UX Design Mistakes to Avoid

User experience (UX) determines whether a visitor stays on your website and takes the desired action, or closes the tab after a few seconds. Even a visually attractive site can lose customers if its usability is poor.

The first and most common mistake is overly complex navigation. A user should be able to find the information they're looking for in three clicks or fewer. The main menu should contain no more than 7 items, and each label must be clear and understandable. Avoid creative terms that confuse the user — call things what they are.

The second mistake is slow loading time. For every additional second a user waits, the conversion rate drops by approximately 7%. Optimize images, use modern formats (WebP, AVIF), implement lazy loading, and minimize JavaScript bundle size. Users are impatient, especially on mobile devices.

The third mistake is excessively long forms. If a contact form has 10 fields, most users simply won't start filling it out. Initially, ask only for essentials — name, email, and message. You can gather additional information later once the contact has been established.

The fourth mistake is an unclear call-to-action (CTA). Every page needs one primary CTA that is visually prominent and clearly states what will happen after clicking. "Submit" is a weak button — "Get a Free Quote" is far more effective and sets clear expectations.

The fifth mistake is insufficient contrast and unreadable text. Small fonts on low-contrast backgrounds guarantee that users will leave. The minimum body text size should be 16px, and contrast must meet the WCAG AA standard (at least a 4.5:1 ratio for normal text).
