Heading or Header Tag

Heading tags, also called Header Tags, are HTML elements used to identify titles and subtitles within the content of a web page.

They are hierarchically ordered from H1 to H6, with H1 indicating the most important heading and H6 the least important.

Headings are important for website accessibility and usability, but they also play a role in SEO, as they help search engines understand the structure and content of the page.
