Accessibility testing ensures your website works smoothly for everyone, including people with disabilities. It evaluates factors like error density, screen reader compatibility, keyboard navigation, and WCAG compliance to identify barriers that affect usability. With 1.3 billion people worldwide living with disabilities, accessible design helps you reach a wider audience, improve user experience, reduce bounce rates, strengthen SEO, and avoid legal risks. It also supports aging users, like Baby Boomers, whose needs change over time. Using free accessibility testing tools, such as the Accessibility Analyzer, helps you create an inclusive, user-friendly, and legally compliant website that delivers long-term business value.
