Structured Data

What are Structured Data?

Structured data are special HTML markups that help search engines better understand website content. They use a standardized format to describe information about products, articles, events, and other entities.

Benefits of Structured Data

Structured data offer numerous benefits for SEO and user experience:

  • Rich Snippets: Better representation in search results
  • Better Understanding: Search engines understand content more precisely
  • Higher CTR: More attractive snippets lead to more clicks
  • Featured Snippets: Chance for prominent placement
  • Voice Assistants: Tuning for voice search

Schema.org - The Standard

Schema.org is the initiative for structured data supported by Google, Microsoft, Yahoo, and Yandex. It offers over 800 different schema types for various content categories.

Important Schema Types

JSON-LD - The Preferred Format

JSON-LD (JavaScript Object Notation for Linked Data) is Google's preferred format for structured data. It offers several advantages:

Benefits of JSON-LD

  1. Easy Integration: Can be placed in <head> or <body>
  2. Maintainability: Easy to edit and update
  3. No HTML Changes: No need to modify existing HTML code
  4. Validation: Easy verification with Google tools

JSON-LD Example

{
  "@context": "https://schema.org",
  "@type": "Article",
  "headline": "Structured Data for SEO",
  "author": {
    "@type": "Person",
    "name": "John Doe"
  },
  "datePublished": "2025-01-21",
  "dateModified": "2025-01-21",
  "description": "Comprehensive guide to structured data"
}

Rich Snippets and Rich Results

Rich snippets are enhanced representations in search results enabled by structured data.

Types of Rich Results

  • Article Snippets: With author, date, and rating
  • Product Snippets: With price, availability, and reviews
  • FAQ Snippets: With questions and answers
  • How-To Snippets: With step-by-step instructions
  • Event Snippets: With date, location, and price

Implementation of Structured Data

1. Select Schema Type

Choose the appropriate schema type based on your content:

  • Websites: WebPage, WebSite
  • Articles: Article, BlogPosting, NewsArticle
  • Products: Product, Offer
  • Companies: Organization, LocalBusiness
  • People: Person, Author

2. Define Properties

Define the relevant properties for your schema type:

Property
Description
Required
@type
Schema type
Yes
name
Name of the entity
Usually yes
description
Description
No
url
Page URL
No
image
Image URL
No

3. Create JSON-LD Code

Create the JSON-LD code with all required properties:

{
  "@context": "https://schema.org",
  "@type": "Product",
  "name": "SEO Handbook 2025",
  "description": "Comprehensive handbook for search engine optimization",
  "brand": {
    "@type": "Brand",
    "name": "SEO Publisher"
  },
  "offers": {
    "@type": "Offer",
    "price": "29.99",
    "priceCurrency": "EUR",
    "availability": "https://schema.org/InStock"
  }
}

4. Embed Code

Add the JSON-LD code to the <head> of your HTML page:

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Article",
  "headline": "Article Title",
  "author": {
    "@type": "Person",
    "name": "Author Name"
  }
}
</script>

Testing and Validation

Google Rich Results Test

Use the Google Rich Results Test to verify your structured data:

  1. URL Test: Enter your page URL
  2. Code Test: Insert the JSON-LD code directly
  3. Check Result: Review errors and warnings

Google Search Console

Monitor your structured data in Google Search Console:

  • Rich Results Report: Shows all detected structured data
  • Error Tracking: Automatically identifies issues
  • Performance Tracking: Measures the performance of your Rich Results

Avoiding Common Mistakes

1. Wrong Schema Types

  • Use the appropriate schema type for your content
  • Avoid generic types like "Thing"
  • Check the Schema.org documentation

2. Missing Required Fields

  • Implement all required properties
  • Use valid data types
  • Validate regularly

3. Duplicate Content

  • Avoid duplicate structured data
  • Use canonical tags for similar content
  • Consolidate related schemas

4. Incorrect Data

  • Ensure data is correct
  • Update outdated information
  • Synchronize with visible content

Best Practices for Structured Data

1. Quality over Quantity

  • Implement only relevant schemas
  • Focus on important pages
  • Avoid schema spam

2. Regular Maintenance

  • Monitor errors in GSC
  • Update outdated data
  • Test changes before going live

3. Consider Performance

  • Minimize JSON-LD size
  • Avoid unnecessary nesting
  • Optimize for fast loading times

4. Mobile Optimization

  • Ensure schemas work on all devices
  • Test on different screen sizes
  • Consider mobile-specific properties

Monitoring and Optimization

KPIs for Structured Data

Monitor these important metrics:

KPI

A/B Testing for Rich Results

Test different schema implementations:

  1. Different Schema Types: Compare various approaches
  2. Property Variations: Test different properties
  3. Placement: Experiment with code position
  4. Performance Impact: Measure effects on loading time
