You've invested in a beautiful website. The colors are on-brand, the typography is crisp, and the hero section looks stunning. But conversions? Flat. Bounce rate? Climbing.
The problem isn't how your site looks — it's how it works.
Here are the seven UI/UX mistakes we encounter most frequently, and how to fix each one.
1. Overwhelming Navigation
The mistake: Mega-menus with 40+ links, dropdown within dropdowns, and navigation that requires a tutorial.
The fix: Follow the 7±2 rule. Primary navigation should have 5 to 9 items maximum. Use clear, descriptive labels instead of clever ones. "Services" beats "Solutions Suite" every time.
❌ Home | About | Solutions Suite | Industries | Resources Hub | Insights | Careers | Partners | Contact | Blog
✅ Home | Services | Work | Blog | Contact
2. Ignoring Mobile-First Design
The mistake: Designing for desktop first, then squeezing everything onto mobile as an afterthought.
The fix: Over 60% of web traffic is mobile. Design for the smallest screen first, then progressively enhance for larger viewports. This forces you to prioritize what actually matters.
3. Poor Call-to-Action (CTA) Hierarchy
The mistake: Every button screams for attention. Three CTAs above the fold, all in different colors, competing for clicks.
The fix: Establish a clear CTA hierarchy:
| Priority | Style | Example |
|---|---|---|
| Primary | Solid, bold color | "Get Started" |
| Secondary | Outlined, subtle | "Learn More" |
| Tertiary | Text link | "View documentation" |
Each page should have one primary action you want users to take.
4. Text Walls Without Visual Breaks
The mistake: Long paragraphs with no headings, no images, no breathing room. The "Terms & Conditions" aesthetic, applied to your entire site.
The fix:
- Break content into scannable chunks with clear headings
- Use bullet points for lists of 3+ items
- Add imagery every 300-400 words of content
- Maintain generous white space — it's not wasted space, it's breathing room
5. Slow, Janky Interactions
The mistake: Animations that lag, hover states that flicker, scrolling that stutters. The uncanny valley of web interactions.
The fix:
- Use CSS transforms instead of changing layout properties
- Keep animations under 300ms for transitions
- Use requestAnimationFrame for JavaScript animations
- Test on mid-range devices, not just your MacBook Pro
"The best animations are the ones users don't consciously notice — they just make the experience feel right."
6. Forms That Feel Like Interrogations
The mistake: A contact form with 12 required fields, including fax number and company revenue range.
The fix:
- Ask for the minimum information needed at this stage
- Use progressive disclosure — collect more details later in the journey
- Add inline validation so users catch errors immediately
- Show a progress indicator for multi-step forms
❌ Name, Email, Phone, Company, Role, Industry, Revenue,
Project Type, Budget, Timeline, How did you hear about us?,
Detailed project description (500 words minimum)
✅ Name, Email, "Tell us about your project" (optional)
7. Inconsistent Visual Language
The mistake: The homepage uses rounded corners, the services page uses sharp squares. Buttons are green here, blue there. Font sizes vary randomly.
The fix: Build a design system — even a simple one:
- Define 3-5 brand colors with specific usage rules
- Choose 2 fonts maximum (one for headings, one for body)
- Set a consistent spacing scale (4px, 8px, 16px, 24px, 32px, 48px)
- Create reusable component patterns (cards, buttons, forms)
