The “Inappropriate Heading Hierarchy Check” evaluates whether heading levels (<h1> to <h6>) follow a logical, hierarchical sequence.
Example outcome
I found 1 instance in which the hierarchical sequence of heading levels is violated.
Impact
Visual Impairments: Screen reader users rely on heading levels to understand content hierarchy. Skipped levels make it harder to tell what is a sub-topic vs. a new section.
Motor Impairments: Keyboard navigation by heading level becomes less meaningful when heading hierarchy is inconsistent.
Cognitive Disabilities: Logical heading flow helps users understand and mentally organize the page. Skips can cause confusion or misinterpretation.
Neurodivergent Disorders: Clear, predictable structure supports users with ADHD or autism by reducing cognitive overload and frustration.
Fixes
To address inappropriate headings hierarchy:
Locate all the headings that disrespect the hierarchical flow.
Rearrange their levels to ensure a logical sequence.
