A Google Lighthouse Accessibility score of 100 is a useful indicator, but it should not be treated as proof that a website is fully accessible or compliant. Lighthouse can automatically detect common issues such as missing alternative text, poor color contrast, unlabeled controls, and inaccessible names, but many WCAG 2.1 and WCAG 2.2 requirements depend on context and human judgment. Problems involving keyboard focus, screen reader announcements, meaningful alternative text, dynamic content, form errors, and complete user journeys can remain even when automated tests pass. Tools such as Axe DevTools and the WAVE accessibility checker can provide additional insights, but they also cannot replace manual testing. A stronger accessibility compliance process combines automated testing, manual WCAG reviews, assistive technology testing, and evaluation of the tasks users actually need to complete.
