Formula or logic used

Google Product Structured Data Specification Logic

Google requires specific mandatory and recommended properties under the https://schema.org/Product specification to qualify for product rich results, price drops, and Merchant Listings.

  • Mandatory Base Properties: @context = 'https://schema.org', @type = 'Product', name (string), image (URL or array of URLs)
  • Mandatory Offer Properties: offers (@type: 'Offer', price: numeric string, priceCurrency: 3-letter ISO 4217, availability: https://schema.org/InStock)
  • Identifier Requirements: Google strongly recommends at least one unique product identifier: gtin13, gtin8, gtin14, mpn, or sku to resolve Knowledge Graph entities
  • Rating Logic: aggregateRating (@type: 'AggregateRating', ratingValue: 1-5, reviewCount: integer >= 1) triggers gold review stars in Google SERPs

Frequently asked questions

Why does my product schema need both price and priceCurrency?

Google requires both the numeric price and the standard 3-letter ISO 4217 currency code (such as USD, GBP, or EUR) inside the Offer block to prevent ambiguous pricing displays across international search regions.

Can I use AggregateRating without having individual customer reviews?

Yes. Google allows standalone AggregateRating on Product schema as long as ratingValue, reviewCount (or ratingCount), bestRating, and worstRating are provided and correspond to genuine on-page customer feedback.

Where should I paste the generated JSON-LD on my website?

Paste the `<script type="application/ld+json">` snippet directly inside the `<head>` section or right before the closing `</body>` tag of your product page, or inject it dynamically in Next.js via Metadata or script tags.

What is the difference between SKU and MPN?

SKU (Stock Keeping Unit) is your internal inventory tracking number, whereas MPN (Manufacturer Part Number) is the global identifier assigned by the original manufacturer. Both help search engines disambiguate your product.
