Ecommerce Conversion Rate Optimisation
Ecommerce CRO is the discipline of finding the specific moments where buyers leave your store without buying and fixing them. It is not guesswork or best-practice checklists. It is research into your actual buyers, hypotheses grounded in that data, structured tests, and changes that stick. We run CRO programmes on stores across platforms, and we measure every change against the metric that matters: orders.

What it is
What is ecommerce CRO?
Ecommerce conversion rate optimisation is an ongoing programme of research, hypothesis, testing, and implementation aimed at increasing the percentage of visitors who complete a purchase. It works at the level of specific funnel stages: the product detail page, the add-to-cart interaction, the cart page, the checkout steps, and the mobile experience across all of them. Each stage has its own friction patterns, and the right fix for one store is often wrong for another, which is why research comes before any change.
CRO is distinct from store design and from a one-time audit. Store design is a structural project that sets the layout and visual system. An audit is a diagnostic snapshot. CRO is the ongoing work that runs after the store is live: measuring what is actually happening, forming specific hypotheses about why buyers are leaving at each stage, testing changes in a controlled way, and rolling out what works. It requires sufficient traffic to produce statistically meaningful test results, so it is best suited to stores already receiving a meaningful number of daily sessions [verify minimum traffic threshold].
What's included
What a CRO programme includes
Funnel and analytics auditGA4 funnel analysis, drop-off mapping, and session data review to find exactly where buyers are leaving and at what rate [verify tooling].
Qualitative researchHeatmaps, session recordings, and on-site surveys to understand why buyers leave, not just where [verify tooling].
Hypothesis backlogA prioritised backlog of conversion hypotheses ranked by expected impact and implementation effort.
A/B and multivariate testingStructured tests run to statistical significance on product pages, cart, and checkout before any change is made permanent [verify testing platform].
Checkout optimisationTargeted fixes to checkout flow, field count, trust signals, and payment options to reduce abandonment at the final step.
Mobile CROSeparate research and testing on mobile flows, where conversion rates are typically lower and friction patterns are different from desktop.
Monthly reportingA monthly report covering test results, conversion movement, the next hypothesis queue, and cumulative programme impact.
How we work
How we run a CRO programme
1CRO audit
We analyse your funnel in GA4, map drop-off rates at every stage, and identify the highest-impact areas to investigate first.
2Qualitative research
We run heatmaps, session recordings, and surveys to understand the reasons behind the drop-off data [verify tooling].
3Hypothesis backlog
We build a prioritised backlog of specific, testable hypotheses ranked by expected conversion impact and implementation cost.
4Test design and build
We design and build the test variant, set the statistical significance threshold, and confirm the test is tracking the right metric.
5Test, read, decide
We run each test to significance, read the result honestly, and roll out winners or learn from losses before moving to the next hypothesis.
6Report and iterate
We report results monthly, update the hypothesis backlog based on what we have learned, and continue the programme cycle.
Why it matters
What a CRO programme compounds into
Each incremental conversion improvement compounds: more orders from the same traffic, month after month.
More orders from existing traffic
A higher conversion rate means more revenue from the visitors already arriving, without increasing your ad spend or SEO investment.
Friction you can name and fix
Research-led CRO tells you specifically what is stopping buyers, not just that conversion is low, so every fix addresses a real and measurable problem.
A test record that compounds
Each test result, win or loss, adds to a body of knowledge about your buyers that makes every subsequent hypothesis sharper.
Who this is best for
The right fit
Best for live stores with meaningful traffic
Stores already receiving enough daily sessions to run statistically valid tests [verify minimum threshold], with a conversion rate that is measurably below their category benchmark, or with a specific funnel stage where drop-off is disproportionately high.
CRO needs traffic to work
A/B testing requires sufficient visitor volume to reach statistical significance. If your store is early-stage or low-traffic, a Store Audit or Store Design engagement will produce a faster return than a testing programme that cannot reach significance.
FAQs
Common questions about ecommerce CRO
How much traffic do we need to run CRO?
A/B testing requires enough sessions to reach statistical significance on the metric being tested, typically orders or add-to-cart rate. The exact minimum depends on your current conversion rate and the size of the improvement being tested. We assess traffic volume in the audit and tell you honestly whether testing is viable or whether a different engagement is the better use of budget [verify minimum traffic threshold used].
How is CRO different from a store redesign?
A store redesign is a one-time structural project that changes the layout, visual system, and template architecture. CRO is the ongoing programme that runs after the store is live: measuring real buyer behaviour, testing specific changes, and improving conversion incrementally. The two are complementary: a well-designed store is a better starting point for CRO, but CRO is not a substitute for a design that is fundamentally broken.
Do you work on our platform?
We run CRO programmes on Shopify, WooCommerce, and BigCommerce. The research and hypothesis process is the same on every platform. The test implementation varies by platform and by what your theme or front-end architecture allows [verify platforms and testing tools used].
What do you actually test?
We test changes to specific elements that the research identifies as friction: product page layout and trust signals, add-to-cart button placement and copy, cart page design and upsell presentation, checkout field count and progress indicators, and mobile-specific layouts. We do not run tests for the sake of running tests. Every test comes from a specific hypothesis grounded in the research data.
How long before we see a conversion improvement?
The first test results typically arrive within 4 to 8 weeks, depending on traffic volume and test duration required for significance [verify]. The compounding effect, where multiple successive improvements stack, becomes meaningful at 3 to 6 months into a programme. We report honestly on every test result, including losses, so you always know what the programme is producing.
Can you run CRO on just one part of the funnel, such as the checkout?
Yes. We can scope a programme to a specific funnel stage, such as checkout abandonment, if the research already points to that as the primary problem. A scoped programme is often the right starting point when a particular stage has a disproportionately high drop-off rate and the rest of the funnel is performing reasonably well.
