What is the Heading Structure Analyzer?

Headings (H1 to H6) form the outline of a web page. This tool fetches any URL and draws its heading tree, so you can see every H1, H2, H3 and below in the order they appear, along with warnings for a missing H1, multiple H1s, empty headings and skipped levels.

Why it matters for SEO

Search engines and screen readers both use headings to understand how content is organised. A clear H1 that states the topic, followed by H2s for each main section, helps Google match sections of your page to specific queries and can win featured snippets. A messy outline — headings used only for styling — hides that structure.

How to read your Heading Structure Analyzer results

There should be one H1 describing the page. H2s should read like a table of contents; H3s sit under the H2 they belong to. If you see headings like “Menu” or “Follow us” high in the outline, your theme is using heading tags for layout — swap those to plain styled text.

Expert tips

Put the primary keyword in the H1 and natural variations in H2s.
Write H2s as the questions your readers ask — they double as featured-snippet targets.
Do not skip levels (H2 straight to H4) just for font size; use CSS instead.
Run the SEO Audit afterwards to see headings alongside other on-page factors.

Limitations

Checks only the single URL you enter, as our server fetches it. It does not crawl the whole site, run JavaScript, or see pages behind a login.
