Headings (H1-H6) create the outline of your content. Search engines use them to understand your page structure, and users scan them to find relevant information. The Heading Structure Checker analyzes any page's heading hierarchy and flags SEO issues.

Why Heading Structure Matters for SEO

Content hierarchy — Helps Google understand main topics vs subtopics
User experience — Scannable content keeps readers engaged
Accessibility — Screen readers use headings to navigate
Featured snippets — Proper structure increases snippet chances

Heading Structure Best Practices

The Golden Rules

Use exactly ONE H1 per page (your main title)
Don't skip levels (H1 → H3 is wrong, H1 → H2 → H3 is right)
H1 should match or relate to your title tag
Use headings to create a logical outline

How to Use the Tool

Step 1: Enter a URL

Type or paste any webpage URL. The tool fetches the page and extracts all headings.

Step 2: Review the Structure Score

See an overall score based on heading best practices. The tool checks H1 count, skipped levels, and more.

Step 3: View the Heading Tree

See all headings in a visual tree structure, color-coded by level. This shows the content outline at a glance.

Step 4: Check Issues

Review flagged problems: missing H1, multiple H1s, skipped levels, or structural issues. Each comes with a recommendation.

Common Heading Issues

Missing H1 — Every page needs one main heading
Multiple H1s — Confuses the main topic signal
Skipped levels — Going from H1 to H3 breaks hierarchy
No H2s — Long content needs subheadings for structure
