Duplicate Main Landmark Check

Description

The “Duplicate Main Landmark Check” evaluates whether there is more than one main landmark.

Example outcome

I found 2 main landmarks.

Impact

• Visual Impairments: Screen readers may announce multiple main landmarks, confusing the user and making navigation harder.
• Motor Impairments: Keyboard navigation might become more cumbersome as users may need to skip over redundant main landmarks, leading to a less efficient browsing experience.
• Cognitive Disabilities: The page structure may be unclear, leading to difficulty in identifying the main content or distinguishing it from other sections.

Fixes

To address multiple main landmarks:

1. Locate the different main landmarks.
2. Remove the ones that aren’t correctly assigned, moving the content to the correct one if necessary.
