Conversion · US & UK

Most stores hiring a Shopify CRO agency USA-side cannot run a valid test.

Split testing needs traffic to mean anything, and most merchants do not have enough of it. We will tell you which side of that line you are on before you buy a programme — and if you are below it, what to fix instead.

The teardown, always

The arithmetic nobody shows you

A test that cannot reach significance is a coin toss with an invoice.

This is the part of the industry that most deserves scepticism, and the maths is not complicated. Three things decide whether a testing programme is a real proposition for your store.

You need enough conversions, not enough visitors

Significance depends on how many people complete the action, not how many arrive. A store converting at two per cent needs a great deal of traffic before a test can distinguish a genuine five per cent improvement from noise — often more weeks than the seasonality of your business will hold still for. Below that threshold, a testing programme produces results that look decisive and are not, and every decision made from them is a guess wearing a lab coat.

Most of the win is not a test at all

For the majority of stores the largest available gains are not subtle. A checkout that reveals delivery cost at the final step. Product images that load slowly enough that people leave first. A mobile filter panel that cannot be closed one-handed. A returns policy nobody can find. None of these needs an experiment to justify fixing — they need somebody to go through the funnel on a phone and write down what happened.

The programme that outlives its usefulness

Monthly testing retainers have the same structural problem as monthly content retainers: the deliverable is the activity rather than the outcome, so the tests keep coming whether or not there is anything left worth testing. A store with real traffic and a well-run programme genuinely benefits. A store that has already taken the obvious wins is paying for button colours.

What we can prove, and what we cannot

No published conversion case studies, in any market. The campaign and growth write-ups in our library are drafts and are staying there for now, so this page cannot show you a percentage with a client's name attached. That matters more in this category than in any other on the site, because outcome is what a conversion agency sells — so treat this page as an argument rather than as evidence, and test the argument against your own analytics.

The test you can run on us in five minutes

Open your analytics and find your weekly completed orders. If that number is in the tens, no agency on earth can run you a statistically valid split test inside a sensible timeframe, and any Shopify CRO agency USA or UK merchants are quoted by that proposes a testing programme without asking for that number first has not looked. If it is in the thousands, testing is a genuine proposition and the rest of this page is the smaller half of what we would do for you.

What we would actually do for most stores

Go through your funnel on a mid-range phone, with a real card, and write down every point of friction with a screenshot. Fix those. Measure the before and after on the whole funnel rather than on a variant. It is unglamorous, it is finite, and for a store below the traffic threshold it is the entire opportunity — which is why we would rather sell it to you as a fixed piece of work that ends than as a programme that does not.

And where we would be wrong to take the work

If your store already loads fast, the funnel has been audited, the obvious friction is gone, and you have the volume to test properly — then you want a specialist conversion agency with a track record of published experiments, and you should hire one. That is a real discipline with real expertise in it, our published evidence in it is nothing, and we would say so on the call.

How it runs

Check the arithmetic first.

01

Free conversion teardown

Your funnel walked on a real phone, friction listed with screenshots — plus whether your volume supports testing at all.

02

Fix the obvious

The friction that needs no experiment to justify removing, as a fixed piece of work with a defined end.

03

Measure the funnel, not a variant

Before and after across the whole path to purchase, so the number means something at your traffic level.

04

Test only if the maths allows

And if it does not, we say so and stop rather than selling you a programme that cannot conclude anything.

Money

How conversion work is arranged.

Conversion teardown

Free, written, 48 hours. Your funnel walked on a real device, friction named with screenshots, and a straight answer on whether testing is viable for you.

  • ✓No cost
  • ✓Screenshots, not a score
  • ✓Yours to keep

Fix the friction

The obvious wins implemented as one fixed-scope piece of work with a defined end, measured across the whole funnel.

  • ✓Defined end, not a retainer
  • ✓Before and after measured
  • ✓Store keeps trading

Testing programme

Only for stores whose volume supports it. Monthly, cancellable, and we will tell you when there is nothing left worth testing.

  • ✓Volume checked first
  • ✓Significance stated, not implied
  • ✓We say when to stop

No figures on this site, in any currency — including uplift percentages, which are the figures that matter most here and which we have no published right to quote. Ask any agency for the raw experiment data behind a headline number and see what arrives.

FAQ

Straight answers.

How much traffic do we need before testing is worth it?
The honest answer is a calculation rather than a threshold, and it depends on your current conversion rate, the size of improvement worth detecting, and how long you can hold everything else still. What we can say is that the number is higher than most merchants assume and higher than most agencies mention. Bring your weekly order count to the teardown and we will run it with you — it takes minutes and it is the single most useful thing on this page.
Would a Shopify CRO agency UK based understand British shopper behaviour better?
For the market-specific parts, plausibly yes, and those parts are real: delivery expectations, the returns window shoppers look for, tax-inclusive pricing, and which payment methods feel normal. Those are also mostly knowable rather than intuited, and they show up in your own analytics as drop-off at specific steps. The larger determinant of whether a programme works is your traffic volume, which is not a national characteristic.
What if the teardown says we should not do this?
Then it says so, and it happens often — most stores that ask about conversion optimisation have a speed problem or a checkout problem rather than a testing opportunity. You will have paid nothing and you will have a written list of what to fix instead, which you are free to hand to your existing developer. An audit that always concludes you need the service being audited is a sales document.
Do you use a testing tool, and does it slow the store down?
Any client-side testing tool costs you something in load time, and on a store that is already slow that cost can exceed whatever the test discovers — which is a genuinely perverse outcome and more common than it should be. That is one reason we push speed and friction work ahead of testing rather than alongside it: fix the thing that is costing you conversions before installing something that costs you a little more.
Can you do this alongside our existing agency?
Yes, and the teardown in particular is designed to be portable — it names specific problems on specific pages, and handing it to whoever already builds your store is a perfectly good outcome. We would rather your funnel got fixed than that we won the retainer, partly because it is the right position and partly because merchants remember which agency told them the truth.
Why is there no uplift percentage anywhere on this page?
Because we have not published the work that would justify one, and a number without a linkable case study behind it is decoration. It is also worth knowing that headline uplift figures across this industry are frequently drawn from tests that never reached significance, or from a favourable date range chosen afterwards. Ask for the experiment data. The response tells you most of what you need.
