People are visiting. So why aren’t they buying?

Most Shopify stores do not have a traffic problem. They have a leak. Here is where it usually is.

Slow pages.

Every extra second of loading costs you buyers, especially on mobile.

We cut app bloat and heavy images.

Basket drop-off.

Surprise delivery costs and a clunky checkout send people away.

We remove the surprises and the extra steps.

Product pages that do not sell.

Weak images, vague benefits, reviews buried at the bottom.

We rebuild them around why people buy.

Mobile friction.

Most of your traffic is on a phone. Tiny buttons and pop-ups lose sales.

We design for thumbs, not mice.

Why not just hire another agency?

Because your ads and your store are the same problem.

Most agencies do one or the other. So when sales stall, the ads team blames the site and the site team blames the ads, and you pay for the argument. We run both, which means we can tell you which one is actually losing you money and fix it, instead of burning months you could have spent selling.

How soon will I see results from CRO work?

It depends what we are fixing. Some things are a clear problem with a clear fix, and once we have found it the change can go live straight away, so the uplift shows almost immediately. Other things need testing to prove, and how long that takes comes down to what we are measuring and how much traffic you have, anywhere from a couple of days to a couple of weeks.

How much traffic do I need for CRO to be worth it?

There is no single threshold. It depends on your industry, your order values and how your traffic behaves. A Yomp audit tells you what your numbers can support and where the biggest gains are. Lower traffic stores usually get more from fixing obvious leaks than from split testing, because a test needs volume to reach a clear answer.

Do I need my own developer?

No. You can use your own developer if you have one, or Yomp can implement the changes for you at an additional cost, which we quote separately once the audit has shown what needs doing.

I already work with an ads agency. Why should I hire Yomp?

An ads agency working on its own can only see half the picture. When performance dips, the usual answer is that the traffic is fine and the site must be the problem, or the reverse, and you end up paying for the disagreement. Yomp has experience across every part of an ecommerce business, the advertising and the store, so we can pin down exactly where the money is going, whether that is a landing page that needs rebuilding, a checkout that is leaking, or a technical fault quietly stopping people from buying. One team, one answer, and nobody to point the finger at.

Why should we trust your data?

You should not have to take it on faith. Bring your developer, your analyst or whoever knows the site best, and have them check the working. Everything in a Yomp audit is traceable back to the source it came from, so anyone technical on your side can follow it and challenge it. We would rather have that conversation than hand you a number and ask you to believe it, and the fix list is usually better for having been argued over.

Will you run our ads as well as the CRO?

Yes. Yomp runs Google and Meta advertising alongside conversion rate optimisation, which is the point of working with one team rather than two. If you hand your ads over to us, we take the cost of the audit off your first three months.

How much does a CRO audit cost?

A standard CRO audit from Yomp costs £999. If you then hand your advertising over to us, that £999 comes off your first three months.
