Structured Experimentation Across Your Entire Store, From Product Pages to Checkout

How We Optimise Shopify Stores for Conversion

Every engagement follows a structured, four-stage process. No guesswork, no vanity metrics. Each step is built around your commercial goals and grounded in real user data.

Most Shopify brands know their conversion rate should be higher. Few have the setup, traffic strategy, or technical resource to systematically improve it. That's where we come in. Through our SiteLab model, we give Shopify and Shopify Plus brands access to a dedicated CRO team that audits, plans, builds, tests, and reports on conversion improvements across your entire store.

Every optimisation is hypothesis-driven, statistically validated, and tied to commercial outcomes. We've run hundreds of experiments across product pages, checkout flows, navigation, homepage layouts, and more. We know what moves the needle on Shopify because we've tested it firsthand, across brands in fashion, beauty, lifestyle, homeware, and DTC.

“Working with Charle Agency was an absolute dream, we really felt they had the time for us and the whole project was seamless start to finish”.

01
Audit & Discovery

We start with a full-store CRO audit using heatmaps, session recordings, analytics data, and customer behaviour analysis. We map the entire user journey to identify where visitors drop off, where friction exists, and where the biggest revenue opportunities sit.

02
Hypothesise & Prioritise

Every optimisation begins with a clear hypothesis: what we're changing, why we believe it will improve conversion, and the metric we're measuring against. We build a CRO roadmap in collaboration with your team, prioritised by commercial impact and effort.

03
Test & Iterate

Our designers and developers create variants and deploy controlled A/B experiments using tools like Shoplift, with clean traffic splitting and proper event tracking. Tests go live without disrupting your store's performance or speed.

04
Scale & Compound

We monitor every test until it reaches statistical significance. Winning variants get implemented permanently and the learnings feed directly into the next round of optimisation, creating a compounding cycle of conversion growth.

The Tools and Methodology Behind Every Optimisation

We use Shoplift as our primary A/B testing platform for Shopify. It integrates natively with the Shopify theme architecture, which means we can test layout changes, content variations, and component-level updates without bolting on heavy third-party scripts that slow your store down. For behavioural insight, we pair that with Microsoft Clarity for session recordings and heatmaps, Google Analytics 4 for traffic and funnel analysis, and Triple Whale for attribution. Every test is run until we reach a confidence level of 95% or above. We don't call winners early and we don't cherry-pick metrics. The result is a clear, honest picture of what's working and a library of learnings that compounds over time.

CRO Works Best for Brands Ready to Scale With Data

Our CRO services are built for Shopify and Shopify Plus brands that have traffic but aren't converting at the level they should be. If you're generating 10,000+ monthly sessions and want to turn more of that traffic into revenue, structured CRO is the fastest route to sustainable growth. We work best with ecommerce teams who value data over opinion, who want a dedicated optimisation partner rather than a one-off audit, and who are ready to commit to continuous improvement. Whether you're a founder looking to scale, a marketing team trying to improve ROAS, or an ecommerce director building a performance culture, our SiteLab model gives you the team, tools, and process to make it happen.
