Web accessibility testing evaluates whether your website or application can be used effectively by people with disabilities, including those who rely on screen readers, keyboard navigation, or other assistive technologies. It matters because inaccessible digital products exclude a significant portion of users, expose organizations to legal risk under laws like the ADA, and limit overall audience reach and brand reputation.
