Header Tag Best Practices

Learn how to structure your headings for better SEO and accessibility.

Why Header Tags Matter

Header tags (H1-H6) structure your content hierarchically, helping both search engines and screen readers understand the organization and importance of different sections. Proper heading structure improves SEO rankings and accessibility compliance.

H1 Tag Guidelines

  • Use exactly one H1 per page as the main title
  • Make it descriptive: Clearly convey the page topic
  • Include your primary keyword naturally in the H1
  • Keep it unique: Every page should have a different H1
  • Place it early: Typically near the top of your content

Proper Hierarchy

Headers should follow a logical order: H1 → H2 → H3, etc. Don't skip levels (e.g., jumping from H2 to H4). Each heading level represents a subsection of the level above it. This creates a clear content outline that's easy to navigate and understand.

  • H1: Page title (one per page)
  • H2: Main sections
  • H3: Subsections within H2s
  • H4-H6: Further subdivisions as needed

Frequently Asked Questions

Common questions about header tag optimization.

Can I have multiple H1 tags?

While HTML5 technically allows multiple H1 tags, SEO best practice is to use only one H1 per page. This H1 should represent the main topic and help search engines understand what the page is about. Multiple H1s can dilute your message and confuse ranking algorithms.

What happens if I skip heading levels?

Skipping levels (e.g., H2 to H4) creates a confusing hierarchy that hurts both SEO and accessibility. Screen readers rely on proper heading structure for navigation. Search engines may misunderstand your content organization. Always maintain sequential order.

Should I use headers for styling?

No. Use headers for semantic structure, not visual styling. If you need large text, use CSS instead of choosing a header tag based on size. Headers should reflect content hierarchy, not design preferences.

Do header tags still matter for SEO?

Yes! While not the strongest ranking factor, headers help search engines understand content structure and topic relevance. They improve user experience, increase time-on-page, and support semantic SEO strategies. Proper header usage is a foundational SEO practice.
