Heading Tags

Heading tags (H1 through H6) define the hierarchical structure of a page's content. The H1 typically contains the main title; H2 and H3 organize subsections. Proper heading hierarchy helps users scan content and helps search engines understand the relationship between sections.

Why it matters: Use exactly one H1 per page, followed by a logical H2–H6 hierarchy. Do not skip heading levels (e.g. H1 directly to H4) and do not use headings purely for styling. Assistive technologies use headings as a navigation mechanism, and search engines use them to understand content structure and relevance.
