What is H1 / H2 / H3?

HTML heading tags (H1, H2, H3) are used to structure content and define the hierarchy of information on a webpage:

H1 Tag:

• The main heading of a webpage
• Typically used once per page for the primary title
• Largest and most prominent heading

H2 Tag:

• Subheadings that divide main content into sections
• Used for major topics within the page
• Second-largest heading size

H3 Tag:

• Sub-subheadings used for subsections under H2 headings
• Provide further content organization
• Third-largest heading size

Heading tags are important for:

• Structuring content for better readability
• Improving SEO by helping search engines understand page content
• Enhancing accessibility for users with screen readers

When using heading tags:

• Maintain a logical hierarchy (H1 > H2 > H3)
• Use them for actual headings, not for styling text
• Limit H1 use to once per page in most cases

Proper use of heading tags helps create well-organized, easily navigable web content.
