8 UI/UX Mistakes That Quietly Cost You Customers (and Easy Fixes)

Good design isn't about fancy animations. It's about making it easy for someone to do what they came to do. When that's hard, people don't send feedback — they close the tab.

Here are eight mistakes we see again and again on business websites and apps, and how to fix each one.

1. Designing for desktop first

Most of your visitors are on phones. If you design on a big monitor and "make it responsive" later, buttons end up tiny, text too small and menus awkward.

Fix: Design the phone version first. Keep tap targets at least the size of a fingertip and body text comfortably readable.

2. No clear next step

A beautiful page with no obvious action is a dead end.

Fix: Give every page one primary button — Call, WhatsApp, Book, Buy — and make it stand out in colour and position.

3. Slow loading

Heavy images, auto-playing videos and too many scripts make pages crawl, especially on mobile data.

Fix: Compress images (use modern formats like WebP), lazy-load what's below the fold and remove plugins you don't need.

4. Too many choices

Ten menu items, five pop-ups and three offers at once overwhelm people.

Fix: Cut the menu to what matters. Group related items. One pop-up at most — ideally none on the first visit.

5. Forms that feel like paperwork

Every extra field is another reason to give up.

Fix: Ask only what you need now. A name and phone number are often enough to start a conversation. Use the right keyboard on mobile (number pad for phone fields).

6. Low contrast and tiny text

Light grey text on a white background may look elegant on a designer's screen, but it's hard to read outdoors on a phone.

Fix: Use strong contrast for text and buttons. Test your pages in sunlight.

7. Hiding the important information

Prices, location, timings and delivery areas buried three clicks deep.

Fix: Put the answers to your top five customer questions where people can see them without hunting.

8. Never testing with real users

What's obvious to you isn't obvious to a first-time visitor.

Fix: Ask three people who've never seen your site to complete a task — for example "book an appointment" — while you watch silently. You'll spot problems within minutes.

Tip: Watch where people hesitate. Every pause is a small design problem waiting to be fixed.

A five-minute UX audit you can do today

Open your website on your phone and go through this list:

• Can you tell what the business does within three seconds of the page loading?
• Is the main button visible without scrolling?
• Does anything jump around while the page loads?
• Can you read every line of text without zooming?
• Does the menu open and close easily with one thumb?
• If you fill in the form, do you get a clear confirmation?

Every "no" is a quick win waiting to be fixed.

Good UX is also good SEO

Search engines pay attention to how people experience your pages. Fast loading, stable layouts and mobile-friendly design are part of how Google evaluates page experience, and pages that answer questions clearly keep visitors reading longer. Fixing UX problems helps both your customers and your visibility in search.

Small changes, big difference

You don't always need a full redesign. Fixing the next step, the speed and the forms often makes the biggest difference. If you'd like an honest UX review of your site, our website development team can walk through it with you.
