H1 Heading

The H1 headingThe H1 is a web page's main heading. It names the central topic, is visible to users and should generally appear only once per page.Open glossary entry → is the top element of the heading hierarchyThe heading hierarchy is the logical nesting of headings from H1 to H6 that structures a page's content, much like a table of contents.Open glossary entry → and describes a page's main topic. For users it confirms they are on the right page, for screen readers it is a key orientation point, and search engines use it for topical classification.

It is important that the H1 is a real <h1> element and not just visually large text in a <div> or <span>. Common problems:

• no H1 at all in the visible main content,
• the logo wrongly marked up as the H1,
• the H1 loaded only via JavaScript.

Best practice is one clear H1 per page. Multiple H1s are technically allowed and not an automatic penalty, but usually worse for clarity. H1 and title should align thematically without needing to be identical.
