Conversion Rate Optimisation

Find the leaks, fix them.

Shopify Experts, Shopify Plus Partner (opens in a new tab)

More traffic isn't always the answer. Our CRO service takes a data-first approach to understanding exactly where your Shopify brand is losing sales and fixes it with precision testing, UX improvements, and conversion-focused design. The result: more revenue from the visitors you already have.

Every change we recommend has already been tried on a checkout we pay for ourselves. We report the tests that lost alongside the ones that won, because knowing which idea was wrong is what stops you building it.

A/B testing

Conversion rate optimisation agency

How we run a CRO programme

Four steps against the traffic you already pay for. We find where the money leaks before proposing anything, because a test on a page almost nobody reaches teaches you very little and costs a month finding that out.

  1. Audit and Baseline

    We audit your brand and establish baseline conversion metrics across key pages and funnels so we know exactly what we are improving against.

  2. Hypothesis and Prioritisation

    Based on the audit findings, we build a prioritised list of hypotheses ranked by potential impact and ease of implementation.

  3. Test and Implement

    We run structured A/B tests on high-priority changes, implementing winners and iterating continuously based on real data.

  4. Report and Iterate

    Monthly reporting covers what was tested, what won, and what’s next, keeping you informed and in control of your brand’s performance at all times.

Shopify CRO agency

Why Shopify CRO pays for itself

You already paid for the traffic. Conversion rate optimisation gets more revenue from the visitors arriving today, which costs less than buying more of them. We find where your funnel leaks, test the fix, and keep what wins.

We test on Powerlete and Fittr Nutrition before we test on you. Running our own stores tells us which changes move a conversion rate and which ones read well in a case study while doing nothing.

Most people comparing one conversion rate optimisation agency against another are really asking two questions: whether the work is a project or a programme, and who builds the variants. A conversion rate optimisation consultant directing your own developers is often the cheaper answer, and an ecommerce cro agency earns its cost when nobody in-house has the time. We are a cro agency uk-side that also runs its own stores, which is the only reason our opinion on your checkout is worth more than a best-practice list.

CRO suits stores with steady traffic and a conversion rate that has stopped climbing. If your traffic is thin, put the money into getting more of it first: optimising a trickle returns less than filling the top of the funnel.

Search website optimisation services, website optimization services or a website optimisation company and Shopify is not even in the query, though the CRO work is identical whichever platform sits underneath it. Web optimisation companies, web optimisation services and conversion optimization services or a conversion optimization company describe the same slice of work again: somebody finding where a website loses people and fixing it, checkout or no checkout.

A shopify cro agency has one advantage over a platform-agnostic one and it is narrow: knowing which parts of the checkout you are allowed to change. On Plus you can rebuild it; below Plus you cannot, and half the ideas in a generic CRO audit are not implementable on your plan. Cro consulting services that hand you a list without checking which tier you are on waste the first month proving that.

  • Data-led decisions, not guesswork: every change is backed by evidence
  • Increase revenue without increasing your ad spend
  • Ongoing testing and iteration, not a one-off fix
  • Built on real experience running and optimising our own Shopify brands

Conversion rate optimisation

What is conversion rate optimisation?

Conversion rate optimisation is the work of getting more of the visitors a store already has to buy. It finds where people leave, works out why, and tests a change against the page as it stands, so the store only keeps what the numbers support.

The rate on its own can mislead. A discount raises it and can still lose money, which is why average order value sits in the same programme and a test is read against revenue rather than clicks.

On Shopify there is one constraint worth knowing early. Below Plus the checkout is fixed, so the work goes into everything leading up to it. On Plus, checkout extensibility opens the checkout itself to testing.

Conversion rate optimisation services

What our conversion rate optimisation service includes

Three jobs, in order: find where the store loses people, prove the fix before it ships, and put the effort where the revenue actually sits.

Finding the leak

Conversion Audit

We start with a deep audit of your brand’s conversion funnel, identifying the specific pages, elements, and flows where visitors are dropping off and why.

Heatmap and Session Analysis

Using tools like Hotjar and Microsoft Clarity, we analyse how real users interact with your Shopify store, uncovering friction points that analytics alone won’t show.

Proving the fix

A/B and Multivariate Testing

We design, run, and analyse structured tests across your key pages so every change is validated before it goes live permanently.

Where the money is

Checkout Optimisation

The checkout is where you lose the most revenue. We audit and optimise every step of the checkout flow to reduce abandonment and increase completed purchases.

