Accessibility — often shortened to a11y — means building sites everyone can use, including people with visual, motor, hearing or cognitive impairments. It's the right thing to do, increasingly a legal expectation in Europe, and a quiet SEO and UX win.
Why it's worth it (beyond compliance)
- A bigger audience: ~1 in 6 people lives with a disability.
- Better SEO: alt text, semantic structure and clear labels help crawlers too.
- Better UX for everyone: captions, contrast and keyboard support help all users.
The quick wins
- Alt text on every meaningful image.
- Sufficient contrast between text and background.
- Keyboard navigation: everything reachable without a mouse, with visible focus.
- Real labels on form fields, not just placeholders.
- Semantic HTML: headings in order, buttons that are buttons, landmarks.
Accessibility isn't a feature you bolt on. It's a quality of how you build — and it shows.
How to check
Run a free audit (Lighthouse, axe), then test the human way: navigate your site with the keyboard only, and try a screen reader for five minutes. You'll find the worst issues fast.
The standard, briefly
WCAG defines levels A, AA and AAA. AA is the practical target for most sites — and increasingly the legal baseline in the EU.
