Heading Checker

A Heading Checker extracts H1 through H6 elements in document order so you can review the page's structural hierarchy. It reports H1 count and abrupt level jumps without pretending that every skipped level is automatically an SEO penalty.

Headings help users scan long pages and help assistive technologies understand sections. They also give search engines clearer content structure. Problems usually come from templates choosing heading levels for visual size rather than hierarchy, which can produce multiple unrelated H1s or jumps from H2 to H5.

1. 1Enter a page URL.
2. 2Review headings in the order they appear in HTML.
3. 3Confirm the main page topic has a clear top-level heading.
4. 4Look for jumps that indicate visual styling is driving markup rather than document structure.
5. 5Check whether headings accurately describe the content that follows them.

• One clear H1 is a common, understandable pattern, though HTML does not forbid multiple H1s.
• H2s usually represent major sections beneath the page topic.
• H3 and deeper levels should normally sit inside relevant parent sections.
• A hierarchy issue is a readability and semantics problem, not a numeric ranking score.

• Logo or navigation text marked up as H1.
• Card titles use H4 because of CSS rather than document hierarchy.
• A long article has visually bold paragraphs instead of semantic headings.
• Headings are stuffed with repeated keywords and read poorly.

• Separate visual style from semantic heading level in components.
• Use CSS classes for size rather than choosing H1-H6 for appearance.
• Give major sections descriptive H2s and nest subsections logically.
• Keep headings concise enough to scan while accurately reflecting the section.

• Write headings that work as an outline of the page.
• Use one obvious main topic heading on most pages.
• Keep hierarchy consistent across reusable templates.
• Review mobile rendering so headings remain readable without becoming oversized.

The checker reads heading elements in fetched HTML. It cannot judge whether every heading is editorially useful or detect text styled to look like a heading without semantic markup unless you inspect the page manually.
