<h3>Canonical tags</h3>Common failing evidence
<h2>Website audit guide</h2>
<h4>Canonical tags</h4>Possible false positives
- Some application shells intentionally defer the H1 to route content.
- An embedded widget should not be judged as a complete document in isolation.
How to fix it safely
- Use one descriptive H1 for the page's main subject.
- Place major sections under H2 headings and subsections beneath them.
- Use CSS rather than heading levels to control visual size.
How to verify the fix
- Read the rendered headings as a text-only outline.
- Confirm the H1 and section headings match the page's visible subject.
