What is JSON-LD?
JSON-LD Format
JSON-LD (JavaScript Object Notation for Linking Data) is a structured data format that makes it easy to add Schema.org markup to your website. Unlike Microdata, JSON-LD keeps your HTML clean while providing rich semantic information to search engines.
Why Use JSON-LD?
- ✓Clean HTML - no inline markup needed
- ✓Easy to implement and maintain
- ✓Full Schema.org vocabulary support
- ✓Rich Results eligibility
