Good website design is not about looking impressive. It is about helping a visitor understand what you offer, trust you, and take the next step, all within a few seconds. The best website designs share a set of UI/UX practices that have little to do with trends and everything to do with how people actually browse. This guide covers the practices that matter most for modern business websites and web apps.
1. Make the purpose obvious in five seconds
Within moments of landing, a visitor should know what you do, who it is for, and what to do next. Your main heading should say that plainly, not in a slogan. Put one clear primary action, such as "Book a call" or "Get a quote", where people can see it without scrolling. If your homepage needs a paragraph to explain what you do, the design is not finished.
2. Keep navigation simple and predictable
- Limit the main menu to the handful of pages people actually look for: services, work, about, contact.
- Use plain labels. "Services" beats "What we do" beats "Solutions ecosystem".
- Keep the logo linked to the homepage and the menu in the same place on every page.
- On long pages, add clear section headings and, where useful, breadcrumbs so visitors know where they are.
3. Design mobile first
Most visitors arrive on a phone, so design for the smallest screen first and expand from there. That means tap targets large enough for a thumb, text readable without zooming, forms with the right keyboard for each field, and no content hidden behind hover effects that do not exist on touch screens. Test on real devices, not only a resized desktop browser.
4. Build a clear visual hierarchy
Hierarchy tells the eye what to read first. Use size, weight, colour and spacing to separate headings from body text and primary buttons from secondary links. Keep to a small set of type sizes and one accent colour for actions. Generous white space is not wasted space. It is what makes the important things stand out.
5. Treat speed as part of the design
A beautiful page that loads slowly loses visitors before they see it. Performance is a design decision: compress and correctly size images, use modern formats such as WebP or AVIF, limit heavy animations and third-party scripts, and load what is below the fold lazily. Google measures real-user experience through Core Web Vitals: aim for Largest Contentful Paint within 2.5 seconds, Interaction to Next Paint under 200 milliseconds and Cumulative Layout Shift below 0.1.
6. Design for accessibility
Accessible design helps everyone, including people using screen readers, keyboards or a phone in bright sunlight. The essentials, drawn from the Web Content Accessibility Guidelines:
- Sufficient colour contrast between text and background.
- Descriptive alt text on meaningful images.
- Headings in a logical order, one H1 per page, without skipping levels.
- Visible focus states so keyboard users can see where they are.
- Form fields with real labels and helpful error messages.
- Respect for reduced-motion settings.
Many of these also help SEO, because search engines read structure the same way assistive technology does.
7. Make forms short and forgiving
Every extra field costs you enquiries. Ask only for what you need to respond, explain why you need anything sensitive, show errors next to the field that caused them, and never clear a form after a mistake. Confirm clearly when a submission has worked and say what happens next.
8. Build trust into the layout
Visitors look for evidence before they act. Show real work and case studies, client logos you have permission to use, clear contact details and a physical address where relevant. Avoid stock-photo claims and vague superlatives. Specific beats impressive.
9. Use a consistent design system
A design system, meaning a shared set of colours, type, spacing, buttons and components, keeps every page consistent and makes new pages faster to build. It matters even more for web apps and SaaS products, where users repeat the same actions daily and inconsistency feels like bugs.
10. Test with real users, then improve
Watch five people try to complete a key task on your site and you will find most of its biggest problems. Combine that with analytics and search data to see where visitors drop off. Good UI/UX design is never finished; it improves as you learn.
Applying these practices to a portfolio website design
For a portfolio website, the same rules apply with extra emphasis on the work itself. Lead with your best projects, show outcomes as well as visuals, keep project pages fast despite large images, and make contacting you effortless. You can see how we present projects in our own work section.
Frequently asked questions
What is the difference between UI and UX?
UX (user experience) is how the whole journey works: structure, flows and whether people can achieve their goal. UI (user interface) is the visual and interactive layer people see and touch. Good website design needs both.
What makes the best website designs stand out?
Clarity, speed and trust. The best designs make the offer obvious, load quickly and give visitors confident reasons to take the next step.
Do these practices apply to web apps and software?
Yes, often more strongly. Users of business software repeat tasks every day, so small usability gains add up. See our custom software development process for where design fits in.
Should I redesign or improve my current website?
If the structure and platform are sound, targeted UX improvements are often faster and safer. If the site is slow, hard to update or built on a limiting template, a rebuild may pay off. Our builder vs custom website guide can help you decide.
