SEO
Heading Hierarchy (H1, H2, H3)
The short answer
Heading hierarchy is the structure of a page's titles and subtitles — one H1 as the main title, followed by H2s and H3s that organize the content beneath it in order.
Full explanation
A clear hierarchy helps both search engines and AI models understand how a page is organized, and phrasing those headings as real questions ("How much does SEO cost?") makes each section more likely to be extracted as a direct answer.
