WebAIM Million

An annual accessibility evaluation study conducted by WebAIM (Web Accessibility In Mind) that automatically tests the home pages of the top one million websites against WCAG 2 success criteria. The study has become a key benchmark for measuring the state of web accessibility globally. In 2024, the report found that 96.3% of home pages contained detectable WCAG 2 failures, with the most common errors being low contrast text, missing alternative text for images, missing form input labels, empty links, empty buttons, and missing document language. Over four years of the study, this failure rate has improved by only 1.5 percentage points, highlighting the persistent accessibility gap despite growing awareness and regulation.
