Product pages include schema.org markup

Google and Bing use schema.org Product and Offer structured data to populate rich results — price, availability, and review stars displayed directly in search results. Without application/ld+json markup on product pages, listings appear as plain blue links competing against structured cards from competitors. For Google Shopping specifically, the schema.org Offer.availability field controls whether a product appears in shopping results at all. The schema-org Offer spec also feeds into AI shopping assistants that extract product data for recommendations — pages without structured data are invisible to this emerging discovery channel.

Add a <script type="application/ld+json"> block to src/app/products/[slug]/page.tsx with at minimum the Product and Offer types, including dynamic availability from stock state.

<script
  type="application/ld+json"
  dangerouslySetInnerHTML={{
    __html: JSON.stringify({
      '@context': 'https://schema.org',
      '@type': 'Product',
      name: product.name,
      description: product.description,
      image: product.images,
      sku: product.sku,
      offers: {
        '@type': 'Offer',
        price: product.price.toString(),
        priceCurrency: 'USD',
        availability:
          product.stock > 0
            ? 'https://schema.org/InStock'
            : 'https://schema.org/OutOfStock',
      },
    }),
  }}
/>

Validate output with Google's Rich Results Test after deployment — structured data syntax errors are silent at render time.
