On-Page SEO
H1 heading
An H1 heading is a top-ranked semantic heading that normally identifies the main content or a top-level section of a document.
What it means
HTML can contain more than one H1 in valid structures, while accessibility guidance commonly uses one clear main H1 followed by lower-ranked subsections. The appropriate pattern depends on the document, not a universal SEO penalty rule.
Why it matters
A clear main H1 helps users confirm the page subject and navigate the heading outline. Google may consider prominent headings when generating title links, but H1 wording remains one of several sources.
Example
An article template renders one H1 for the article title, H2 headings for major sections and separate consistently ranked headings in navigation and footer regions.
Common mistakes
Do not claim multiple H1 elements automatically cause a ranking penalty, hide an H1 for keywords or duplicate the site logo as the main article heading. Avoid leaving several equally prominent titles.
