What is the H1 heading?
SEO Definition and Examples
The H1 heading is the most important heading on the page, used once to name the page's main topic. It is different from the title tag and crucial for SEO.
Full Definition: What is the H1 heading
The H1 heading (<h1>...</h1>) is the HTML tag that denotes the page's main title. Different from the title tag: the title tag is in the <head> and appears in the browser/SERP; the H1 is visible on the page. Best practice: a single H1 per page (with the main keyword), followed by H2s (subheadings) and H3s (sub-points). Google uses the H1 to confirm the page topic. An H1 without a keyword, after a title tag with a keyword = confusion. An H1 with a keyword different from the title tag = weak.
Why Does H1 Heading Matter for SEO?
The H1 reinforces the topic for Google and users. Pages with a relevant H1 rank better. A missing H1 = you lose an on-page optimization signal.
