5 Common Errors Found in Every Automated Accessibility Audit

Introduction

Digital accessibility is no longer a luxury; it’s a necessity. As global laws and standards tighten around accessibility, businesses are under increasing pressure to ensure their websites and digital products are usable for everyone — including individuals with disabilities. That's where accessibility audits come in. However, while automated accessibility audits provide a useful first glance at your site’s compliance issues, they are far from perfect.

In nearly every automated accessibility audit, a familiar set of problems shows up time and again. These errors are not only common, but they also tend to be critical for accessibility. If not addressed, they can negatively impact both user experience and a business’s risk profile.

This article breaks down the five most frequent accessibility errors found in automated audits, explains why they matter, and shows how accessibility support tools like allyWay can help streamline and scale your accessibility journey — without claiming to ensure legal compliance.

Why Automated Accessibility Audits Are Not Enough

Automated accessibility testing tools are indispensable. They scan volumes of digital content in seconds, flagging issues based on standards like the Web Content Accessibility Guidelines (WCAG). But here’s the catch: automation only gets you so far.

Automated tools can detect about 20% to 30% of WCAG criteria. That leaves a large percentage of accessibility barriers undetected unless you pair automated tools with manual testing, expert audits, and real user experience evaluations.

Nonetheless, automated audits still serve a critical function in your accessibility strategy — especially when powered by intelligent platforms like allyWay, which leverages AI to go beyond basic checks and helps address issues at scale.

Let’s dive into the five most commonly detected errors.

1. Missing Alternative Text for Images

Why it matters:
Alternative (alt) text is essential for screen reader users. It provides context and meaning where visual information is otherwise inaccessible. When images lack meaningful alt text, users with visual impairments are left in the dark.

Common automated audit message:
"Image element missing an alt attribute"

Problem breakdown:

• Decorative images may be flagged unnecessarily if not properly marked.
• Complex images like infographics may need more detailed descriptions than just "alt" tags.
• Auto-generated or empty alt text tags confuse screen readers.

How allyWay can help:
→ allyWay assists in identifying all images lacking alt text and suggests suitable text via contextual AI-based evaluation, helping editors remediate issues more efficiently.

Best practice tips:

• Add informative and concise alt text for all meaningful images.
• Mark decorative images with role="presentation" or empty alt (alt="") correctly.
• Avoid using file names as alt text.

2. Insufficient Color Contrast

Why it matters:
Text with poor color contrast is difficult — or impossible — for users with low vision to read. WCAG defines minimum contrast ratios that ensure readability for most users, yet this is one of the most persistent errors across the web.

Common automated audit message:
"Element has insufficient color contrast ratio"

Problem breakdown:

• Designers prioritize brand colors, neglecting contrast accessibility.
• Dynamic or hover state content often fails contrast checks.
• Background images with text overlay mask poor contrast.

How allyWay reduces this barrier:
→ allyWay includes built-in contrast checking tools and helps suggest contrast-compliant alternatives in real-time. It also applies pre-tested accessibility profiles which can override contrast issues for user-specific needs.

WCAG contrast requirements (AA level):

Actionable steps:

1. Use contrast ratio analyzers during design.
2. Test hover and focus states for interactive elements.
3. Check backgrounds for text overlays.

3. Missing Form Labels

Why it matters:
Properly labeled form elements are fundamental to web accessibility. Without labels, screen readers and keyboard users struggle to understand what information is required, leading to user frustration and abandoned forms.

Common automated audit message:
"Form input element is missing a label"

Implications:

• Non-labeled fields prevent screen reader users from completing transactions or submitting inquiries.
• Placeholder text is incorrectly used as a label.
• Dynamic forms render labels inaccessible or hidden.

allyWay offers a smarter solution:
→ allyWay highlights unlabeled form controls and provides code-level guidance to fix them. Its AI also adapts form field interpretations to different accessibility profiles to improve usability for individuals with cognitive, motor, or visual disabilities.

Form label best practices:

• Use explicit <label for="input-id"> associations.
• Don’t rely on placeholders alone — they disappear on focus.
• Ensure all fields are keyboard and screen reader accessible.

4. Keyboard Navigation Failures

Why it matters:
An accessible website must be fully navigable by keyboard alone. Many users — including those with motor disabilities and vision impairments — rely solely on the keyboard. Poorly implemented navigation traps or skipped sections lock out entire user groups.

Common automated audit message:
"Element is not focusable or skipped in navigation order"

Typical navigation issues:

• Missing focus indicators for buttons or links.
• Modal dialogues trapping focus.
• Dropdowns and menus inaccessible via arrow keys.
• Inconsistent tab order sequence.

How allyWay supports better keyboard UX:
→ allyWay’s platform includes a Keyboard Navigation Profile that optimizes focusable elements and ensures logical navigation patterns. Over 30 accessibility features help correct common oversights without major code rewrites.

Quick fix checklist for keyboard accessibility:
✓ Add visual focus indicators
✓ Ensure modals include aria-modal="true" and focus trapping
✓ Maintain logical tab order using tabindex and form organization
✓ Make all interactive elements reachable with a keyboard only

5. Missing Document Structure and Headings

Why it matters:
A well-organized HTML structure makes content understandable and navigable, especially for assistive technologies. Proper use of headings (<h1>, <h2>, etc.) enables users to skim and jump through sections efficiently.

Common automated audit message:
"Heading levels are skipped or improperly nested"

Problem scenarios:

• Pages with no <h1> tag.
• Inconsistent order (e.g., jumping from <h1> to <h4>).
• Non-descriptive headings like “Click Here” or “More Details”.

allyWay’s approach to semantic issues:
→ allyWay’s AI-powered audit identifies structural errors and outlines where heading levels need adjustments. Semantic clarity is also enhanced through custom accessibility profiles designed for users with cognitive disabilities.

Accessible structure checklist:

1. Use one <h1> per page for major title.
2. Follow a logical heading nesting.
3. Make headings descriptive and brief.
4. Use semantic HTML over generic <div>s where possible.

Additional Accessibility Red Flags in Automated Audits

Aside from the top five, automated scans often reveal these commonly overlooked issues:

• Empty Links or Buttons → Interactive elements need descriptive labels.
• Aria Misuse → Incorrect ARIA attributes can harm accessibility more than help.
• Video Media Missing Captions → Captions are non-negotiable for users who are deaf or hard of hearing.
• Non-responsive Design Elements → Mobile users with disabilities are impacted.

FAQs: Accessibility Audit Errors
