UX vs UI design: what the difference is and why both matter for a website

🔀 The difference in one sentence

UI (user interface) is the visual part: colours, fonts, buttons, spacing. UX (user experience) is the whole experience: how easily a visitor finds what they want, understands the offer and does what you hope. UI is how the house looks, UX is whether it is easy to find your way around in it.

🧭 What UX does

• Establishes who the users are and what they want.
• Builds the site structure and navigation.
• Draws the wireframe (a layout sketch without colours).
• Reduces friction: fewer clicks, shorter forms, clearer steps.

🖌️ What UI does

• Chooses colours, typography and button style.
• Defines spacing and the look of components.
• Keeps things consistent across all pages.
• Cares about contrast and accessibility.

🪜 A four-step process

1. Research: target group, competitors, keywords.
2. Wireframe: layout of content and calls to action.
3. Visual design and prototype.
4. Testing with real people and on different devices, then fixes.

📈 Why it affects SEO and conversions

Google measures experience through speed, stability and mobile usability. A clear structure helps both people and search engines understand what is on a page. Good UX raises the number of calls and enquiries, and bad UX drives them away. Related: Core Web Vitals and what a good website needs.
