Automated and manual coverage
Lighthouse can identify many machine-testable problems, including some label, contrast, structure, and ARIA failures. Other questions require human judgment or assistive-technology testing, including whether alternative text is meaningful, the reading and focus order supports the task, instructions are understandable, and the complete journey works with a keyboard or screen reader.
The reference page and Lighthouse score do not certify A, AA, or AAA conformance. Define the scope, test every applicable success criterion, retain evidence, and obtain appropriate accessibility or legal review when a formal conformance statement is required.
