Headings help in defining the hierarchy and the structure of the web page content.

HTML offers six levels of heading tags, <h1> through <h6>; the higher the heading level number, the greater its importance — therefore <h1> tag defines the most important heading, whereas the <h6>tag defines the least important heading in the document.

By default, browsers display headings in larger and bolder font than normal text. Also, <h1> headings are displayed in largest font, whereas <h6> headings are displayed in smallest font.

<h1>HEADING LEVEL 1</h1>
<h2>HEADING LEVEL 2</h2>
<h3>HEADING LEVEL 3</h3>
<h4>HEADING LEVEL 4</h4>
<h5>HEADING LEVEL 5</h5>
<h6>HEADING LEVEL 6</h6>

Importance of Headings

  • HTML headings provide valuable information by highlighting important topics and the structure of the document, so optimize them carefully to improve user engagement.
  • Don’t use headings to make your text look BIG or bold. Use them only for highlighting the heading of your document and to show the document structure.
  • Since search engines, such as Google, use headings to index the structure and content of the web pages so use them very wisely in your webpage.
  • Use the <h1> headings as main headings of your web page, followed by the <h2> headings, then the less important <h3> headings, and so on.
