What Is UX/UI design? Definition & Guide

UX/UI design is the design of the user experience (UX, how it feels to use a product) and the interface (UI, how it looks): together they make a site or app easy, pleasant and effective.

UX and UI: two sides of the same work

UX (User Experience) is about logic: structure, journeys, clarity of steps, ease of completing an action. UI (User Interface) is about appearance: colours, typography, buttons, spacing. A beautiful but confusing site has good UI and bad UX; a functional but ugly one is the opposite. You need both.

Why it matters for your site

• Conversions: a clear journey turns more visitors into customers.
• Trust: a polished interface signals professionalism.
• Accessibility: good design is usable by everyone, on every device thanks to responsive design.

From design to build

The design is then turned into code on the front-end. Good UX/UI reduces frustration, lowers bounce rate and even improves SEO. In our e-commerce and custom sites we craft design from business goals, not just aesthetics.
