JSON-LD vs Microdata

Comparing the two main formats for implementing structured data on websites.

JSON-LD

JavaScript Object Notation for Linked Data - structured data in a script tag, separate from HTML.

Advantages

  • Recommended by Google
  • Easier to implement and maintain
  • Doesn't affect page rendering
  • Can be injected dynamically

Considerations

  • Requires JavaScript knowledge
  • Potential for errors if not validated
  • Less visible in page source
  • Can be outdated if page content changes

Microdata

Structured data embedded directly in HTML elements using attributes like itemscope and itemprop.

Advantages

  • Visible in HTML structure
  • Tightly coupled with content
  • No separate script needed
  • Changes with content automatically

Considerations

  • More complex to implement
  • Harder to maintain
  • Can clutter HTML
  • Mixing content and metadata

Our Verdict

JSON-LD is the modern standard. It's easier to implement, maintain, and validate. Use JSON-LD unless you have specific requirements for Microdata.
