What Is Header Tags?
Header tags are pieces of HTML code that tell a web browser and search engines which text on a page is a title or heading. They are written as H1, H2, H3, H4, H5, and H6. H1 is the main headline, and the numbers go down in importance as they go up.
Definition
Header tags are HTML heading elements that structure page content into clear sections. H1 is used for the main page title, H2 for main section headings, H3 for sub sections under H2, and so on up to H6. They help organize information so people and search engines can understand what each part of a page is about.
Why Header Tags Matters
Header tags matter because they
- Make content easy to scan and read for visitors
- Help search engines understand the topic and structure of a page
- Show which ideas are most important and which are details
- Improve accessibility for screen readers that read headings out loud
- Can help SEO when headings include clear, natural keywords
How Header Tags Works
On a web page, a developer or content editor wraps headings in HTML tags like <h1> or <h2>. For example, the main title might use <h1>Page Title</h1>. Each section below that might use <h2> for its heading. Sub points under a section could use <h3> and so on. Search engines read these tags to understand the main topics and how ideas are grouped. Visitors see them as larger or bold text that breaks the page into clear parts.
