What is JSON-LD?
JSON-LD (JavaScript Object Notation for Linked Data) is Google's recommended format for adding structured data markup to web pages. It helps search engines understand page content and enables rich results like star ratings, FAQ dropdowns, and event listings in search results.
JSON-LD is the most popular structured data format because it's clean, easy to implement, and doesn't interfere with your page HTML.
1
How JSON-LD works
JSON-LD is added as a <script> tag in your page's HTML, separate from the visible content. It uses Schema.org vocabulary to describe entities on your page.
Because it's separate from the DOM, JSON-LD doesn't affect page layout or performance. Google can read it during crawling to understand what your page is about.

Rich results from JSON-LD
JSON-LD can enable rich results like:
• FAQ dropdowns - Expandable Q&A in search results
• Star ratings - Review stars on product/service listings
• How-to steps - Step-by-step instructions
• Event details - Date, time, location, ticket info
• Local business info - Hours, address, phone
• Article info - Author, date, publisher
• Breadcrumbs - Navigation path in results
• Sitelinks search - Search box in results
Rich results increase click-through rates by 20-30% on average.