Product and Collection Page Optimisation

Your PDPs and PLPs do the heavy lifting. We optimise copy, imagery, layout, and calls to action to maximise add-to-cart rates and purchase intent.

AOV Growth Strategies

More revenue per order means more profit without more traffic. We implement upsell, cross sell, and bundle strategies directly into your experience.

01

Find

Before anything is tested, the evidence: where people leave, what they were looking at, and what it costs.

Ecommerce CRO agency

Luxury fashion, and tracking built to find the real wins

Bessette sells new, curated luxury fashion across clothing, shoes, bags and jewellery from a long list of names. Two founders run it, and we work closely with both.

We run conversion rate optimisation across the site alongside merchandising and paid media on Meta and Google, on a tracking setup built to find the changes with real impact. Their figures are theirs to publish, so none appear here.

A luxury storefront that is tested, not only styled

Nour Hammour makes leather and tailored outerwear in Paris. At that price point a visitor judges the brand on the site long before the coat arrives.

We built the store, run conversion testing on it and look after it day to day on a retainer, so whatever a test proves is shipped by the people who know how the store was made.

Our CRO tech stack

The stack we run CRO on

Three of these watch how people actually behave on a page and the rest tell you what it was worth. We run all of them on our own checkouts, where a bad call costs us the order rather than a slide.

Test

A change earns its place by beating the page it replaces, on real traffic, to significance.

WUKA

Store build, then conversion testing

Shopify CRO

Pages that had to explain the product, kept only once they won

WUKA makes leak-proof reusable period underwear, a category that barely existed a decade ago. The store had to answer how it works, how it fits and how many pairs someone needs before asking anyone to buy.

We built the store, then ran conversion testing on it, so the pages doing the explaining were the ones that had earned their place in a test.

Shopify conversion rate optimisation

Every test runs on our own checkout first

Powerlete is our own sportswear brand, built and scaled from launch. Every playbook is tested there before it reaches a client, so when a checkout change costs money, it costs ours.

It is also where we learn which changes move a conversion rate and which ones read well in a case study while doing nothing.

CRO agency or consultant

Who should build your tests

The real difference between an agency, a consultant and an in-house team is who builds the variants. Everything else follows from that.

Compound

The rate is one number. What each order is worth is the other, and it moves the revenue just as far.

Ecommerce conversion optimisation

Average order value up 20% on our own store

Fittr Nutrition is our supplements brand, best known for its creatine gummies, and the cleaner of our two builds. The team that builds for clients runs it end to end.

Conversion work on this store lifted average order value by 20%, measured on 10 September 2026. It is one project’s dated result rather than a live number, and we can publish it because the store is ours.

How we work with you

CRO programme

Audit, hypotheses, tests and a monthly report on what won, what lost and what runs next. Ongoing, because a single project gets one or two answers and a list of things nobody reached.

Monthly

Conversion audit

The first step on its own: a baseline across your key pages and a prioritised list of what to fix, ranked by likely impact and effort. You keep the list whoever builds it.

Project

Consultant-led testing

We decide what to test and read the results, and your developers build the variants. The cheaper answer when you have the capacity in-house.

Advisory

Is this the right thing to buy from us?

Worth a conversation

  • Steady traffic, and a conversion rate that has stopped climbing
  • You pay for traffic and want more back from it
  • Someone, yours or ours, can ship what the testing finds
  • You want the losing tests reported as well as the winners

Probably not this, yet

  • Traffic is thin, and a test would run for months without an answer
  • You are pre-launch, with nothing to measure yet
  • You want a redesign first and evidence afterwards
  • You want a best-practice list rather than tests
More traffic first, instead

Partners

Tools we have already run on our own stores.

The apps around a Shopify store decide as much as the theme does, and choosing between thousands of them is most of the work. We are a Shopify Plus Partner and we integrate the tools that sit around the platform. Every one of them runs on our own two stores before it reaches a client, so the recommendation you get comes from having paid for the thing and lived with it. When a brand already runs a stack that works, we integrate with it rather than rebuilding it to suit us.

How we use them

Straight answers

How much traffic do we need before CRO is worth it?

Enough that a test reaches significance in a sensible timeframe. On lower order volumes a split test can run for months without a clear answer, so we lean on research and known fixes until the volume supports testing.

What do you change first?

Whatever the evidence points at. Most of the wins sit in the product page, the cart and the checkout, alongside site speed and how clearly you state delivery and returns.

How long until we see results from CRO?

