Most brand owners I speak to know they need a Shopify designer. What they're less sure about is what a good one actually looks like.
It's an easy gap to fall into. Shopify is visual by nature, so it's tempting to judge designers by their portfolios alone. But a Shopify store is not a graphic design project. It's a sales system. The designer you hire needs to understand conversion, platform architecture, performance, and the customer journey, not just how to make something look polished.
I've been building Shopify stores for over six years. Here's how I'd evaluate a Shopify designer if I were on the other side of the table.
The short answer: A good Shopify designer combines UX and conversion thinking, Shopify-specific platform knowledge, mobile-first design skills, and a working understanding of how design decisions affect speed and SEO. Visual ability matters, but it's the last thing to evaluate, not the first.
The three types of Shopify designer (and which one you need)
Before getting into skills, it helps to understand what type of Shopify designer you're actually looking for. The term covers three quite different roles, and hiring the wrong type for your project is a common and expensive mistake.
Most ecommerce brands need the third type: someone who can design and build in Shopify, not hand off designs to a separate developer. When design and development are split across two people who don't work closely together, the result is usually a store that looks like the design but performs worse, because implementation decisions made in isolation affect conversion in ways the designer never intended.
A genuine Shopify designer works in the platform, understands its constraints and capabilities, and makes design decisions with the build in mind from the start.
The core skills a Shopify designer needs
Here are the skills that separate a Shopify specialist from a general web designer with a few Shopify projects on their CV.
Conversion-focused UX thinking
A Shopify designer should be able to explain why they made every layout decision in terms of what it does for the customer journey. Why is the add-to-cart button above the fold? Why does the product page lead with social proof before price? Why is the mobile checkout a single column?
If a designer talks about aesthetics first and conversion second, that's a mismatch for an ecommerce project. The goal of every page is to move the customer forward. Good Shopify designers design backwards from that goal.
Shopify platform knowledge
Shopify has its own architecture: sections, blocks, metafields, Online Store 2.0, the theme editor, Shopify Functions, checkout extensibility. A designer who understands this builds stores that are editable, maintainable, and scalable. One who doesn't tends to produce stores that look great at launch and become a maintenance headache within six months.
Specific things worth testing in an interview or brief:
- Can they explain the difference between a section and a block?
- Do they design with Shopify's theme editor in mind, so you can edit content without a developer?
- Do they understand metafields and how to use them for product data?
- Have they worked with Shopify Plus and checkout extensibility?
Mobile-first design
Over 70% of ecommerce traffic in the UK comes from mobile devices. A designer who designs for desktop first and adapts for mobile is designing for the minority. Mobile-first means the mobile experience is the primary design, and desktop is the adaptation.
This shows up in specific decisions: thumb-friendly tap targets, single-column product pages on mobile, sticky add-to-cart bars, fast-loading images, and checkout flows that don't require zooming or horizontal scrolling.
Performance awareness
Design decisions directly affect page speed. Large hero images, custom fonts loaded from multiple sources, heavy animation, and third-party scripts all slow a store down. A performance-aware Shopify designer knows this and makes choices accordingly.
The benchmark worth holding designers to: stores built to load in under two seconds on mobile. That's achievable with clean design decisions, optimised assets, and Shopify-native development. It's not achievable when every page is built around full-bleed video backgrounds and a dozen third-party widgets.
How to evaluate a Shopify designer's portfolio
A portfolio tells you a lot if you know what to look for. Most people look at visual style. That's the least useful thing to evaluate.
Instead, look at these:
Does the work show commercial thinking? Can you see clear calls to action, logical page hierarchy, and trust signals placed where they matter? Or does it look like a branding exercise that happens to be on Shopify?
Is the mobile experience considered? Ask to see mobile screenshots or visit the live stores on your phone. If the designer doesn't show mobile work proactively, that's a signal.
Are the stores fast? Run any live stores in their portfolio through Google PageSpeed Insights. A score above 80 on mobile is achievable. Below 50 suggests performance was not a priority. This is one of the most revealing tests you can run.
Can they point to outcomes? Any designer worth hiring should be able to tell you what happened after launch. Not just "the client was happy" but actual numbers: conversion rate, page speed improvement, revenue uplift. If they don't track outcomes, they're not thinking commercially.
Is the work varied or templated? A designer who produces stores that all look the same is working from a template, not from a brief. Good Shopify designers adapt to the brand and the customer, not the other way around.
Where to find a Shopify designer and what to expect to pay
There are three main routes to finding a Shopify designer in the UK.
Shopify Partner directory: Shopify's official partner directory lists agencies and freelancers who have registered as Shopify Partners. It's a reasonable starting point, though registration does not guarantee quality. Use it to find candidates, then evaluate them against the criteria above.
Direct referrals: The best Shopify designers tend to come through word of mouth from other ecommerce founders. If you're in any ecommerce communities or know brands whose stores you admire, ask who built them.
Agency vs freelancer: A freelancer is typically cheaper and suits smaller, well-scoped projects. An agency brings more resource, broader expertise, and better capacity for complex builds, migrations, or ongoing work. The right choice depends on the scope of your project and how much ongoing support you'll need.
What you should expect to pay
The variation within custom builds is almost entirely scope. A five-page store with a standard product catalogue is a different project to a 50-page store with custom product configurators, B2B functionality, and multiple integrations. Always ask for a scope breakdown before comparing quotes.
Questions to ask before you hire
Use these on any discovery call or brief process. The answers will tell you quickly whether you're talking to a genuine Shopify specialist or a generalist who's done a handful of Shopify projects.
- "Walk me through a product page you've designed. What decisions did you make and why?"
- "What's a typical PageSpeed score for your builds at launch on mobile?"
- "How do you approach mobile design: do you start with mobile or adapt from desktop?"
- "Have you worked with Shopify's Online Store 2.0 sections and blocks? How do you build for editability?"
- "Can you share a project where you can point to specific conversion or performance outcomes?"
- "What would you do differently on a project that didn't go as planned?"
That last question is underrated. Every designer who has done real work has had a project that didn't go perfectly. How they talk about it tells you a lot about their honesty, their process, and whether they learn from experience.
If you're looking for a Shopify designer who combines conversion thinking, platform expertise, and a track record of measurable outcomes, get in touch and tell me about your project. I'll give you a straight answer on what your store needs and whether we're the right fit to build it.
