Web design vs UX design: the difference that decides whether your site sells

Picture a website that looks stunning. Beautiful photos, a font you'd want to frame, colours that match the logo perfectly.

Now picture nobody buying anything from it.

That site is a web design success and a UX failure. Both at the same time. And it's more common than you'd think.

"What's the difference between web design and UX design?" is one of the questions I hear most. Usually by a business owner who has already paid for a website and is quietly wondering why it doesn't do much. The honest answer is short: web design decides how your site looks. UX design decides whether it works for the people using it. You need both. But the order you get them in matters more than most people realise.

Here's what each one actually does, how to tell which one your site is missing, and who to hire first.

Think of your website as a house

UX design is the floor plan. Where the front door is. Whether the kitchen is next to the dining room or, for some reason, upstairs behind the bathroom. How many steps it takes to get from the entrance to the thing you came for.

Web design is everything you see once you walk in. The paint, the light, the furniture, the materials. The feeling you get in the first three seconds.

A gorgeous house with a terrible floor plan still makes you walk through the bathroom to get a cup of coffee. A brilliant floor plan with bare concrete walls works fine, but nobody wants to stay. That's the whole relationship in one picture.

What a web designer does

A web designer owns the visual layer and, often, the build:

• Layout, typography, colour and imagery
• Making the site look right on phones, tablets and desktops
• Turning designs into real pages (HTML, CSS, a CMS like WordPress or Shopify)
• Keeping the look consistent with your brand

The question a web designer asks: does this look right, and does it represent the brand?

What a UX designer does

A UX designer owns the experience: what people are trying to do, and what gets in their way.

• Understanding who your visitors are and what they came for
• Structuring pages and menus so people find things without thinking
• Wireframes: the floor plan before any paint goes on
• Testing with real users and fixing where they get stuck
• Looking at the data: where people drop off, and why

The question a UX designer asks: can people do what they came here to do, without friction?

Side by side

A small example with a big price tag

Here's the part that surprised me when I first dug into the research. Baymard Institute has tracked online checkouts for years, and across 50 studies the average cart abandonment rate is 70.22%. Seven out of ten people who add something to their basket leave without paying.

Some of that is just browsing. But look at the reasons people give for leaving during checkout: 18% left because they had to create an account, and 17% because the checkout was too long or complicated. Baymard found the ideal checkout needs around 7 or 8 form fields, while the average one asks for almost 15.

None of those are colour problems. You can't paint your way out of a 15-field form. That's UX.

Where it gets blurry (and why that's fine)

In big companies these are separate jobs: a UX researcher, a UX designer, a UI designer, a front-end developer. Four people, four calendars, one website.

For small businesses that's overkill. What you actually want is one person who thinks like a UX designer and builds like a web designer. Someone who asks "what should this page help people do?" before asking "what colour should the button be?"

That's exactly how I work. I design the structure in Figma first, test the flow, and only then make it beautiful.

The 2-minute self-check: which one is your site missing?

Tick what sounds familiar.

More ticks in the second list? Then a new look won't fix it. That last checkbox is the expensive lesson: a redesign without UX is just a more beautiful version of the same problem.

So who should you hire first?

• Building a brand-new site? Start with UX thinking (who is it for, what should they do), then the visual design. In that order.

• Existing site that looks fine but doesn't convert? Start with a UX review. Find the leaks before you repaint the walls.

• Existing site that works but looks dated? A visual refresh is fine. Just don't move the furniture people already know how to find.

A quick reality check on UX "ROI"

You might have seen the claim that every €1 spent on UX returns €100. I went looking for the source, because I'm curious like that. It traces back to a software engineering textbook quoting a range of "$2 to $100" and a Forrester report about design thinking, not UX specifically. Nobody quoting it shows the actual data.

So I won't promise you 100x. What I can say is more boring and more useful: every friction point you remove is a reason less for someone to leave. That's measurable on your own site, with your own numbers.

Frequently asked questions

Is UX design the same as UI design?

No. UI (user interface) design is the visual and interactive layer: buttons, menus, forms. UX is the whole experience around it. UI sits closer to web design; UX decides what the UI needs to do.

Can one person do both web design and UX design?

Yes, and for small businesses that's usually the best setup. One person, one vision, no handover gaps between "the strategy person" and "the pretty person".

Which is more expensive?

UX work happens earlier and is usually a smaller part of the budget. Skipping it tends to cost more later, because you end up redesigning a site that looked good but didn't work.

Do I need UX design for a small website?

If the site has a goal (a booking, an enquiry, a sale), yes. Even a three-page site has a path from "I landed here" to "I contacted you". UX makes sure that path has no potholes.

How do I know if my website has UX problems?

Watch three people who've never seen it try to do one task, like booking or finding your prices. Don't help them. Where they hesitate is where your UX problem lives.
