Common Website Accessibility Issues and How to Fix Them

By /

Web accessibility ensures that everyone, including people with disabilities, can perceive, understand, navigate, and interact with websites effectively. In 2026, with increasing regulations like ADA requirements for public entities and growing legal risks for businesses, addressing website accessibility issues is more critical than ever.

Despite awareness, studies like the WebAIM Million report show that over 95% of homepages still fail basic WCAG 2.2 Level A/AA standards. Common barriers lead to poor user experiences, lost conversions, and potential lawsuits. This comprehensive guide examines the top website accessibility issues, provides actionable fixes, and includes a practical accessibility testing checklist to help achieve ADA compliance website standards.

Adopting WCAG 2.1 or 2.2 Level AA as the benchmark remains the gold standard for most organizations seeking compliance.

1. Insufficient Color Contrast

Low color contrast between text and background is one of the most prevalent issues, affecting approximately 79-81% of homepages. Users with low vision or color blindness struggle to read content when ratios fall below WCAG requirements (4.5:1 for normal text, 3:1 for large text).

How to Fix It:

  • Use tools like the WebAIM Contrast Checker during design.
  • Ensure sufficient ratios across all states (hover, focus, active).
  • For interactive elements, maintain at least 3:1 contrast.
  • Test in different lighting conditions and with color blindness simulators.
  • Consider providing high-contrast modes or user-adjustable themes.

Implementing strong contrast improves readability for all users and is a quick win for ADA compliance website efforts.

2. Missing or Inadequate Alt Text for Images

Around 54-55% of sites lack proper alternative text for images. Screen readers announce nothing or generic filenames, leaving blind users without context.

How to Fix It:

  • Add descriptive alt attributes to informative images: alt=”Team collaborating on a project at a conference table”.
  • Use empty alt=”” for purely decorative images.
  • For complex images (charts, infographics), provide detailed descriptions or longdesc where appropriate.
  • Avoid keyword stuffing; keep alt text concise and meaningful.
  • Train content creators and implement CMS validation rules.

Regular audits ensure new content meets standards.

3. Unlabeled or Inaccessible Forms

Missing form labels impact nearly 48% of sites. Users cannot easily associate instructions with inputs, creating barriers for screen reader users and those with cognitive disabilities.

How to Fix It:

  • Use explicit
  • For groups, use
    and

    .
  • Provide clear error messages and success states with ARIA attributes like aria-invalid and aria-describedby.
  • Ensure placeholders do not replace labels.
  • Test with screen readers to verify logical flow.

Well-labeled forms boost completion rates and reduce frustration.

4. Empty or Non-Descriptive Links

Empty links (44-45% of sites) or vague text like “Click Here” confuse users and assistive technologies.

How to Fix It:

  • Write descriptive link text that makes sense out of context: “Download the 2026 Accessibility Report PDF”.
  • For icon-only links, use aria-label or visually hidden text.
  • Avoid relying solely on color or position for link identification.
  • Use consistent styling for links (underline + color).

This improves navigation for everyone, especially keyboard and screen reader users.

5. Keyboard Navigation and Focus Issues

Many sites have keyboard traps, invisible focus indicators, or obscured focus (a WCAG 2.2 concern). Not all functionality is operable via keyboard, violating core operability principles.

How to Fix It:

  • Ensure full keyboard accessibility: Tab, Shift+Tab, Enter, arrows, and Escape.
  • Style visible focus indicators (e.g., outline with sufficient contrast).
  • Avoid tabindex values greater than 0 unless necessary.
  • Test for sticky headers or modals that hide focused content.
  • Implement skip links for repetitive navigation.

WCAG 2.2 emphasizes clear focus appearance for better usability.

6. Missing or Poor Video/Audio Captions and Transcripts

Multimedia without alternatives excludes deaf or hard-of-hearing users and benefits many others (e.g., in noisy environments or non-native speakers).

How to Fix It:

  • Provide accurate, synchronized captions for all video content.
  • Offer full transcripts for audio and video.
  • Include audio descriptions for visual information where needed.
  • Use native HTML5 controls or accessible players.
  • Test captions for accuracy and readability.

7. Improper Heading Structure and Semantic HTML

Using headings for visual styling instead of logical structure confuses screen reader navigation. Missing landmarks or poor ARIA usage compounds issues.

How to Fix It:

  • Use headings (H1-H6) to create a proper document outline (one H1 per page).
  • Reserve CSS classes for styling; never skip heading levels for design.
  • Use semantic elements:
  • Validate ARIA roles and avoid overuse (ARIA is often a last resort).

8. Inaccessible PDFs and Documents

Linked documents frequently lack tags, proper reading order, or alt text for images.

How to Fix It:

  • Create accessible PDFs from source with tagged headings, alt text, and logical order.
  • Use tools like Adobe Acrobat Pro for remediation.
  • Provide HTML alternatives when possible.
  • Test with screen readers.

9. Responsive Design and Mobile Accessibility Issues

Content that doesn’t reflow properly on zoom (up to 200-400%) or small touch targets creates problems.

How to Fix It:

  • Use relative units (%, em, rem) instead of fixed pixels.
  • Ensure touch targets are at least 44×44 CSS pixels (WCAG 2.2).
  • Test on real devices and with zoom.
  • Avoid horizontal scrolling on resize.

10. Dynamic Content and JavaScript Barriers

Content updated via JS without proper ARIA live regions or announcements confuses assistive tech.

How to Fix It:

  • Use role=”status”, aria-live, or aria-atomic for dynamic updates.
  • Ensure single-page apps maintain focus management.
  • Provide fallback content and test thoroughly.

Accessibility Testing Checklist

Use this accessibility testing checklist regularly:

Automated Checks:

  • Run tools like WAVE, axe DevTools, Lighthouse, or browser extensions.
  • Check color contrast across the site.
  • Validate HTML semantics and ARIA.

Manual Testing:

  • Keyboard-only navigation test.
  • Screen reader testing (NVDA, VoiceOver, JAWS).
  • Zoom and reflow testing (200%+).
  • Color blindness simulators.
  • Manual review of alt text, links, forms, and headings.

User Testing:

  • Involve people with disabilities in real testing.
  • Conduct periodic expert audits.

Ongoing Maintenance:

  • Integrate accessibility into CI/CD pipelines.
  • Train teams on inclusive design.
  • Monitor third-party content (widgets, embeds).

Documentation: Keep records of audits, remediations, and policies for compliance defense.

Benefits of ADA Compliance Website Efforts

Beyond legal protection, accessible websites improve SEO, boost conversions, enhance brand reputation, and expand audience reach. Many fixes (better UX, faster load times from optimization) benefit all users.

Getting Started in 2026

  1. Perform a full audit.
  2. Prioritize high-impact issues (contrast, alt text, keyboard).
  3. Implement fixes iteratively.
  4. Use overlays or toolbars as supplements (not replacements) for quick user customizations.
  5. Stay updated with WCAG evolutions and legal requirements.

Addressing website accessibility issues is an ongoing commitment. By following WCAG guidelines and using this checklist, you create inclusive digital experiences while mitigating risks. Start today—your users (and legal team) will thank you.
