H1 Tag
The main HTML heading tag that marks the primary title of a web page.
Definition
The H1 tag is an HTML heading element — written as <h1>Your Title Here</h1> — that marks the primary, top-level heading of a web page. There should be exactly one H1 per page. It is typically the most visually prominent heading and is one of the strongest on-page SEO signals available, second only to the title tag. The H1 should clearly describe the page's topic and ideally include the focus keyword.
Why It Matters
The H1 tag is a critical on-page SEO element that tells both search engines and users what the page is about. Google uses it as a strong signal for determining a page's topic and relevance to search queries. Pages with well-optimized H1 tags that include the target keyword tend to rank better than pages with vague, missing, or duplicate H1 headings.
