TL;DR
Conversion Rate Optimisation (CRO) help you turn more of your existing visitors into customers. It helps in lifting revenue, lowering acquisition costs, improving UX, and building long-term loyalty.
In short: CRO helps your Shopify store work smarter, not harder.
What is Conversion Rate Optimisation (CRO)?
CRO, or Conversion Rate Optimisation, is the process of improving or optimising your website so a higher percentage of visitors complete a desired action, for example, purchase, email sign‑up, add to cart, or subscription. For the purposes of this blog, we refer to the ‘conversions’ as completing a purchase on your website.
While Conversion Rate is one of the metrics tracked during CRO, it is only one of the metrics you are looking to optimise when we talk about CRO. When conducting CRO on your website, you should also focus on these metrics:
- Add to Cart
- Reached Checkout
- Average Order Values
- Revenue Per Visitor
- Repeat Purchase Rate
- Bounce Rates
Instead of chasing clicks, CRO focuses on what happens after the click. Using behavioural data, testing, and design refinements, it removes friction from the path to purchase and aligns the experience to user intent.
For Shopify brands, that means unlocking more revenue from your current traffic while creating a seamless journey from homepage to checkout.

Why is Conversion Rate Optimisation important?
Small uplifts compound. If you get 50,000 monthly visitors, moving conversion rate from 2% to 3% adds 500 extra orders with zero extra ad spend.
For example, in one of our A/B Tests to expose the Search on Mobile, this particular brand saw an estimated uplift of +682 additional monthly orders. Without spending any more on paid advertising.

CRO makes your marketing more efficient. When each step is designed to guide visitors towards a purchase, you reduce wasted budget, improve Return on Investment (ROI), and scale sustainable.

Key Benefits of Conversion Rate Optimisation (CRO)
Increased Revenue and ROI
CRO helps you generate more sales from the same traffic. By testing layouts, copy, CTAs, and UX patterns, you uncover what motivates users to convert, and you can reinvest the gains back into growth.
In this particular A/B Test for an apparel brand, we tested enabling a Sticky Add to Cart on the Product Details Page (PDP), to encourage more users to convert. Our test resulted in an increase of +27% in Revenue per Visitor. By making the 'Add to Cart' button persist on scroll, we managed to increase Revenue per Visitor without incurring additional acquisition costs.

Deeper Customer Insights
Tools like GA4, heatmaps, and on‑site surveys reveal where users hesitate and why. These insights inform marketing, UX and product decisions across the business, not just your website.
Lower Customer Acquisition Costs (CAC)
Traffic is expensive. Improve how effectively you convert what you already have, and your CPA drops, making every channel more profitable.
Enhanced User Experience (UX)
Reducing friction (page speed, search & navigation, decision clarity, and checkout steps) makes it easier to buy. The result is lower bounce rates, higher conversion rates, and greater trust.
In this example, a product-focused review placed higher on the PDP increase Conversion rate by +19.14% and Revenue per Visitor by +10.77%. It also increased product exploration (+27.27% products per visitor).
Before vs After adding a product-specific review
This shows how enhancing the UX with decision clarity on product pages can increase your conversion rate metrics without having to spend more on traffic.
Improved Brand Credibility and Trust
A fast, polished store with social proof and clear policies signals reliability. Trust elements, such as reviews, testimonials, and security badges, reassure shoppers at the point of decision.
In this A/B Test, we placed three trust cues under the Add to Cart, resulting in:
- +13.5% Conversion Rate
- 39.8% Revenue per Visitor
- 34.5% Add to Cart rate

Leverage Existing Traffic
Rather than constantly finding new audiences, CRO converts more of your current visitors, thereby compounding performance over time and turning browsers in buys.
In this example, we tested replacing generic "You may also like" text with on-brand, benefit-led copy, leading to increased product additions from the Rebuy Smart Cart by +83% and improving Conversion Rate by +5%.

CRO Audit
We’ll begin with an in-depth CRO Insights Roadmap, where we will analyse your data, including Shopify analytics, GA4, UX competitor benchmarking, heatmaps and session recordings, to uncover 40+ recommendations through quick wins, A/B tests and longer-term strategies.
Your roadmap of recommendations will be prioritised using our PECTI Framework (scored according to Proof, Ease of achievement, Cost, Time to implement, and Impact potential) to ensure that you address the highest priorities first.
Time required: 3-5 weeks
CRO Implementation
We then move into CRO Implementation, where we’ll agree on the priorities for the month ahead. You review every step of the way from Strategy → Design → Development → A/B Testing. We report on the tests, providing additional insights and recommendations, and, with your approval, we will push the winning test live.
After three months of implementation, we’ll begin reporting on your onsite metrics, and uncovering new opportunities to add to your PECTI. We’ll reprioritise your PECTI each month from this point to ensure that we always address the highest priorities first. We’ll also begin reporting on quarterly KPI metrics so you can see the results we achieve together.
