What you need to know
Automated checks find some accessibility issues but cannot tell whether the page's reading order and announcements make sense. A brief manual test can reveal missing names and confusing navigation.
How to apply it
Try a supported screen reader on your platform, navigate by headings and links, submit a form with an error, and listen for the page title and control names. Record issues as user tasks, not just markup notes.
Common mistake to avoid
Do not assume one screen reader represents every user. Use manual testing alongside keyboard checks, automated tools, and feedback from people with disabilities.
