What our ADA Website Analyzer Plugin scans for:

WordPress ADA Accessibility Scanner
Scan Elements & Checks

Missing <main> landmark
Ensures a primary content region exists for screen readers.
Missing page <title>
Flags pages without a proper, descriptive <title>.
Missing <h1> heading
Checks that each page includes a top-level heading.
Improper heading hierarchy
Detects skipped heading levels (e.g., <h1> → <h3>).
Empty or repetitive links
Finds <a> tags that contain no text or redundant link text (e.g., multiple “click here”).
Links missing aria-label
Flags navigation or icon-only links without descriptive labels.

Images missing alt attributes
Detects <img> tags without alt or with empty alt="".
Decorative images not marked properly
Flags images missing role="presentation" or empty alt text when appropriate.
Linked images missing descriptive alt
Ensures logos or image links have alt text that explains the link purpose.
Video and audio elements without captions or transcripts
Scans for <video> and <audio> elements missing <track> or caption text.

Low color contrast
Measures text color vs. background color to ensure 4.5:1 (normal text) or 3:1 (large text).
Text embedded in images
Detects text baked into images (which fails contrast and resizing rules).

Form fields missing <label> or aria-label
Checks all <input>, <textarea>, and <select> elements.
Placeholder-only forms
Flags fields that rely solely on placeholder text (not accessible).
Buttons with no text or label
Finds <button> or <input type="submit"> without a readable label.

Incorrect or missing ARIA roles
Flags invalid ARIA attributes (e.g., aria-role instead of role).
ARIA elements missing aria-label or aria-labelledby
Checks that landmark roles like navigation, banner, main, etc., are properly labeled.
Duplicate IDs
Ensures each element ID is unique (important for ARIA references).

Viewport meta tag missing
Confirms the presence of <meta name="viewport" ...>.
Zoom disabled
Flags pages that block user scaling (user-scalable=no).

Autoplaying media without controls
Finds autoplaying <video> or <audio> without pause controls.
Links opening new tabs without notice
Detects links using target="_blank" missing aria-label or rel="noopener".
Flashing or blinking content
Identifies <blink>, <marquee>, or CSS animations that flash >3 times/sec.
Non-descriptive button text
Flags buttons like “Submit,” “OK,” or “Click Here” without context.
Non-semantic clickables
Detects <div> or <span> elements with click handlers but no role or label.

Each issue is categorized and displayed in the results table as:

High Severity: Violates core WCAG 2.1 AA (e.g., missing alt, missing labels).
Medium Severity: Potential usability issues (e.g., heading order, repetitive links).
Low Severity: Best-practice improvements (e.g., empty ARIA roles, meta tags).
