Website accessibility has moved from a niche compliance topic to a genuine business risk and a real competitive advantage. In Australia, the Disability Discrimination Act already applies to websites, and awareness — along with legal action against non-compliant sites — has been rising steadily. Here's a practical, plain-English guide to what actually matters.
What WCAG actually is
The Web Content Accessibility Guidelines (WCAG) are the internationally recognised standard, built around four principles: content should be Perceivable, Operable, Understandable, and Robust. Most businesses should be targeting WCAG 2.1 or 2.2 at Level AA — the commonly accepted standard for genuine accessibility without extreme technical overhead.
Colour contrast — the easiest big win
Low-contrast text (light grey on white, pale colours on pale backgrounds) fails accessibility standards and is genuinely hard to read for a large share of visitors, not just people with vision impairment. This is usually the single fastest fix on most sites we audit.
Keyboard navigation
Every interactive element — links, buttons, forms, menus — should be usable with a keyboard alone, with a visible focus indicator showing where you are. Test your own site this way: unplug the mouse and tab through it. Many sites break down immediately.
Meaningful alt text on images
Every image that conveys information needs alt text describing what it shows — not the filename, not 'image1.jpg', and not stuffed with keywords for SEO purposes. Purely decorative images should have empty alt text so screen readers skip them cleanly.
Proper heading structure
One H1 per page, followed by a logical H2/H3 hierarchy — not headings chosen for font size. Screen reader users navigate by heading structure to jump to relevant sections, so a broken hierarchy makes a page genuinely harder to use, not just less semantically tidy.
Forms that make sense without a mouse
Every form field needs a properly associated label, clear error messages tied to the specific field, and no reliance on colour alone to indicate a problem (add an icon or text, not just a red border). Broken forms are one of the most common accessibility failures and among the most damaging to conversions generally.
Video and audio content
Captions on video and transcripts for audio content aren't just for accessibility — they also help with SEO, since search engines and AI systems can read text but not watch video. This is a rare case where the accessibility fix and the SEO fix are the exact same piece of work.
Why it's worth doing properly
Beyond legal risk, accessible sites are typically faster, more usable on mobile, and better structured for both search engines and AI answer engines to understand — accessibility and technical SEO overlap more than most businesses realise.
