Why Heading Structure Matters
Search engines and screen readers rely on proper heading hierarchy to understand your content. A single H1, logical H2/H3 groupings, and descriptive section titles signal quality to both robots and humans. Use this checker before publishing landing pages, blog posts, and documentation to guarantee a clean outline.
Quick best practices
- Use exactly one H1 that matches the page’s main topic.
- Don’t skip heading levels (H1→H2→H3, never H1→H3).
- Make headings descriptive, not just stylistic labels.
- Include keywords naturally in headings when it makes sense.
- Keep headings short (under ~70 characters) for scannability.
