Heading tags (H1-H6) structure your content hierarchically, making it easier for both users and search engines to understand your page. They create a clear outline of your content, with H1 being the main title and H2-H6 providing subsections.
Why Heading Structure Matters for SEO
- Search Engine Understanding: Headings help Google understand your content hierarchy and main topics
- User Experience: Clear headings make content scannable and easier to read
- Keyword Signals: Headings are weighted more heavily than regular text for SEO
- Featured Snippets: Well-structured content is more likely to appear in featured snippets
- Accessibility: Screen readers use headings to help users navigate pages
Heading Tag Hierarchy Best Practices
- Use One H1: Each page should have exactly one H1 tag (the main topic)
- Don't Skip Levels: Go from H1 to H2 to H3 (don't jump from H1 to H3)
- Logical Structure: Headings should follow a logical outline structure
- Include Keywords: Use relevant keywords naturally in your headings
- Be Descriptive: Headings should clearly describe the section content
- Keep Consistent: Use similar heading styles throughout your site
Optimal Heading Length
H1: 20-70 characters (main page title)
H2: 20-60 characters (major sections)
H3-H6: 15-50 characters (subsections)
