The HTML heading system provides 6 levels to create a clear content hierarchy on your page. Using these tags correctly helps all users understand your content's organization.

The <h1> tag represents the most important heading on the page and should contain your page title. Think of it as the main subject of your content—what the entire page is about. Since each page should have only one main topic, use only one <h1> element per page. This single top-level heading helps users immediately understand the page's purpose.

Your page title should be descriptive and meaningful. When someone encounters your page, the <h1> heading should clearly communicate what information they'll find there. Screen reader users often navigate through headings, making the <h1> their first major landmark when exploring your content. Search engines also give special weight to this heading when determining what your page is about.
