What is a heading outline?
A heading outline shows the hierarchical structure of your document using HTML heading elements (H1–H6). Proper heading structure helps both users and search engines understand your content organization.
How headings create structure
Heading elements represent content hierarchy, not just visual styling. H1 is typically the main topic, H2 represents major sections, H3 represents subsections, and so on. The hierarchy should flow logically from general to specific topics.
How the tool helps
The Heading Outline tool analyzes your HTML to show the document structure. It identifies potential issues like skipped heading levels (e.g., H2 followed directly by H4) or multiple H1 elements. This helps ensure your content structure reflects your intended information architecture.
Best practices
- Use only one H1 per page, typically for the main title
- Follow a logical progression (H1 → H2 → H3), avoiding skipped levels
- Make heading text descriptive of the content that follows
- Ensure headings reflect content structure rather than visual appearance
