What User interface (UI) means
UI is the look and feel of each screen. Consistent, clear interface design builds trust and makes actions obvious. It works hand in hand with UX: beautiful screens still fail if the journey is confusing.
Why it matters for your website
Clear buttons, readable text and familiar menus help visitors act without thinking, which raises form fills and sales. A confusing or dated interface can make a solid business look less trustworthy.
A hypothetical gym changes its "Submit" button to a high-contrast "Start Free Trial" button, and more visitors complete sign-up.
Tips
- Make buttons look clickable and label them with what happens next.
- Keep styles consistent so similar items look and act the same.
- Check color contrast so text and buttons are easy to see.
Common mistakes
- Using trendy designs that hide what is clickable.
- Making tap targets too small for people on phones.
