HTML Document Metadata – Title, Head, and Meta Tags Explained

Mastering the document structure of an HTML page is essential for building well-organized, search-friendly websites. The <head> section, including the title and meta tags, plays a critical role in SEO, accessibility, and rendering behavior.

In this guide, you’ll learn:

  • How to use the <title>, <head>, and <meta> tags
  • Best practices for metadata structuring
  • How these elements impact SEO and browser behavior

1. HTML Title Tag

The <title> tag defines the page’s title that appears:

  • In search engine results
  • In social media previews

Syntax:

Explanation:

  • Each HTML page must include one <title> tag inside the <head>.
  • Keep it concise (50–60 characters) for SEO.

2. HTML Head

The <head> tag holds all non-visible page info such as:

  • Page title
  • Character encoding
  • Stylesheets and JavaScript links
  • Meta tags
  • Favicon links

Example:

<head>

  <meta name="description" content="Learn about HTML metadata elements.">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">

</head>

Explanation:

<meta name="keywords" content="HTML, metadata, title, head, meta tags">
<meta name="author" content="Jane Doe">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
