The primary on-page heading that states the main topic of the page to users and search engines.
The H1 is the top-level heading rendered on the page itself, distinct from the title tag that appears in the SERP. It should clearly state the page's main subject, generally align with the target query, and there should usually be one per page to avoid ambiguity about the primary topic. A well-written H1 reinforces relevance, aids accessibility for screen readers, and sets the reader's expectation for what follows.
