Heading Tags (H1-H6)
HTML elements (H1-H6) that define the hierarchical structure of page content.
Heading tags (h1 to h6) mark the sections of a page and their relative importance. They give assistive technology a navigable outline and give search engines the boundaries of each topic on the page. Choose the level by the section's place in the hierarchy, and control the visual size with CSS instead.
Definition
Heading tags (H1 through H6) are HTML elements that define the hierarchical structure of content on a page. H1 is the main heading, H2 for major sections, H3 for subsections, and so on.
Best practices: one H1 per page (matching the topic), H2s for major sections, and a logical hierarchy (never skip levels like H1→H3). Heading tags help both Google and screen readers understand content structure.
Why It Matters
Proper heading structure helps Google understand your content's topic hierarchy. Pages with well-structured headings are more likely to win featured snippets and rank for related subtopics.
