When a website or app feels easy to use, customers rarely stop to think about it. They simply find what they need, complete the task and move on.
That is the point of good UX/UI design.
For growing businesses, UX/UI is not just about making a website look modern. It affects whether people trust your brand, complete a purchase, return later or contact your support team because they cannot find something. A polished interface is useful, but only when it helps users achieve their goals.
This guide explains what UX and UI mean, how they affect revenue, which common mistakes to avoid and a practical framework for improving your digital products without frustrating existing customers.
What do UX and UI actually mean?
UX, or user experience, is the way a person experiences your website, app or digital service. It includes:
- How easily they find information
- How quickly they complete a task
- Whether the journey feels logical
- What happens when something goes wrong
- How confident and supported they feel
UI, or user interface, is the visual and interactive layer. It includes:
- Layout and spacing
- Colours and typography
- Buttons, menus and forms
- Icons and visual hierarchy
- Responsive behaviour across devices
The two are closely connected. Good UI can make a product clearer, but it cannot rescue a confusing user journey. Likewise, strong UX research may identify the right solution, but the interface still needs to communicate it clearly.
Good design is not decoration added at the end. It is the process of making the right thing easier to use.
Why UX/UI directly affects revenue
A better digital experience can influence revenue in several connected ways.
1. Better conversion
Every extra step, unclear label or confusing form creates another opportunity for someone to leave.
For an online shop, conversion might mean completing a purchase. For a professional services business, it might mean submitting an enquiry, booking a call or downloading a guide. For a software company, it could be starting a trial or upgrading to a paid plan.
Small improvements can make a significant difference when they affect a high-volume journey. Clearer calls to action, shorter forms, better product information and stronger reassurance around payments can all help more visitors complete the next step.
2. Stronger retention
People return to products that help them complete regular tasks without unnecessary effort.
If a customer has to repeatedly search for a feature, re-enter information or work around confusing navigation, frustration builds. Over time, that can lead to lower engagement, cancellations and a search for alternatives.
Retention is particularly important for subscription businesses and digital services. A useful, predictable experience gives customers a reason to stay.
3. More trust
Your website is often one of the first places a potential customer encounters your business. If it loads slowly, behaves unpredictably or hides important information, people may question the reliability of the company behind it.
Good UX supports trust by making key information easy to find and important actions feel safe. Clear pricing, visible contact details, useful error messages, accessible content and consistent design all contribute to confidence.
4. Lower support costs
When customers can complete tasks independently, your team receives fewer “Where do I find this?” and “What do I do next?” enquiries.
This does not mean support should disappear. It means your digital experience should answer common questions before a customer needs to ask them.
What recent redesigns can teach growing businesses
Large brands are not immune to UX mistakes. In fact, their recent redesigns provide useful warnings for businesses of every size.
In 2026, Domino’s redesigned its app and website. As reported by CX Dive, users complained that familiar tasks such as reordering favourites required more taps and scrolling. Some also reported slow loading, crashes, login issues and saved information failing to persist.
The redesign may have looked more polished, but many customers opened the app for one simple reason: to order food quickly. The new experience appeared to prioritise browsing and visual presentation over the high-frequency task users valued most.
MyFitnessPal faced a similar reaction after removing its familiar Diary tab and introducing a new Today view. In a community discussion, long-term users described extra taps, buried information and difficulty viewing their usual data at a glance. Rating trackers also reported a sharp fall following the redesign and associated bugs.
Discord’s evolving mobile and desktop interfaces have also attracted complaints about navigation, spacing, accessibility and familiar controls moving to new locations. Its March 2026 patch notes show the scale of ongoing work required to fix alignment, performance, animation and accessibility issues.
The lesson is not that businesses should never redesign. It is that a redesign must solve real user problems. Changing things simply to make a product feel new can create unnecessary friction and damage trust.
Common UX/UI mistakes to avoid
Forcing a complete redesign
A full rebuild can be expensive and disruptive. It can also make it harder to understand which change caused a problem.
Start with evidence. Identify where users struggle, then improve those areas in manageable stages. A phased approach makes it easier to measure results and correct problems early.
Removing features users rely on
A feature that looks minor to a design team may be central to a customer’s routine.
Before removing anything, review usage data, support requests and customer feedback. Consider whether the feature can be improved rather than deleted. If it genuinely needs to be retired, explain why and provide a suitable alternative.
Prioritising aesthetics over usability
Large images, animations and stylish layouts can strengthen a brand, but they should not slow down essential tasks or hide useful information.
A good interface should look professional and help users understand what to do next. Visual polish comes after clarity, not instead of it.
Skipping user testing
Internal teams know too much about a product. They understand the terminology, the navigation and the intended workflow. New or returning users may not.
Even a small number of usability sessions can reveal confusing labels, hidden features and unexpected behaviour before launch.
A practical UX/UI framework for growing businesses
Use this five-step process to improve an existing website, app or business platform.
1. Research your users
Speak to customers and observe how they currently use your product.
Useful research can include:
- Customer interviews
- Website analytics
- Search data
- Support tickets
- Session recordings
- Accessibility reviews
- Competitor comparisons
Focus on what users are trying to achieve, not just what they say they want. Look for repeated frustrations, workarounds and abandoned tasks.
2. Map the key journeys
Choose the journeys that matter most to your business. These might include:
- Finding a service
- Requesting a quote
- Completing a checkout
- Creating an account
- Booking an appointment
- Managing an existing subscription
Map each step from the user’s starting point to the successful outcome. Mark delays, unnecessary choices, unclear information and error points.
This helps your team prioritise improvements based on business value rather than personal preference.
3. Prototype before building
A prototype can be as simple as a paper sketch, wireframe or clickable screen design. It allows you to explore different solutions before committing development time.
At this stage, focus on structure and flow. Ask:
- Is the next action obvious?
- Can users find important features quickly?
- Does the page contain too much information?
- Are we asking for information we genuinely need?
- What happens if the user makes a mistake?
4. Test with real users
Give people realistic tasks and watch how they complete them. Avoid explaining the interface while they are testing it. If they become stuck, that is useful evidence.
Measure practical outcomes such as:
- Task completion
- Time taken
- Errors made
- Questions asked
- Confidence after completing the task
Test with both new users and existing customers. New users reveal discoverability problems, while existing users highlight risks to familiar workflows.
5. Iterate and release carefully
Use the findings to refine the design, then test again. Once development begins, consider a staged release or feature flag rather than switching everyone at once.
Most importantly, maintain feature parity where possible. If a redesign changes the location of a familiar tool, make it easy to find. If a feature is being retired, communicate the change well in advance, explain the reason and offer an alternative.
Key Insights
- UX/UI design affects conversion, retention, trust and support costs.
- A redesign should solve a user problem, not simply create a new visual style.
- Removing familiar features can damage loyalty quickly.
- Feature parity matters, especially for high-frequency tasks.
- User testing reveals problems internal teams often miss.
- Small, measured improvements are usually safer than a sudden full-scale rebuild.
- Accessibility, performance and reliability are part of good UX, not optional extras.
