Heading Structure Analyzer
See your content outline as Google sees it. Optimize for accessibility and logical flow.
Why heading hierarchy matters
Search engines use headings to understand the OUTLINE of your content. A clear H1-to-H6 structure tells Google exactly what acts as a main topic and what is a sub-topic.
What this analyzer reveals
- Visual Logic: See if your content flow actually makes sense when stripped of design.
- Accessibility: Screen readers rely entirely on heading jumps navigation.
How this Heading Analyzer Works
This tool parses your HTML and extracts all heading tags (`h1` through `h6`). It visualizes the nested structure (indentation) so you can instantly see if your content follows a logical hierarchy.
- Hierarchy Check: We flag skipped levels (e.g., jumping from H2 to H4).
- H1 Validation: We ensure you have exactly one H1 tag.
- Accessibility Audit: We check if headings form a navigatable outline for screen readers and AI crawlers.
Why it Matters for GEO
AI Scans the Outline
Generative AI models (and Google) use your heading structure to understand the "skeleton" of your article. If the skeleton is broken (e.g., missing H2s), the AI might misunderstand the relationship between your topics.
Featured Snippets
Clear H2/H3 structures are often directly lifted by Google for "Featured Snippets" and by Perplexity for citations. A clean outline = better understanding.

Frequently Asked Questions
The H1 tag represents the main topic of the page. Having multiple H1s confuses search engines about the primary focus. Think of it as the book title—you only have one.
Yes. Jumping from H2 to H4 breaks the accessibility tree (used by screen readers) and confuses the semantic structure. Always nest logically: H2 -> H3 -> H4.
Ideally, headings should be concise but descriptive. Extremely long headings (2+ lines) look like paragraph text to an AI, while 1-word headings often lack context.
