What is UX Design?
UX Design (User Experience Design) is the process of creating websites, applications, and products that are easy to use, accessible, and enjoyable for users. It focuses on understanding user needs, behaviours, and pain points to create experiences that help people achieve their goals efficiently. Good UX design considers every aspect of a user's interaction - from first impression to task completion - ensuring a smooth, frustration-free journey.
The foundations of good UX
Understanding these key principles helps you evaluate and improve your website's user experience.
Usability
How easily and efficiently users can accomplish their goals on your website. Good usability means intuitive navigation, clear labelling, and minimal friction.
Key elements:
- Users can complete tasks without confusion
- Error prevention and helpful error messages
- Consistent patterns throughout the site
- Learnability - easy for first-time users
- Efficiency for returning visitors
- Clear visual hierarchy guides attention
Accessibility
Ensuring your website can be used by everyone, including people with disabilities. Good accessibility is also a legal requirement under UK equality law.
Key elements:
- Screen reader compatibility
- Sufficient colour contrast
- Keyboard navigation support
- Alt text for images
- Captions for video content
- Clear, readable fonts and sizing
Navigation
How users find their way around your website. Good navigation is intuitive, consistent, and helps users understand where they are and where they can go.
Key elements:
- Clear, descriptive menu labels
- Logical information architecture
- Breadcrumb trails for orientation
- Search functionality for larger sites
- Maximum three clicks to any page
- Mobile-friendly navigation patterns
UX vs UI: What is the difference?
These terms are often used interchangeably, but they represent different (though related) disciplines. Understanding the difference helps you make better decisions about your website.
UX Design
Focuses on the overall experience - how the product works, flows, and feels.
- -User research and personas
- -Information architecture
- -User flows and journeys
- -Wireframing and prototyping
- -Usability testing
Analogy: The architect who designs the layout, flow, and function of a building.
UI Design
Focuses on the visual appearance - how the product looks and presents itself.
- -Colour schemes and branding
- -Typography and fonts
- -Button and icon design
- -Visual layout and spacing
- -Animation and interaction
Analogy: The interior designer who selects colours, furniture, and decorations.
The key takeaway: UX comes first. A beautiful interface (good UI) is worthless if users cannot figure out how to use it (poor UX). The best products combine excellent UX and UI.
Signs your website has UX problems
These metrics and behaviours often indicate underlying UX issues that are costing you customers and revenue.
High bounce rate
Visitors leaving immediately often indicates confusing layout, slow loading, or content that does not match expectations.
Fix: Improve page speed, ensure content matches search intent, and create clear paths forward.
Low conversion rates
If visitors browse but do not convert, friction in your user journey is likely blocking them.
Fix: Simplify forms, clarify calls-to-action, and remove unnecessary steps from conversion paths.
High support enquiries
Frequent questions about basic tasks suggest your interface is not self-explanatory.
Fix: Add clearer labels, instructions, and tooltips where users consistently get stuck.
Cart abandonment
Users adding items but not completing checkout indicates problems in your purchase flow.
Fix: Reduce checkout steps, offer guest checkout, be upfront about costs, and build trust.
Short session duration
Brief visits suggest users are not finding value or are frustrated with the experience.
Fix: Improve content quality, enhance readability, and ensure smooth navigation between pages.
Mobile complaints
If mobile users struggle, you are alienating over 60% of your potential audience.
Fix: Prioritise mobile-first design, test on real devices, and ensure touch targets are adequate.

Common UX design questions
Everything you need to know about user experience design.
What is UX design?
UX design (User Experience Design) is the process of designing products, websites, and applications that are easy to use, accessible, and enjoyable for users. It focuses on understanding user needs, behaviours, and pain points to create experiences that help people achieve their goals efficiently. Good UX design considers every aspect of a user's interaction with a product, from initial discovery to task completion.
What is the difference between UX and UI design?
UX (User Experience) design focuses on the overall feel and functionality of a product - how it works, flows, and meets user needs. UI (User Interface) design focuses on the visual appearance - colours, typography, buttons, and layout. Think of UX as the architecture of a house (layout, flow, functionality) and UI as the interior design (paint, furniture, decorations). Both are essential, but UX comes first - a beautiful interface is worthless if users cannot figure out how to use it.
Why does UX matter for small businesses?
UX directly impacts your bottom line. 88% of online consumers are less likely to return to a website after a bad experience. For small businesses, every visitor counts - poor UX means lost sales, higher bounce rates, and damage to your reputation. Good UX helps you compete with larger competitors by making your website easier and more pleasant to use. It reduces customer support enquiries, increases conversions, and builds trust with your audience.
How can I improve my website's UX?
Start by watching real users interact with your site - where do they get stuck? Simplify navigation so users can find what they need in three clicks or fewer. Ensure your site loads quickly (under 3 seconds) and works well on mobile devices. Use clear calls-to-action and remove unnecessary steps from key processes like checkout or contact forms. Test with actual users, gather feedback, and make iterative improvements based on data, not assumptions.
Does UX affect SEO and search rankings?
Yes, significantly. Google's Core Web Vitals measure user experience factors like loading speed, interactivity, and visual stability. Websites with poor UX have higher bounce rates and lower dwell times, which signals to search engines that users are not finding what they need. Google explicitly considers page experience as a ranking factor. Good UX and good SEO go hand in hand - both focus on delivering value to users.
What are the most common UX mistakes?
Common UX mistakes include: slow loading times, confusing navigation, poor mobile experience, too many form fields, unclear calls-to-action, intrusive pop-ups, walls of text without visual breaks, auto-playing videos or audio, hidden contact information, and ignoring accessibility. Many of these mistakes stem from designing for the business rather than the user - always put yourself in your customer's shoes.
How much does UX design cost?
UX design costs vary widely. A basic UX review or audit might cost £300-800. Comprehensive UX design for a small business website typically ranges from £1,500-5,000. Enterprise-level UX projects can cost £10,000+. Many web design agencies include UX principles in their standard process. For small businesses, the ROI is significant - fixing UX issues typically increases conversions by 10-30%, quickly paying for itself.
Can I improve UX myself or do I need a professional?
Many UX improvements can be done yourself with research and common sense. Free tools like Google Analytics show where users drop off, and services like Hotjar offer free heatmaps. Simple improvements like clearer navigation, faster loading, and mobile optimisation can be implemented without expert help. However, for complex sites or competitive markets, professional UX expertise helps identify deeper issues and implement strategic solutions that deliver measurable results.
