How to Add Product Schema in Shopify

Shopify product schema should describe the product a shopper can actually buy: name, image, description, brand, price, currency, availability, URL, and review signals when they are real and visible.

The tricky part is that Shopify themes, SEO apps, review apps, and variant apps can all output JSON-LD. Before adding more markup, audit what already exists.

1. Audit existing Shopify schema first

2. Where to add Product schema in Shopify

In most Shopify themes, Product JSON-LD belongs in a product template or product section that has access to the product Liquid object. The exact file depends on your theme architecture, but common places include product JSON templates, main-product sections, or snippets included only on product pages.

3. Basic Shopify Product JSON-LD

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Product",
  "name": {{ product.title | json }},
  "description": {{ product.description | strip_html | json }},
  "image": [
    {% for image in product.images limit: 6 %}
      {{ image | image_url: width: 1200 | prepend: "https:" | json }}{% unless forloop.last %},{% endunless %}
    {% endfor %}
  ],
  "brand": {
    "@type": "Brand",
    "name": {{ product.vendor | json }}
  },
  "sku": {{ product.selected_or_first_available_variant.sku | json }},
  "offers": {
    "@type": "Offer",
    "url": {{ shop.url | append: product.url | json }},
    "priceCurrency": {{ cart.currency.iso_code | json }},
    "price": {{ product.selected_or_first_available_variant.price | divided_by: 100.0 | json }},
    "availability": "https://schema.org/{% if product.available %}InStock{% else %}OutOfStock{% endif %}",
    "itemCondition": "https://schema.org/NewCondition"
  }
}
</script>

4. Handle variants carefully

Shopify products often have variants for size, color, material, quantity, or subscription. If variants change price or availability, your schema should not claim one generic offer that contradicts the selected or canonical variant.

5. Shopify Markets, currency, and hreflang

If you use Shopify Markets, the same product may render different currencies, URLs, availability, and localized content. Product schema should match the market-specific page that the crawler and shopper see.

6. Add review schema only when reviews are real and visible

Review apps may output AggregateRating and Review markup. Do not manually invent review schema if the review content is not visible or if the app already outputs it. Duplicate review markup can create conflicts.

7. Add BreadcrumbList for product context

Breadcrumb schema helps explain product hierarchy. In Shopify, products can appear in multiple collections, so choose a stable breadcrumb strategy that matches the visible page rather than switching unpredictably.

8. Validate after theme and app changes
