Some design mistakes are obvious; others quietly undermine conversion without being immediately apparent. Here are ten worth specifically auditing your site against.
1. Unclear or Missing Calls to Action
Visitors shouldn't have to search for what to do next — unclear or absent calls to action directly cost conversions regardless of how strong the surrounding content is.
2. Inconsistent Branding and Visual Design
Inconsistency across pages creates a subtle but real sense of unprofessionalism, undermining the trust needed for conversion.
3. Overly Complex Navigation
Navigation trying to surface everything equally overwhelms visitors and obscures the paths that actually matter for conversion.
4. Poor Color Contrast and Readability
Text that's difficult to read due to poor contrast or overly small sizing creates friction that causes visitors to abandon rather than struggle through.
5. Slow-Loading Pages
Performance issues cost conversions before visitors ever fully see your content or offer.
6. Missing or Weak Mobile Optimization
A poor mobile experience directly costs a significant share of potential customers given current mobile traffic volumes.
7. Autoplaying Media With Sound
Unexpected audio or aggressive autoplay video creates immediate, negative friction that drives visitors away.
8. Forms That Ask for Too Much Information
Unnecessary form fields reduce completion rates without providing proportional value to justify the added friction.
9. Lack of Genuine Trust Signals
Missing reviews, unclear policies, or absent contact information all increase hesitation at the exact moments that matter most for conversion.
10. Ignoring Accessibility
Poor accessibility excludes genuine potential customers and, particularly for larger sites, can carry real legal risk beyond the direct conversion cost.
