More Sales From the Traffic You Already Have

More Sales From the Traffic You Already Have

Most Shopify stores spend heavily to win visitors, then lose most of them before checkout. A small lift in conversion rate multiplies every pound you spend on ads, SEO and email.

We are a UK Shopify agency based in Brighton and a Shopify Select partner. Our conversion rate optimisation work brings research, design and development into one team, so the changes we recommend are the changes we build, test and measure.

Want the benchmarks first? Our guide to Shopify conversion rates shows what good looks like.

Why Conversion Rate Optimisation Comes First

Across 265 Shopify stores we have audited, the median conversion rate is 1.7%. Lifting it to 2.2% brings about 29% more orders from the same visitors, without spending another pound on ads. Between 2024 and 2026, Mama Bamboo's conversion rate rose from 2% to 5%.

That makes CRO the multiplier for everything else. Every improvement lowers your cost per sale on Google, Meta and TikTok, and makes your email and SEO traffic earn more.

It works best alongside the rest of your marketing, which is why our ecommerce growth agency service puts conversion first.

How Our Shopify CRO Service Works

Every project starts with a CRO audit: your analytics, behaviour data and a page by page review of the journey from landing page to checkout, on mobile and desktop.

We turn what we find into a list of changes ranked by likely impact and effort, then design, build and measure them in order, starting with the problems that cost the most sales.

Retainers start from £650 a month plus VAT and are billed one month in arrears, with no long contract. Our prices are published on our Shopify packages page.

Product Pages That Sell

The product page is where most buying decisions are made. Shoppers want clear images, honest detail, reviews, delivery costs and returns before they commit.

Where a product page was badly designed, our redesigns typically lift its conversion rate by about two percentage points. We rebuild layouts, copy and calls to action around the questions your customers actually ask.

Our guide to product page design shows what we change first.

Basket and Checkout

Unexpected costs, forced account creation and slow payment steps are among the most common reasons shoppers abandon a basket. We show delivery costs early, remove unnecessary steps and make every payment option easy to find.

Shopify's checkout is already strong, and Shopify reports that Shop Pay can lift conversion by up to 50% compared with guest checkout. We make sure Shop Pay and other express payments are switched on and visible, and fix apps or customisations that slow the journey down.

Our abandoned cart statistics show where shoppers drop out and why.

Speed and Mobile Experience

Speed has a direct effect on sales. In Deloitte's Milliseconds Make Millions study, a 0.1 second improvement in mobile site speed lifted retail conversion rates by 8.4%.

Of the 265 stores we audited, 196 were still on legacy themes, and moving stores onto Online Store 2.0 themes has produced an average gain of 23 points in mobile PageSpeed. We also remove heavy apps and scripts, and design every page for phones first.

Our guides to your Shopify speed score and mobile first design go further.

Testing Changes You Can Trust

Not every change works, so we measure each one. Where a store has enough traffic, we run A/B tests that split visitors between the old and new version until the result is clear. Every change is also checked across browsers and devices with LambdaTest before it goes live.

Smaller stores rarely have the traffic for reliable A/B tests, so we compare results against a clear baseline instead and allow for seasonal effects. Either way, you see what changed, by how much and what we recommend next.

Our guide to increasing Shopify conversions covers the quick wins we test first.

Research That Explains Why Visitors Leave

Numbers show where visitors leave; research shows why. We combine analytics with heatmaps and session recordings from Microsoft Clarity, on site surveys and customer reviews to find the doubts that stop people buying.

We also check the journey for accessibility, because a store that is hard to use with a keyboard or screen reader loses sales as well as risking complaints. Our European Accessibility Act guide explains the rules for stores selling to the EU.

Tracking has to be right before any result can be trusted, so we check that every Shopify order reaches GA4 once, with the right value.

Frequently Asked Questions

What does a CRO agency do?

A conversion rate optimisation agency finds out why visitors leave without buying, then designs, builds and tests changes that turn more of them into customers. The aim is more revenue from the traffic you already have, not just more traffic.

What is a good conversion rate for a Shopify store?

Across 265 Shopify stores we have audited, the median conversion rate is 1.7%, but the right target depends on your sector, prices and traffic sources. Our guide to Shopify conversion rates sets out benchmarks and fixes.

How much does CRO cost?

Our CRO retainers start from £650 a month plus VAT, billed one month in arrears, with no long contract. The right level depends on how much design and development each round of changes needs. Our guide to Shopify agency pricing compares the main pricing models.

How long does CRO take to show results?

Quick fixes, such as clearer delivery costs or a faster product page, can show results within weeks. A/B tests need enough visitors to give a reliable answer, so larger tests usually run for several weeks.

Do we need a lot of traffic for CRO?

No. A/B tests need enough visitors to be reliable, but smaller stores still benefit from research, fixes and before and after measurement. We tell you which approach your traffic supports.

Will CRO changes affect our SEO?

Done well, they help it: faster pages, clearer content and better mobile layouts are good for search too. We keep your page titles, content and structured data intact when we change layouts, and our Shopify SEO agency team checks anything that touches rankings.

Can you build the changes as well as recommend them?

Yes. Unlike CRO consultancies that hand over a report, our own designers and developers build every change in your Shopify theme, covered by our 3 month guarantee on development work.
