There are 6 types of HTML headings ranging from <h1> to <h6> that designers can use for titles and subtitles on a web page. As you may guess, <h1> defines the most important heading.^[1]It represents the page title and usually has the largest font size and weight.

Just like having several cooks in a kitchen is never a good thing, you should avoid using <h1> more than once per page. Otherwise, it may confuse and disorient search engines and screen readers.
