Designing for Accessibility Is Designing for Conversion

Accessibility is often treated as a legal checkbox or a nice-to-have. This is a massive strategic error. Over 15% of the world's population has some form of disability. If your site isn't accessible, you are effectively closing your doors to 1 in every 7 potential customers — and you're probably making the experience worse for everyone else too.

The "Accessibility = Clarity" Rule

Good accessibility is just good UX. Clearer fonts, better contrast, and logical navigation help everyone — not just those with visual or motor impairments. The same changes that make a site compliant with accessibility standards tend to make it faster to use, easier to understand, and more likely to convert.

The 3-Step Audit

Colour Contrast — The "Squint Test"

If you squint at your "Add to Cart" button, does the text disappear? If your text is light grey on a white background, you are losing sales from everyone over the age of 45 — a demographic with significant purchasing power. Use high-contrast ratios that meet WCAG 2.1 standards.

The "Keyboard Only" Challenge

Unplug your mouse and try to buy something on your site using only the Tab and Enter keys. If you can't reach the Checkout button, neither can a user with motor-skill limitations or someone using a screen reader. Every interactive element should be keyboard-navigable.

Descriptive Alt-Text

Stop naming your images "IMG_5021.jpg." Use descriptive text like "Blue Waterproof Men's Rain Jacket — Front View." This helps screen readers, improves accessibility, and tells Google exactly what to index for image search — a conversion benefit and an SEO benefit simultaneously.

The Business Case

Accessibility isn't a cost centre. It's a market expansion strategy. Every improvement you make for accessibility also reduces friction for mainstream users. The overlap between "accessible design" and "best-practice conversion design" is almost total.
