Design and accessibility: what can be measured objectively

Taste cannot be scored. Contrast ratios, tap target sizes, field labels and keyboard navigation can — and they decide whether the site is usable at all.

Weight in the score: 9/100
checks in this category: 46

Why it matters

These checks run on axe-core and WCAG criteria. Contrast below 4.5:1 makes text unreadable for a real share of your visitors; a button with no accessible name does not exist to a screen reader; a tap target under 24 px gets missed. These cost customers before they cost points.
