Header tags, also called heading tags, are HTML elements used to define the headings and subheadings on a webpage. They help organize and structure the content of a webpage. Here’s a breakdown of how each header tag is used:

  1. <h1>: The <h1> tag represents the main heading of a webpage. It is used once per page and should describe the main topic or purpose of the page. Search engines often give significant importance to the content within this tag.

  2. <h2> to <h6>: These tags represent subheadings and create a hierarchy within the content. The lower the number, the more important the subheading is. It’s best to use them in a logical order, with <h2> being the most important subheading after the <h1>.

  3. <h2>: Used for major section headings on a webpage, separating different sections of content.

  4. <h3>: Typically used for subsection headings within a major section. It breaks down the content further and helps readers navigate the page.

  5. <h4> to <h6>: These tags are used for subheadings within subsections, providing a deeper level of organization and structure to the content.

Using header tags correctly helps users understand the structure of a page and also gives search engines clues about the organization and importance of the content.
