HTML Landmark Checker

Check a page for the landmark regions screen reader users navigate by.

Landmarks are the regions screen reader users jump between: main, banner, navigation, contentinfo, complementary, search, form and region. This checker reports which are present, flags duplicates of the ones that should appear only once, and warns when a section or form lacks the accessible name it needs to count as a landmark at all.

Frequently asked questions

Do I need ARIA roles if I use semantic HTML?

No. <main>, <nav>, <header> and <aside> already carry their landmark roles implicitly. Adding role="main" to a <main> element is redundant, and the redundancy is harmless but suggests a misunderstanding worth correcting.
