Inside this folder, create:

product-schema.php – Main plugin file
schema-functions.php – Functions to generate schema
admin-settings.php – Admin settings panel

2. Implement JSON-LD Schema for Products

Use JSON-LD format to generate product schema dynamically.

Example JSON-LD Schema Markup for Products

{
  "@context": "https://schema.org/",
  "@type": "Product",
  "name": "Smartphone XYZ",
  "image": "https://example.com/product.jpg",
  "description": "Latest model with high-speed performance.",
  "brand": {
    "@type": "Brand",
    "name": "TechBrand"
  },
  "sku": "XYZ123",
  "offers": {
    "@type": "Offer",
    "priceCurrency": "USD",
    "price": "499.99",
    "availability": "https://schema.org/InStock",
    "url": "https://example.com/product"
  },
  "aggregateRating": {
    "@type": "AggregateRating",
    "ratingValue": "4.7",
    "reviewCount": "150"
  }
}

3. Fetch WooCommerce Product Data

Use WooCommerce hooks to dynamically fetch product data.

$product = wc_get_product( get_the_ID() );
$schema_data = array(
    '@context'    => 'https://schema.org/',
    '@type'       => 'Product',
    'name'        => $product->get_name(),
    'image'       => wp_get_attachment_url( $product->get_image_id() ),
    'description' => wp_strip_all_tags( $product->get_description() ),
    'sku'         => $product->get_sku(),
    'offers'      => array(
        '@type'         => 'Offer',
        'priceCurrency' => get_woocommerce_currency(),
        'price'         => $product->get_price(),
        'availability'  => $product->is_in_stock() ? "https://schema.org/InStock" : "https://schema.org/OutOfStock",
        'url'           => get_permalink($product->get_id())
    )
);
