What is Schema.org? A Complete Guide to Structured Data

Have you ever wondered how Google knows to show rich snippets, star ratings, or event details in search results? The answer lies in Schema.org—a collaborative community effort that creates, maintains, and promotes schemas for structured data on the internet.

Understanding Structured Data

Structured data is a standardized format for providing information about a page and classifying the page content. Think of it as a universal language that helps search engines understand what your content is about, not just what it says.

Why Structured Data Matters

When you add Schema.org markup to your website, you're essentially giving search engines a detailed blueprint of your content. This enables:

• Rich Results: Your pages can appear with enhanced features like star ratings, images, and additional information
• Better Understanding: Search engines can more accurately categorize and index your content
• Voice Search Optimization: Structured data helps voice assistants understand and present your information
• Competitive Advantage: Many websites still don't use structured data, giving you an edge

How Schema.org Works

Schema.org provides a collection of shared vocabularies that webmasters can use to mark up their pages. These vocabularies are recognized by major search engines including Google, Bing, Yahoo, and Yandex.

Common Schema Types

There are hundreds of schema types available, but some of the most commonly used include:

• Organization: Information about your business or organization
• Product: Details about products you sell
• Article: Blog posts and news articles
• LocalBusiness: For businesses with physical locations
• Event: Information about events
• Review: Customer reviews and ratings

Implementing Schema.org Markup

The most popular format for Schema.org markup is JSON-LD (JavaScript Object Notation for Linked Data). It's recommended by Google because it's easy to implement and doesn't interfere with your HTML.

Here's an example of how you might mark up a local business:

{
  "@context": "https://schema.org",
  "@type": "LocalBusiness",
  "name": "Schema Advisor",
  "image": "https://example.com/logo.png",
  "address": {
    "@type": "PostalAddress",
    "streetAddress": "123 Main St",
    "addressLocality": "San Francisco",
    "addressRegion": "CA",
    "postalCode": "94105",
    "addressCountry": "US"
  },
  "telephone": "+1-555-123-4567",
  "priceRange": "$$"
}

This structured data tells search engines exactly what your business is, where it's located, and how to contact you—all in a format they can easily understand and display.
