SPREE is a British Shopify optimisation studio for established eCommerce brands. We fix what your customers actually feel — real speed, real conversion, real craft — not just the numbers on a dashboard.
No rebrands for the sake of it. No vanity metrics. Just the handful of things that reliably move revenue for an established Shopify store — done properly.
We fix the speed your shoppers actually feel — on real phones, on real connections — then mop up your PageSpeed and Core Web Vitals scores. The single biggest conversion lever on Shopify.
Explore Physical SpeedClinical-grade UX for beauty and lifestyle brands. We diagnose the signs of digital ageing — high bounce, abandoned carts, sluggish pages — and restore your store's elasticity without a full rebuild.
Explore Digital FaceliftTheme customisation, landing pages, checkout refinements and bug fixing — focused on the collection, product and cart pages where conversion is won or lost.

Try AssetScopeMost agencies are chasing the wrong numbers. A PageSpeed score. A Lighthouse report. A redesign that photographs well. And then nothing changes in the revenue line.
Everything SPREE does starts from that question. We measure the store the way a real shopper experiences it — on their phone, on their connection, across the whole journey from collection to checkout — and we fix the things that genuinely stand between them and the buy button.
Then we tidy up the scores. Because once the underlying store is better, the numbers follow — and this time they mean something.
A low score often points to real problems — but fixing the score without fixing the underlying experience is like painting over damp. The number goes up; the problem stays.
We've seen stores with a PageSpeed score of 85 that feel painfully slow to browse. We've also seen stores score 40 and convert brilliantly — because the things customers actually wait for load fast.
A synthetic lab test of a single page, on a simulated mid-range device, with a throttled 4G connection — run once, in isolation, with no real user interaction.
A real journey across multiple pages — collection, product, cart, checkout — on their actual device, on their actual connection, with their impatience as the clock.
Whether it's a speed project, a facelift or an ongoing retainer, every engagement follows the same honest, no-nonsense structure. Nothing is changed until we understand what moves the needle.
We analyse your store through the lens of a real shopper — load times, interaction delays, layout shifts, UX friction and app bloat on the pages that matter most.
We resolve the issues that cost you sales: render-blocking scripts, unoptimised images, bloated third-party apps, clumsy journeys and theme-level bugs.
Once the store is genuinely better, we turn to PageSpeed, Core Web Vitals and on-page SEO. Now the score improvements are authentic, not cosmetic.
We verify every change with field data — Chrome UX Report and your own analytics — then keep the store that way with ongoing monitoring and care.
A small, senior team that works exclusively on Shopify. Less noise, more craft — and results you can see in your revenue, not just a report.
We work exclusively in the Shopify ecosystem. We know exactly which app combinations kill speed, which theme patterns create bottlenecks, and how to fix them cleanly.
We optimise what customers feel, not just what bots measure. Real speed improvements that show up in your conversion rate, not just a dashboard.
Speed and polish without sacrifice. We never strip out features to chase a score. Every change is tested across desktop and mobile before it goes live.
We connect every project to business outcomes. You'll see before-and-after data on load times, Core Web Vitals and — most importantly — conversion rate.
You work directly with the people doing the work. No account managers, no hand-offs, no juniors learning on your store.
Most Shopify stores are still slow and clunky because most agencies focus on aesthetics, not infrastructure. Getting this right is a genuine advantage.
We're confident in our process because we've done it for dozens of established Shopify brands. Our free audit will show you exactly what's holding your store back — before you spend a penny.
Book Your Free AuditThe things Shopify merchants ask us most before we start working together.
We make established Shopify stores perform better. That means physical speed optimisation, UX and conversion work, theme customisation, bug fixing, and ongoing maintenance — all focused on the things that measurably increase revenue. We don't do full rebrands or build stores from scratch; we make the store you already have work harder.
Yes. Working exclusively in the Shopify ecosystem means we know the platform's quirks, the apps that cause trouble, and the theme patterns that create bottlenecks. That depth is what lets us fix things quickly and cleanly.
With a free audit. We'll look at your store's real-world speed, UX, apps and theme health, and give you a prioritised list of fixes ranked by impact on conversion. From there you can decide whether to tackle it yourself, hire us for a project, or put us on retainer.
Physical speed is the speed your actual customers perceive — how quickly images appear, how fast pages respond to taps, how smooth checkout feels. PageSpeed Insights is a synthetic lab test; useful, but not the same thing. We lead with physical speed because it's the single highest-leverage improvement available to almost any Shopify store.

No. We take a careful, tested approach to every change. Before going live, everything is verified for functionality across desktop and mobile. We never sacrifice features for speed points or aesthetics.
Most speed and conversion projects show meaningful improvements within 2–4 weeks. We start with a thorough audit, then work through fixes in order of impact. Larger or more complex stores may take longer, but you'll see incremental gains throughout.
Yes. Stores degrade naturally as new apps are added, themes update and traffic patterns change. Our retainer keeps your store fast, stable and tidy on an ongoing basis — with regular monitoring, app audits and proactive fixes before problems reach your customers.
Tell us about your store. We'll analyse how it really performs for your customers, identify the exact issues costing you conversions, and show you what fixing them is worth.
