HTML Microdata: Making Your Content Machine-Readable

In today's session, we shift our focus from optimizing content for humans to making it more easily understood by machines. Welcome to the world of HTML Microdata!

Introduction to Microdata

Microdata is a way of embedding structured data within your HTML code. It helps search engines and other applications better understand the content and context of your web pages.

Benefits of Using Microdata

Enhances Search Visibility: Microdata provides context to your content, making it eligible for rich snippets in search results.

Improved Accessibility: Microdata aids assistive technologies in understanding your content.

Types of Microdata

  • Schema.org: Most widely adopted and supported by major search engines.
  • Microformats: Simpler and easier to implement.
  • RDFa: More complex but offers more flexibility.

Rich Snippets and Microdata

Microdata helps search engines display rich snippets such as star ratings, event details, and product descriptions in search results, enhancing user engagement.

Implementing Microdata in HTML

To implement Microdata, add itemtype and itemprop attributes to your HTML elements. Example:

<div itemtype="http://schema.org/Person">
  <span itemprop="name">John Doe</span>
</div>

Microdata Schema.org Vocabulary

Schema.org provides a comprehensive vocabulary of microdata types, including Person, Event, Product, and more.

Microdata Examples

Event:
<div itemtype="http://schema.org/Event"> <span itemprop="name">My Birthday Party</span> </div>

Product:
<div itemtype="http://schema.org/Product"> <span itemprop="name">iPhone 14</span> </div>
