Heading Hierarchy

Proper heading structure:
H1: Page title (one per page)
H2: Main sections
H3: Subsections under H2
H4-H6: Further subdivisions

Never skip levels (e.g., H2 to H4).

SEO Benefits

  • Helps search engines understand content structure
  • Improves keyword relevance signals
  • Enhances featured snippet eligibility
  • Better accessibility for screen readers
  • Improved user experience and scannability

Common Mistakes

  • Multiple H1 tags on one page
  • Skipping heading levels
  • Using headings for styling only
  • Missing H1 entirely
  • Poor keyword optimization
  • Illogical hierarchy

Optimization Tips

  • Include keywords naturally in H1 and H2
  • Keep headings descriptive and concise
  • Use proper hierarchy (don't skip levels)
  • Make headings scannable
  • Ensure H1 matches page intent

HTML5 Considerations

HTML5 allows multiple H1s in different <section> elements, but for SEO clarity, stick to one H1 per page representing the main topic.

FAQ

Can I use H1 for styling?

No, use CSS for styling. Headings are for structure, not design.

How many H2s should I have?

As many as needed for logical sections—typically 3-6 per page.
