HTML Heading Tags (h1-h6)

HTML provides six levels of heading tags, from <h1> to <h6>. These tags are used to define titles and subtitles, creating a hierarchical structure for your web page's content. A proper heading structure is crucial for both search engine optimization (SEO) and accessibility, as it helps machines and screen readers understand the outline of your document.

The Six Levels of Headings

  • <h1>: The most important heading. It should represent the main title of the page and be used only once per page.
  • <h2>: Represents a major section of the content. There can be multiple <h2> tags on a page.
  • <h3>: Represents a sub-section within an <h2> section.
  • <h4>, <h5>, <h6>: Represent further nested sub-sections. Use them to create a deeper hierarchy as needed.

Best Practices for SEO & Accessibility

  • Maintain Hierarchy: Never skip heading levels (e.g., do not go from an <h1> directly to an <h3>). This breaks the logical structure for screen readers and search engines.
  • Use for Structure, Not Style: Headings should define the structure of your content, not just to make text big or bold. For styling, use CSS.
  • Be Descriptive: Your headings should accurately describe the content of the section that follows.

Browser Compatibility

Heading tags (<h1> to <h6>) are fundamental to HTML and are universally supported by all modern and legacy web browsers, including Google Chrome, Mozilla Firefox, Apple Safari, Microsoft Edge, and Internet Explorer.

Headings Glossary

Heading Hierarchy
The sequential order of headings from h1 (most important) to h6 (least important). Always maintain this hierarchy and never skip levels.
H1 Tag
The most important heading. Should represent the main title of the page and be used only once per page. Critical for SEO.
Document Structure
Headings create an outline of your document. Screen readers use this structure to help users navigate. Search engines use it to understand content hierarchy.
SEO (Search Engine Optimization)
Proper heading structure helps search engines understand your page content and improves rankings. H1 is especially important for SEO.
Accessibility
Screen readers use headings to navigate pages. Proper hierarchy allows users with disabilities to understand and navigate your content effectively.