A test has to run to significance before it means anything, so expect weeks rather than days. We report the tests that lost as well as the ones that won.

Do you use a testing tool?

Yes, matched to your traffic and budget. We will not load a heavy testing script onto a store where it costs more in speed than it returns in insight.

Can you raise conversion without redesigning the site?

Usually. Most early wins come from copy, clarity and speed rather than layout. A redesign is the expensive option and we reach for it last.

Do you optimise the Shopify Plus checkout?

Yes. Checkout extensibility on Plus gives real room to test, and we use it. On standard Shopify the checkout is fixed, so we work on everything leading into it.

What counts as a good Shopify conversion rate?

It varies by category and price point, so comparing yourself to a blended industry average tells you little. The number worth tracking is your own, month on month, against the changes you shipped.

Is CRO a project or an ongoing service?

Ongoing, and the reason is arithmetic rather than preference. A test needs enough traffic to reach significance, so a single project delivers one or two answers and a list of things nobody got to. Running it as a programme means the losing tests still pay, because knowing which idea was wrong is what stops you building it.

Do we need an agency, or would a consultant do?

A consultant is the right answer more often than agencies admit. If you have developers who can ship what the testing finds, someone senior telling you what to test is enough. An agency earns its cost when nobody in-house has the time to build the variants, because a recommendation nobody implements is worth nothing.

What does CRO cost?

It scales with how much building the tests require rather than with your revenue. A programme on a store with steady traffic and a developer available is a fraction of one where every variant needs building from scratch. We would rather scope it against what your site actually needs changing than quote a retainer and work backwards.

Do you do CRO on sites that are not ecommerce?

Yes, and it is a different job. Without a checkout the conversion is an enquiry, so the thing being tested is the form, the proof around it and how quickly somebody gets a reply. The method carries across, which is more than we would claim for most of what we do: we test on our own stores first either way.

Is ecommerce CRO different from Shopify-specific work?

Not really. Ecommerce cro is the general term, and shopify conversion rate optimisation, or shopify conversion optimization if you are searching the American spelling, is the same discipline scoped to one platform, which is what most of our work actually is.

Are you a CRO agency London brands can work with in person?

Yes, and it matters less than the search volume suggests. Cro agency london, cro agencies london, cro london and conversion rate optimisation london all describe a team you could meet, and we are happy to. Almost none of this work needs anybody in a room: the analytics, the session recordings and the tests all happen wherever the people doing them are. Searching conversion rate optimisation agency near me is convenient, not a quality signal: proximity tells you nothing about whether they can change your store.

How do CRO agencies differ from a CRO consultant or a CRO service?

By who does the building. Cro agencies and a cro marketing agency generally include the people who implement the change; a cro consultant usually directs your developers instead, which is cheaper and works well if you have the capacity. A cro service sold as a monthly retainer can be either, so ask which. Conversion rate experts who only ever hand over a document are the version that most often fails to pay for itself.

What does an ecommerce conversion rate optimisation agency actually change?

On most stores, information rather than aesthetics. An ecommerce conversion optimisation agency worth its fee spends its first weeks finding where people leave and why, not redesigning. Ecommerce conversion optimization work is mostly removing surprises: a delivery cost that appears late, an objection the product page never answers, a step in the checkout that exists for internal reasons.

Do you offer Shopify CRO services specifically?

That is most of what we do. Shopify cro services differ from the general kind in the practicalities rather than the method: the checkout is largely locked on standard plans, apps interfere with tests, and theme changes range from trivial to development work with no obvious pattern. Conversion rate optimization experts without platform experience will get the analysis right and the implementation slow.

How do we tell good CRO experts from the rest?

Ask what they last shipped and what happened, including a test that failed. Conversion rate optimisation experts who cannot name a losing test either have not run many or are not counting them, and a practice that only reports wins is not measuring properly. Ask too whether they will tell you when your traffic is too low to test, because the honest answer for a lot of stores is that it is.

Does conversion rate optimisation work for B2B and quote-based sites?

Yes, though b2b conversion rate optimisation and b2b conversion rate optimization look different from the ecommerce version: there is usually no checkout to fix, a form, a quote request or a call booking instead. The method is the same, finding where people give up and removing the reason, but what counts as a conversion has to be defined first. We run the same discipline for wholesale and trade buyers on our work with B2B and trade brands.

Tell us where the store loses people

Send the store and roughly how much traffic it gets. We reply personally, and if the honest answer is that there is not yet enough traffic to test, that is the reply you get.
