Key Takeaways
- Accessibility means people with visual, hearing, motor or cognitive disabilities can use your website.
- WCAG is built on four principles: perceivable, operable, understandable and robust.
- Alt text, colour contrast, keyboard navigation, form labels and captions fix many common issues.
Millions of people in India live with disabilities, and many more have temporary or age-related limitations. An accessible website lets everyone browse, read and buy. It also improves usability, mobile experience and often SEO.
What is WCAG?
The Web Content Accessibility Guidelines (WCAG), published by W3C, are the global standard for web accessibility. They have levels A, AA and AAA; Level AA is the common target. Government websites in India follow GIGW guidelines, which reference WCAG.
The four principles (POUR)
| Principle | Meaning | Example |
|---|---|---|
| Perceivable | Content can be seen or heard | Alt text, captions, contrast |
| Operable | Interface can be used | Keyboard navigation, no time traps |
| Understandable | Content and controls are clear | Simple language, clear errors |
| Robust | Works with assistive technologies | Proper HTML and ARIA |
Common issues and quick fixes
- Missing alt text: describe meaningful images; leave decorative images empty-alt.
- Low colour contrast: ensure readable text against backgrounds.
- Keyboard traps: all menus, forms and pop-ups must work with Tab and Enter.
- Unlabelled forms: every field needs a visible label and clear error messages.
- Videos without captions: add captions and transcripts.
- Vague links: replace "click here" with descriptive text.
- Missing headings structure: use H1–H3 in logical order.
- Auto-playing media: allow users to pause or stop.
How to test
- Run automated checks (Lighthouse, WAVE, axe).
- Navigate your site using only a keyboard.
- Test with a screen reader (NVDA, VoiceOver, TalkBack).
- Check zoom to 200% and mobile layouts.
- Ask real users with disabilities for feedback when possible.

- Clearer structure that also helps SEO and AI understanding
