HTML header tags are used to highlight the headings (h1 level) and the subheadings (h2–h6 levels) within the content of a web page. These tags are also called header tags or heading tags. If you skip from h1 to h3, the hierarchy will be broken, and it is not advisable for on-page SEO. Every page should possess only one h1 tag unless it is using HTML5, which allows for more.
