H1
The top-level heading on a page. One H1 per page, matched to the primary topic and query intent.
H1 tags signal the page's primary subject. Best practice is one H1 per page, matching the primary query intent, and visually prominent (typically the page's main headline).
H2s and H3s structure the rest of the content hierarchically. Engines use heading structure to understand topic flow.
