Heading Structure Best Practices
✅ DO
- Use one H1 per page - Your main page title
- Follow logical hierarchy - H1 → H2 → H3 (don't skip levels)
- Make headings descriptive - Include target keywords naturally
- Keep hierarchy flat - Avoid going deeper than H3 when possible
- Use headings for structure - Not for styling purposes
- Include keywords - But write for humans first
❌ DON'T
- Multiple H1 tags - Confuses search engines and users
- Skip heading levels - H1 → H3 (missing H2) breaks hierarchy
- Use headings for styling - Use CSS instead of wrong heading level
- Stuff keywords - "SEO SEO Best SEO Practices"
- Make them too long - Keep headings concise and scannable
- Use generic headings - "Introduction", "Content", "More Info"

Can I have multiple H1 tags on a page?
While HTML5 technically allows multiple H1 tags (one per section), SEO best practice is to use only one H1 per page as your main title. This helps search engines understand your primary topic and avoids confusion.
What happens if I skip heading levels?
Skipping levels (e.g., H1 → H3) breaks the document outline and creates accessibility issues. Screen reader users rely on logical hierarchy for navigation. It also sends confusing signals to search engines about content importance.
Should I include keywords in every heading?
Include keywords naturally where relevant, but don't force them into every heading. Your primary keyword should be in the H1, and related keywords in H2/H3 headings. Always prioritize readability and user experience over keyword density.
How deep should my heading structure go?
Most pages work best with H1-H3 levels. Going deeper (H4-H6) is fine for very long, comprehensive content like guides or documentation, but try to keep structure as flat as possible for better scannability.
Does this tool work for dynamic content?
The HTML input method works for any HTML content, including dynamically generated pages. Just view the page source (after JavaScript has loaded), copy the HTML, and paste it into the analyzer.
Can I use this for competitor analysis?
Absolutely! Analyzing competitor heading structures can reveal how they organize content and target keywords. This can inspire improvements to your own content strategy.
