Why Heading Structure Matters for SEO
HTML headings (H1 through H6) create a hierarchical structure that helps both search engines and users understand your content. A proper heading hierarchy is one of the most important on-page SEO factors.
Best Practices
- One H1 per page — Your H1 should contain the primary keyword and topic of the page.
- Don't skip levels — Go from H1 → H2 → H3, not H1 → H3. Skipping levels hurts accessibility.
- Use headings for structure, not styling — Don't use H3 just because it looks the right size. Use CSS for styling.
- Keep headings concise — Under 60-70 characters is ideal for readability and SEO.
- Include keywords naturally — Place relevant keywords in H2/H3 headings, but avoid keyword stuffing.
Headings and AI Search (GEO)
AI search engines like ChatGPT and Perplexity use heading structure to parse content. Clear, descriptive headings in a question-answer format make it easier for AI to extract and cite your content. This is a key part of Generative Engine Optimization (GEO).
