H1
Most content and landing pages benefit from one clear H1 aligned with the main topic and search intent.

What is an H1-H6 heading structure check?
H1-H6 elements express a page's topic and content hierarchy. This checker rebuilds the outline in document order and flags H1, nesting, empty text and duplicate text problems.
Headings are not merely font-size controls. A clear outline helps search engines understand topic relationships and helps readers and assistive technology navigate the page.
H2-H6
H2 marks major sections and H3 belongs under an H2; do not select levels only for their visual style.
Page heading outline
Show each heading with indentation and provide specific corrections.
Why audit page heading hierarchy?
Templates, rich-text editors and visual components can quietly create multiple H1s, skipped levels or empty tags. These issues may not cause a direct ranking penalty, but they weaken semantics, accessibility and content scanning.
Confirm one primary topic
See whether the page has a clear H1 or accidentally uses several H1 elements.
Find hierarchy breaks
Locate jumps such as H2 to H4 that obscure content relationships.
Remove ineffective headings
Find empty elements and repeated text that does not distinguish sections.
How does the heading checker work?
The server safely fetches the target page once, extracts every H1-H6 from the same HTML response, and applies deterministic structure rules in the browser without requesting the site again.
- 01
Fetch the final page
Validate the public URL, follow safe redirects and read the final HTML.
- 02
Extract headings in order
Preserve the document order, level and visible text of every H1-H6.
- 03
Apply structure rules
Check H1 count, empty headings, skipped levels and duplicate text.
- 04
Build the page outline
Show each heading with indentation and provide specific corrections.
What makes a good H1-H6 structure?
Headings should communicate content relationships rather than serve as a shortcut for larger text. Interpret the report in the context of the page type and content.
H1 summarizes the page
Most content and landing pages benefit from one clear H1 aligned with the main topic and search intent.
Levels express relationships
H2 marks major sections and H3 belongs under an H2; do not select levels only for their visual style.
Text is specific and distinct
Avoid empty headings, consecutive duplicates and vague labels that lose meaning outside their context.
Headings are not styling hooks
Use CSS to enlarge ordinary text instead of adding heading elements with no structural meaning.
H1-H6 heading checker FAQ
Can a page have more than one H1?+
HTML allows multiple H1 elements in some structures, but one clear primary H1 is easier to understand and maintain for most content and SEO pages. The tool marks multiple H1s for review rather than claiming an automatic penalty.
Does skipping from H2 to H4 hurt rankings?+
It is not generally a standalone ranking penalty, but it makes the outline less clear and can hinder assistive technology. Use consecutive levels that reflect real content relationships.
Must the H1 exactly match the title tag?+
No. The title tag serves search results and browser tabs, while H1 serves the page body. They should describe the same topic but may use different wording for their contexts.
Are results saved or published as history pages?+
No. Results remain only in the current page state, are not written to the database, and do not create indexable history URLs.
