketing problem – it's a conversion problem. This guide breaks down what a good CRO agency London actually does, what to look for before you sign a contract, and how BSS Commerce's audit-to-retainer model turns the traffic you already have into more revenue.
Before comparing agencies, it helps to name the symptom. Most stores that come looking for a CRO agency London wide are stuck in one of these patterns.
Ad spend keeps climbing, sessions keep growing, but the conversion rate barely moves month over month.
Add-to-cart numbers look fine, yet a large share of shoppers abandon before payment is complete.
The team suspects something is broken – a page, a step, an element – but has no data to point at exactly where.
Discounts and page tweaks have been tested before without a structured process, so nothing compounds.
No generic checklists. Every engagement is built around your store, your data, and your customers.
Before touching any data, we align on your goals, your customers, and what "conversion" actually means for your business.
We analyse your funnel step by step – conversion rates, segment behaviour, heatmaps, and session recordings – to pinpoint exactly where shoppers leave and why.
We evaluate UX end to end, then cross-reference findings with data to prioritise the improvements that matter most.
One audit produces a complete action kit every stakeholder can use from day one.
Key findings and business impact in one concise report for decision-makers.
A phased action plan sequencing quick wins, structural fixes, and test candidates.
A full breakdown of funnel data, traffic segments, and shopper behaviour.
Page-by-page evaluation covering copy clarity, layout, trust signals, and checkout flow.
8–18 conversion fixes paired with visual mockups ready for dev handoff.
5–10 prioritised test hypotheses so your team knows what to test next.
Every recommendation is grounded in real-world CRO audit work across Shopify and Magento stores.
London and the wider UK have no shortage of agencies offering conversion work, from boutique specialists to full-funnel consultancies. We reviewed a wide set of them in our own roundup of the cro agency london and UK market – covering their services, pricing bands, and the industries they serve best. What most of them share is a focus on marketing-led testing rather than platform-native execution. BSS Commerce sits in a different lane: a Shopify Premier Partner and Adobe/Magento Bronze Solution Partner that pairs structured CRO research with hands-on Shopify and Magento development, so findings turn into shipped fixes rather than a slide deck.
A CRO agency analyses user behaviour across your site – funnels, heatmaps, session recordings, and UX – to find where shoppers drop off, then recommends and tests fixes to turn more visitors into customers.
BSS Commerce combines CRO research with in-house Shopify and Magento development, so audit findings are handed off as implementation-ready fixes rather than a report your team has to translate into code.
Typically 3–6 weeks depending on store complexity and size, with a confirmed timeline agreed before work begins.
You can implement the roadmap with your own team, or continue with BSS Commerce's CRO Retainer for ongoing structured A/B testing.
Pricing depends on store size and complexity. Contact us for a scoped proposal before anything begins.
