Heading Tag Analyzer (H1-H6)
Analyze your page's heading hierarchy instantly. Detect missing H1s, multiple H1 tags, skipped levels & empty headings with a visual outline tree.
How to Use Heading Tag Analyzer (H1-H6)
Choose URL Input to analyze a live page, or Paste Raw HTML to check a draft before publishing.
Click 'Analyze Headings' to scan the markup. Heading tags do double duty: they're how screen readers navigate a page for accessibility, and they're one of the clearest signals search engines use to understand a page's topic structure.
Review the visual outline tree showing every heading in hierarchical order. Detect missing H1 tags, multiple competing H1s, skipped heading levels (like H1 straight to H3), and empty headings.
Fix flagged issues in your content and re-check until your outline represents a clean, logical document structure.
Why It Matters
- ✓A single, clear H1 remains one of the strongest on-page relevance signals for both traditional search and AI answer engines.
- ✓Skipped heading levels (H1 straight to H3) break the logical outline that search engines and screen readers rely on.
- ✓Multiple H1 tags dilute topical focus and can confuse which heading is treated as primary.
- ✓Clean heading structure directly supports Featured Snippet and 'People Also Ask' eligibility, since Google frequently pulls snippet answers from well-structured H2/H3 sections.
Key Features
- •Visual heading outline tree with hierarchical nesting
- •Missing and multiple H1 detection
- •Skipped heading-level warnings
- •Empty heading detection
- •Works on live URLs or raw HTML without signup
Frequently Asked Questions
Everything you need to know about Heading Tag Analyzer (H1-H6)
Is it ever okay to have more than one H1 on a page?
HTML5 technically permits multiple H1s, but for SEO purposes a single, clear H1 per page remains the safer, more widely recommended practice — it keeps the topical focus unambiguous for search engines.
What counts as a 'skipped' heading level?
Jumping from an H1 directly to an H3 with no H2 in between, or from H2 to H4, breaks the logical nesting that both screen readers and search engines rely on to understand content structure.
Do heading tags need to contain the exact target keyword?
They should reflect the topic naturally. Keyword-stuffed headings read poorly and can look manipulative to users and search engines alike — a natural, descriptive heading that includes relevant terms performs better long-term.
Why does heading structure matter for accessibility, not just SEO?
Screen reader users often navigate by jumping between headings rather than reading linearly. A broken or skipped hierarchy makes that navigation confusing or impossible — which is both an accessibility failure and a signal search engines pick up on.
