How much should a Shopify CRO audit cost in the UK?

A Shopify CRO audit can cost anything from a few hundred pounds for a focused expert review to several thousand pounds for a deeper evidence-led programme. The price alone tells you very little. What matters is what is being investigated, what evidence is used, how recommendations are prioritised and whether you can actually act on the output.

For a UK ecommerce business, the useful buying question is not “what is the normal CRO audit price?” It is: what level of diagnosis does my store need, and what should I expect to receive for that money?

What does a Shopify CRO audit actually cost in the UK?

There is no standard UK tariff for a conversion-rate optimisation audit. Public pricing varies because suppliers use the word “audit” for very different products.

For example, Click Intelligence currently advertises CRO audits from £800 per landing page, including analytics, qualitative analysis, heatmaps, data analysis and recommendations. Credo publishes a £1,500 mini-audit and a £2,500–£5,000 range for its fuller CRO audit. These are supplier prices rather than an industry benchmark, but they show why comparing two quotes by headline price is unreliable.

The ranges overlap because scope matters more than the label. A £1,000 review of one landing page can be deeper than a £2,000 “full-site audit” built mainly from screenshots and generic best-practice comments.

What are you actually paying for?

A useful CRO audit buys diagnosis, not a long PDF.

The work should connect customer behaviour to specific commercial decisions. That normally means examining where people enter the store, what they do next, where they hesitate or leave, and which changes are most likely to matter.

At minimum, a Shopify CRO audit should make clear:

• which customer journeys and templates were reviewed;
• which data sources were used;
• what the biggest conversion problems appear to be;
• how confident the auditor is in each finding;
• which actions should happen first;
• what should be measured after implementation.

If your main symptom is simply a weak headline conversion rate, start by understanding where the Shopify conversion leak actually sits. An audit is much easier to scope once you know whether the problem is traffic quality, product-page persuasion, cart progression or checkout completion.

Why two CRO audits can have completely different prices

1. Analytics depth

A public-store review can identify visible friction. It cannot tell you which device, traffic source, landing page or funnel stage is responsible for the commercial problem.

Once GA4, Shopify analytics, paid-media data or session behaviour are included, the work becomes more diagnostic. It also takes longer.

2. Number of templates and journeys

A ten-product store with one standard product template is different from a large catalogue with several product types, bundles, subscriptions, international markets and multiple landing-page formats.

The right scope is not “every page”. It is the smallest set of journeys that can answer the business question properly.

3. Evidence beyond analytics

Heatmaps, session recordings, customer surveys, support tickets and user testing can explain why a numerical drop exists. They also increase the cost and time required.

Do not pay for every research method automatically. Pay for evidence that reduces uncertainty around an important decision.

4. Prioritisation

A list of 70 issues is not a roadmap. Good audit work distinguishes between broken functionality, high-confidence friction, reasonable hypotheses and cosmetic preferences.

The recommendations should be sequenced by likely impact, confidence, effort and dependency. Otherwise the client still has to pay someone else to decide what to do.

5. Implementation and testing

Some audits stop at diagnosis. Others include wireframes, copy, design direction, development or A/B testing. That is not necessarily better; it is simply a different product.

Ask suppliers to separate diagnosis from implementation in the proposal. It makes quotes easier to compare and reduces the risk of paying for fixes before the problem has been established.

When is a cheap CRO audit enough?

A lighter audit can be good value when the problem is narrow and the business can implement recommendations itself.

It may be enough if you need an experienced second opinion on a product page, collection page, cart or landing page; the store is still relatively small; traffic is too low for sophisticated experimentation; or you want to identify obvious issues before commissioning a larger project.

If the main issue is product-page performance, our guide to seven product-page fixes, in order is a useful pre-audit check. If the drop is later in the journey, use the Shopify checkout optimisation checklist first.

When should you pay for a deeper CRO audit?

Spend more on diagnosis when the cost of making the wrong change is high.

A deeper audit is easier to justify when you already have meaningful traffic and revenue, paid acquisition is expensive, several funnel stages look weak, different teams disagree about the cause, the store has accumulated apps and customisations, or a redesign is being considered without a clear evidence base.

In those situations, a £300 opinion can become expensive if it sends a developer towards the wrong problem. Equally, a £5,000 research programme is wasteful if the checkout button is broken on mobile. Scope should follow uncertainty and commercial risk.

Who a CRO audit is for — and who it is not for

A CRO audit is a good fit for an ecommerce business that already has enough customer activity to expose patterns, has a specific commercial problem to solve, and has the capacity or budget to implement the findings.

It is not automatically the right next step for a brand-new store with almost no traffic, a business with an obviously uncompetitive offer, or a site with fundamental technical failures that need fixing before behavioural analysis means much.

Seven questions to ask before buying a Shopify CRO audit

1. What exact question is the audit trying to answer? “Improve conversion” is too broad.
2. Which pages and journeys are in scope? Get this in writing.
3. Which evidence will you use? Separate analytics, behavioural evidence and expert judgement.
4. Will findings be prioritised? Ask how priority is decided.
5. What will I receive? Report, recording, workshop, wireframes, backlog or implementation plan?
6. Can my own developer implement the recommendations? The answer should not require permanent dependence on the auditor.
7. What happens after the audit? You need a measurement plan, not just a handover.

Warning signs in a CRO audit proposal

• The scope promises to review “everything” without defining the business question.
• The supplier guarantees a conversion uplift before seeing your data.
• The audit is mainly a generic checklist with no store-specific evidence.
• Every finding is presented with the same priority.
• The proposal jumps straight to redesign work before diagnosing the funnel.
• The supplier cannot explain what you will be able to implement without them.

How to compare CRO audit quotes fairly

Put each quote into the same simple framework: problem, scope, evidence, deliverable, prioritisation, implementation and measurement.

The cheaper quote is better value when it answers the question with enough evidence. The more expensive quote is better value when the extra research materially reduces the risk of an expensive wrong decision.

The practical next step

If you know you need a structured review across the store, the Conversion audit + action plan is the direct Mind the Shop route.

If you are not yet sure whether you need a CRO audit, a theme fix, a landing-page change or something else, Send Me Your Mess is the lower-friction starting point. The useful outcome is not buying the biggest audit. It is spending enough to identify the right problem before you spend heavily fixing it.
