H1 Tag

Quick Definition

The H1 tag is the main heading of a page, conventionally used once per page to indicate the primary topic.

In context

H1s should match search intent and contain the primary keyword. Modern Google handles multiple H1s without penalty, but the convention of one H1 per page remains a best practice for accessibility and clarity.
