<!-- Page Without Schema -->
<head>
  <title>Product Name</title>
  <meta name="description" content="Product description...">
  <!-- No schema markup! -->
</head>

<!-- Page With Schema -->
<head>
  <title>Product Name</title>
  <meta name="description" content="Product description...">
  <script type="application/ld+json">
  {
    "@context": "https://schema.org",
    "@type": "Product",
    "name": "Product Name",
    "description": "Product description...",
    "brand": {
      "@type": "Brand",
      "name": "Brand Name"
    },
    "offers": {
