Heading Structure Analyser.

1. Paste the HTML you want to inspect.
2. Run the analysis and review the heading tree and notes.
3. Fix unclear, empty or misleading headings while keeping the source order meaningful.

The report is a semantic inspection of the heading elements in the pasted fragment. It is a review aid, not an automatic ranking score.

Important considerations

• A skipped heading level is not automatically an SEO penalty.
• The analyser does not know whether a heading is visually hidden or appropriate in the wider page context.
• It does not replace a full accessibility audit.

Worked example

A useful outline usually has one H1 followed by H2 sections, with H3 headings only where they divide an H2 section.
