<h2>Check page headings, with the HTML Headings tool.</h2>
<p>Headings are used to structure the textual content of a web page and are an important on-page SEO factor. The most important heading is the H1 heading followed by the H2 and H3. There are six levels of headings available from H1 to H6.</p>
<p>The H1 heading should contain the main subject of a page. Use only one H1 on a web page.</p>
