JSON-LD Implementation

JSON-LD (JavaScript Object Notation for Linked Data) is the recommended method for implementing Structured Data. It is easy to implement and maintain.

Example: Product Schema with JSON-LD

{
  "@context": "https://schema.org",
  "@type": "Product",
  "name": "iPhone 15 Pro",
  "description": "The latest iPhone with A17 Pro chip and titanium design",
  "image": "https://example.com/images/iphone15pro.jpg",
  "brand": {
    "@type": "Brand",
    "name": "Apple"
  },
  "sku": "IPH15PRO-256",
  "offers": {
    "@type": "Offer",
    "price": "1199.00",
    "priceCurrency": "EUR",
    "availability": "https://schema.org/InStock",
    "seller": {
      "@type": "Organization",
      "name": "TechStore GmbH"
    }
  },
  "aggregateRating": {
    "@type": "AggregateRating",
    "ratingValue": "4.8",
    "reviewCount": "127"
  }
}

    "@type": "Question",
    "name": "What warranty does the product have?",
    "acceptedAnswer": {
      "@type": "Answer",
      "text": "All products have a 2-year manufacturer warranty."
    }
  }]
}
