Heading is important

Make sure to use the HTML heading tag only for the heading. Don’t use headings just to produce bold or large text.

Search engines use headers to index the structure and content of your web pages.

Because users can quickly navigate your web page through headings, it is important to use headings to present the structure of your document.

h1 should be used as the main heading (the most important), followed by h2 (the next most important), then h3, and so on.
