HTML Metadata Explained: Uses, Examples, and Modern Best Practices

Every webpage has information that is not visible to users directly but tells browsers, search engines, and social media platforms important details about the page. This hidden information is called metadata.

In HTML, metadata is added inside the <head> section of a webpage. Understanding metadata is essential for SEO, page performance, social sharing, and accessibility.

What is HTML Metadata?

HTML metadata is data about your HTML document that helps browsers, search engines, and other services understand the page.

  • Not displayed on the page but crucial for web functionality.

  • Defined using <meta> tags, <title>, <link>, and sometimes <base>.

Common Types of Metadata:

TypePurpose
Title (<title>)Sets the page title displayed in browser tabs and search results.
Description (<meta name="description">)Summarizes page content for search engines.
Keywords (<meta name="keywords">)List of relevant keywords (less important today).
Author (<meta name="author">)Shows page creator.
Viewport (<meta name="viewport">)Ensures mobile-friendly responsive design.
Charset (<meta charset="UTF-8">)Defines character encoding for text.
Open Graph / Twitter CardsUsed for social media sharing (Facebook, Twitter).
Robots (<meta name="robots">)Guides search engines on crawling or indexing.

Modern Importance of HTML Metadata
