Poor Mobile Experience

With over 60% of web traffic coming from mobile devices, a non-responsive design is a conversion killer. Tiny text, unclickable buttons, and horizontal scrolling will send users away.

Mobile Optimization Checklist:

  • Test on real devices (not just emulators)
  • Ensure tap targets are at least 48x48px
  • Use responsive typography (minimum 16px for body text)
  • Compress media for mobile networks

CTA Best Practices:

Confusing Navigation

Overly complex menus or buried content frustrate users and increase bounce rates.

Solution:

Limit top-level items to 5-7, use clear labels, and implement breadcrumbs.

5

Weak Content Hierarchy

Wall-of-text syndrome with no visual scanning points.

Solution:

Use headings, bullet points, bold text, and ample white space.

6

Auto-Playing Media

Startles users and creates accessibility issues.

Solution:

Never auto-play videos with sound. Provide clear playback controls.

7

Lack of Trust Signals

No testimonials, security badges, or contact info raises suspicion.

Solution:

Display customer logos, reviews, SSL badges, and physical address.

8

Ignoring Accessibility

15% of the world's population has some disability.

Solution:

Proper contrast, alt text, keyboard navigation, ARIA labels.

9

No Clear Value Proposition

Visitors should understand your offer in 5 seconds.

Solution:

Hero section with concise headline, subhead, and supporting visual.

10

Poor Form Design

Unnecessary fields and bad validation lose leads.

Solution:

Minimize fields, use smart defaults, provide clear labels and errors.

Key Takeaways

Fixing these common website mistakes can dramatically improve your conversion rates and customer satisfaction. Remember:

  • Speed matters: Every second delay can cost you 7% of conversions
  • Mobile-first: Design for thumbs, not mouse pointers
  • Clarity converts: Remove all ambiguity from user journeys

Pro Tip:

Run regular user testing sessions to identify pain points you might have missed. Tools like Hotjar or Crazy Egg can reveal how real users interact with your site.
