Definition

An H1 tag is the top-level heading element in HTML, used to label the main topic of a page. It is one of six heading levels (`<h1>` through `<h6>`) that browsers and assistive technologies use to convey document hierarchy.

Search engines treat the H1 as one signal among many for understanding what a page is about. Google has stated that pages can have multiple H1s without penalty, and that when the main title is unclear — such as when several large headings compete — Google may fall back to the first prominent heading to generate the title link in search results. Heading order is mainly an accessibility concern: screen readers rely on it for navigation, while Google Search itself does not require strictly semantic ordering.

Examples

• Article page

  A news article uses `<h1>How the federal budget affects renters</h1>` once near the top of the page; the rest of the article is broken up by `<h2>` subheadings for each major section.

• E-commerce product page

  A product page sets its H1 to the product name, such as `<h1>Merino Wool Runner — Charcoal</h1>`, while the site name and breadcrumb appear in smaller surrounding elements.
