What to Test — Screen Reader Checklist

Alt Text on Images — Does the screen reader describe images meaningfully? "Image of a red sofa" not just "image"
Heading Structure — Are headings in logical order (H1 → H2 → H3)? Press H to check
Link Descriptions — Are links descriptive? "Read our ADA guide" not "Click here"
Button Labels — Do buttons say what they do? "Add to cart" not just "Submit"
Form Labels — Does every form field have a visible label? "Email address" not just a blank field
ARIA Labels — Are custom elements properly labeled with aria-label or aria-labelledby?
ARIA Expanded — Does aria-expanded correctly indicate expanded/collapsed state?
Status Messages — Are dynamic updates announced with aria-live or role="status"?
Focus Indicators — Is focus visible when tabbing through the page?
Skip Navigation — Is there a "Skip to main content" link at the top?

ARIA Testing — What to Look For

aria-expanded

aria-expanded indicates whether a collapsible element (like a dropdown or accordion) is expanded or collapsed. Screen readers announce "expanded" or "collapsed" to users.

<button aria-expanded="true" aria-controls="menu">Menu</button>
<ul id="menu">...</ul>

aria-controls

aria-controls identifies which element a control (like a button) controls. Screen readers use this to help users understand relationships.

<button aria-controls="panel1">Show Panel</button>
<div id="panel1">Content</div>

aria-live

aria-live announces dynamic content updates without requiring focus. Use for error messages, notifications, and real-time updates.

<div aria-live="polite">5 items added to cart</div>

aria-label

aria-label provides an accessible name for elements without visible text. Use for icon buttons and custom widgets.

<button aria-label="Close menu">✕</button>

Common Screen Reader Issues and How to Fix Them

Issue What Users Hear How to Fix
Missing alt text "Image" or nothing Add alt="description" to all meaningful images
Missing form labels "Edit text, blank" Use <label for="id">Label</label>
Non-descriptive buttons "Button" (meaningless) Use meaningful text like "Add to Cart"
Skipped headings H1 to H3 without H2 Maintain proper heading hierarchy (H1 → H2 → H3)
Missing ARIA expanded Dropdown state not announced Add aria-expanded="true/false"
Missing aria-live Status updates not spoken Use role="status" or aria-live="polite"
