Accessibility Audit Checklist
A comprehensive checklist for screen readers and keyboard navigation, aligned with WCAG 2.1 AA. Use this page-by-page or flow-by-flow.
Structure & Semantics
- Page has one
<h1>describing the page purpose - Headings follow a logical order (no skipping levels)
- Landmarks exist (
<main>,<nav>,<header>,<footer>) - Landmark names are meaningful (e.g., "Main content")
- Reading order matches visual order
- Content makes sense when CSS is disabled
Keyboard Navigation
- All interactive elements reachable by
Tab - Tab order is logical and predictable
- No keyboard traps
- Focus indicator is clearly visible
- Custom components (dropdowns, sliders, modals) are keyboard-operable
-
Enter/Spaceactivates buttons appropriately -
Escapecloses modals / dialogs - Focus is trapped inside open dialogs
- Focus returns to triggering element after dialog close
- Skip link exists and works
Screen Reader - General
Test with NVDA + VoiceOver if possible
- Page title is descriptive
- All buttons and links have accessible names
- Icon-only controls have labels (
aria-labelor text) - Links are meaningful out of context
- Decorative elements are hidden (
aria-hidden="true") - Content is not announced twice
- Dynamic updates are announced (ARIA live regions where needed)
Forms & Inputs
- Every input has a
<label> - Placeholder is not the only label
- Required fields announced by screen reader
- Error messages announced automatically
- Errors are programmatically linked to inputs
- Instructions are read before the input
- Fieldsets and legends used for grouped inputs
- Validation does not rely on color alone
Modals, Alerts, Notifications
- Modals are announced as dialogs
- Background content is inaccessible when modal is open
- Focus moves into modal on open
- Alerts are announced automatically
- Toasts don't steal focus unexpectedly
Links & Buttons
- Buttons used for actions, links for navigation
- No
div/spanused as buttons without roles + keyboard support - Button labels clearly describe the action
- Disabled buttons are announced correctly
Images & Media
- Informative images have meaningful alt text
- Decorative images have empty
alt="" - Complex images have long descriptions
- Videos have captions (if applicable)
- Auto-playing media can be paused
Visual (Relevant to SR/Keyboard)
- Focus styles meet contrast requirements
- Content does not rely solely on color
- Zoom to 200% works without loss of content
- Reflow at small widths works logically
Responsive & Platform
- Screen reader works on mobile
- Touch targets accessible via SR
- Orientation changes handled correctly
Severity Scale
| Level | Description |
|---|---|
| Critical | Blocks task completion (must fix) |
| High | Major frustration / fails WCAG |
| Medium | Confusing but workaround exists |
| Low | Minor annoyance / improvement |
