Website Accessibility Checklist: 20 Best Practices for Better User Experiences

Website accessibility is about ensuring that everyone can use your website effectively, regardless of ability, device, or circumstance. Accessible websites provide better experiences, reach broader audiences, and often improve overall usability.

Accessibility benefits users with disabilities, but it also improves navigation, readability, mobile experiences, and engagement for all visitors.

This checklist can help identify opportunities to make your website more inclusive and user-friendly.

1. Use Proper Heading Structure

Headings help users understand content hierarchy and improve navigation.

Best practices include:

  • Only one H1 per page
  • Use H2s for major sections
  • Use H3s for subsections
  • Avoid skipping heading levels

Clear heading structures benefit both users and screen readers.

2. Add Alt Text to Images

Alternative text describes images for people using assistive technologies.

Good alt text should:

  • Be concise
  • Describe important information
  • Avoid keyword stuffing
  • Be omitted for decorative images

3. Ensure Sufficient Color Contrast

Low contrast can make content difficult to read.

Evaluate:

  • Text against backgrounds
  • Buttons
  • Links
  • Form labels

Good contrast improves readability for everyone.

4. Use Readable Font Sizes

Text should be comfortable to read across devices.

Consider:

  • Body text size
  • Line spacing
  • Paragraph spacing
  • Responsive typography

Readable typography improves engagement and usability.

5. Make Navigation Keyboard Accessible

Many users navigate websites without a mouse.

Visitors should be able to:

  • Navigate menus
  • Access links
  • Complete forms
  • Activate buttons

Keyboard accessibility is an important usability consideration.

6. Use Descriptive Link Text

Links should clearly indicate where they lead.

Avoid:

  • Click here
  • Read more
  • Learn more

Instead use descriptive phrases that provide context.

7. Label Form Fields Clearly

Forms should be easy to understand and complete.

Best practices include:

  • Visible labels
  • Helpful instructions
  • Clear validation messages
  • Logical field order

8. Provide Error Messages

Users should understand what went wrong and how to fix it.

Effective messages are:

  • Clear
  • Specific
  • Easy to locate
  • Helpful

9. Avoid Using Color Alone

Information should not rely exclusively on color.

Examples include:

  • Icons
  • Text labels
  • Patterns
  • Visual indicators

This improves accessibility for users with color vision deficiencies.

10. Make Buttons Easy to Use

Buttons should be:

  • Clearly labeled
  • Large enough to tap
  • Visually distinct
  • Easy to identify

This is especially important for mobile users.

11. Support Screen Readers

Assistive technologies help many users navigate websites.

Consider:

  • Semantic HTML
  • Proper labels
  • Meaningful headings
  • Logical content order

12. Ensure Responsive Design

Accessible websites should work across devices.

Review:

  • Mobile layouts
  • Tablet experiences
  • Desktop displays
  • Orientation changes

13. Avoid Autoplay Media

Unexpected audio or video can create barriers.

If media automatically starts:

  • Provide pause controls
  • Allow users to stop playback
  • Offer captions where appropriate

14. Provide Captions for Videos

Captions improve accessibility and usability.

They help:

  • Users with hearing impairments
  • Mobile users
  • Visitors in quiet environments
  • Non-native speakers

15. Maintain Consistent Navigation

Consistency reduces cognitive effort.

Users should know:

  • Where they are
  • How to move around
  • What to expect

16. Use Adequate Spacing

Whitespace improves readability and comprehension.

Review:

  • Paragraph spacing
  • Margins
  • Padding
  • Line height

17. Test Without Images

Content should remain understandable even if images do not load.

Ask:

  • Does the page still make sense?
  • Are important messages preserved?
  • Can users complete tasks?

18. Check Focus Indicators

Keyboard users should always know which element is selected.

Focus states should be:

  • Visible
  • Consistent
  • Easy to identify

19. Simplify Language

Clear communication benefits all users.

Consider:

  • Short sentences
  • Simple wording
  • Descriptive headings
  • Logical structure

20. Conduct Accessibility Reviews Regularly

Accessibility is an ongoing process.

Businesses should review websites:

  • After redesigns
  • Before launches
  • After major updates
  • As part of routine maintenance

Continuous improvements help maintain better experiences over time.
