Heading Structure (H1–H6)

The hierarchy of HTML heading tags (H1–H6) used to organise page content, with H1 being the primary page title.

Headings provide semantic structure to your content. The H1 is the main topic of the page and should appear once (though Google has confirmed multiple H1s won't penalise you). H2s represent major sections, H3s subsections within those, and so on. Search engines use headings to understand page structure, identify main topics, and extract content for featured snippets.

Best practices: use only one H1 per page that includes your primary keyword, use H2s for major sections (which often include secondary keywords naturally), do not skip heading levels (H1 → H3 without H2), and write headings that describe the content of the section — not just for keywords.

Headings are often pulled verbatim for featured snippets and People Also Ask boxes. Structuring H2s and H3s as questions that users search (using tools like AnswerThePublic or Google's own PAA boxes) increases the chance of capturing these SERP features.
