JSON-LD is a lightweight, structured data format that helps Google search engines better understand, categorize, and interpret website content accurately.
What is JSON-LD?
JSON-LD (JavaScript Object Notation for Linked Data) is a method of encoding structured data in JSON format. It’s primarily used for implementing schema markup, which allows search engines like Google to comprehend the context of your content — such as reviews, events, products, and more.
Unlike Microdata or RDFa (which are embedded inline), JSON-LD is placed inside a <script type="application/ld+json"> tag — keeping your HTML cleaner and easier to maintain.
How to Use JSON-LD
- Identify what content you want to mark up (e.g., article, product, review).
- Go to Schema.org and find the correct schema type.
- Create the JSON-LD script with proper properties and values.
- Place the script in the
<head>or just before the</body>tag of your HTML.
Benefits of JSON-LD for SEO
- Improves search engine understanding of page content
- Increases chances of rich results (stars, FAQs, product info, etc.)
- Easier to maintain than inline microdata
- Cleaner HTML code structure
- Supports advanced SERP features like Knowledge Graph and Featured Snippets
