Why it matters
ARIA landmarks help AI agents identify page regions (navigation, main content, footer). This is the same API used by screen readers and is increasingly used by AI browsing agents.
How to fix it
Give each page region a landmark and label repeated landmarks.
-
Make sure that each page has a main, a navigation and a contentinfo landmark.
-
Add aria-label when a landmark type occurs more than once.
<nav aria-label="Main">...</nav> <nav aria-label="Footer">...</nav>
