Free Heading Analyzer

Enter a URL or paste HTML content above to extract and analyze the heading structure. The tool maps out every H1 through H6 tag, visualizes the hierarchy as a tree, and flags issues like skipped heading levels, missing H1 tags, or multiple H1s on a single page.

Why heading structure matters

Headings provide the semantic outline of your content for both search engines and users. A well-structured heading hierarchy helps Google understand the topical structure of your page and which sections are most important. Screen readers also rely on headings for navigation, making proper structure an accessibility requirement as well as an SEO best practice.

Common heading issues

• Missing H1 tag — every page should have exactly one H1
• Multiple H1 tags — dilutes the primary topic signal
• Skipped heading levels (e.g., H2 to H4) — breaks the logical outline
• Headings used for styling instead of structure
• Overly long headings that bury the keyword

Heading optimization tips

Use a single H1 that clearly states the page topic and includes your primary keyword. Organize subsections with H2 tags and use H3 tags for sub-points within those sections. Keep headings descriptive but concise. Avoid using heading tags purely for visual formatting — use CSS classes instead. Think of your heading structure as a table of contents that should make sense on its own.

Auditite scans heading structure across your entire website, identifies pages with hierarchy problems, and can automatically suggest improved heading structures using AI agents.
