Quick answer
The most common UX design mistakes are ignoring user intent, cluttered pages, poor mobile design, confusing navigation, slow loading, inconsistent design, weak calls to action, neglecting accessibility and skipping user testing.
Key takeaways
- Design around what users are trying to achieve, not what the business wants to say.
- Clutter, slow pages and confusing navigation drive people away.
- Accessibility is good for everyone, and increasingly expected.
- Testing with real users catches problems your team can't see.
Which mistakes cost the most?
- Ignoring intent: pages built around what the company wants to say.
- Clutter: too many messages and buttons competing.
- Mobile as an afterthought: tiny buttons and hard-to-close pop-ups.
- Confusing navigation: clever labels and deep menus.
- Slow loading: heavy images and scripts.
What else hurts the experience?
- Inconsistent buttons, colours and layouts.
- Vague calls to action such as "Submit".
- Low contrast, missing alt text and keyboard-unfriendly forms.
- Never testing with real users.

Search engines reward pages that satisfy visitors. Clear structure, fast loading and helpful content help rankings and the chance of being quoted in AI answers.
What does good UX look like?
It feels effortless. Visitors find what they need, understand what to do next and trust the business. Our UX audit services find the issues costing you customers.
Why test with five users?
Your team knows the site too well to spot its problems. Watching even five real people try key tasks reveals most issues.
Bottom line
Design for what people are trying to do, keep pages fast and uncluttered and test with real users. Accessibility helps everyone.
