Purpose

Level 1 headings (<h1>) represent the main heading of a page or section.

Prior to HTML5, the logical outline of a page’s contents was based purely on the 6 heading levels <h1> - <h6>. It was therefore customary to only have a single <h1> on the page to represent the page’s title (and often the heading text would match that of the <title> element as well).

HTML5 introduced sectioning elements and the outline algorithm which means you could technically have many <h1>s on a page (or unusual-looking jumps in heading level) and use sectioning elements structure them into a sensible outline. However, to date none of the main web browsers support the outline algorithm in any meaningful way.

For this reason and better compatibility with pre-HTML5 browsers, bots and tools it makes sense to continue relying on the 6 heading levels to express your page’s outline, even if you are making use of the sectioning elements. This advice is also echoed in the HTML5 spec’s “Headings and sections” chapter.

Best practice

  • Have one level 1 heading per page, containing the page’s title
