    The four core types of schema markup for e-commerce and their relationships

    For e-commerce businesses, schema markup isn't just "nice to have" — it's a direct revenue driver. Correctly implemented structured data can increase your click-through rate by up to 35% and give your products star ratings, prices and availability directly in Google's rich results.

    Webshops with correct Product schema see on average 35% higher CTR and 25% lower bounce rate compared to product pages without structured data — and product data is increasingly read directly by AI shopping assistants.

    Essential schema types for e-commerce

    Product

    The core type for any product. Defines name, description, image, brand and SKU. Without Product schema, Google has no structured understanding of your products.

    Offer

    Nested within Product. Defines price, currency, availability (InStock/OutOfStock) and price validity period. Critical for showing prices in search results.

    AggregateRating

    Aggregates customer ratings into an average score (e.g. 4.5 out of 5 based on 127 reviews). Triggers the coveted stars in search results.

    Review

    Individual customer reviews with author, date and rating. Strengthens credibility and gives Google detailed feedback on product quality.

    How the types connect

    E-commerce schema works as a nested structure where Product is the parent type and the other types are nested within. A typical product page should have this hierarchical structure:

    • Product → defines the product itself with name, description, image and brand
    • Product.offers → one or more Offer objects with price, currency and availability
    • Product.aggregateRating → aggregate rating from all reviews
    • Product.review → individual reviews with author and date

    This structure ensures Google can display Rich Results with all the elements that drive clicks and conversions. Without correct nesting, your data risks being ignored.

    Critical fields you must not forget

    • brand.name — Google uses brand for entity identification. Without it, your products can't be linked to your business.
    • offers.availability — Use schema.org values like InStock, OutOfStock, PreOrder. Google shows availability in results.
    • offers.priceCurrency — Always in ISO 4217 format (DKK, EUR, USD). Errors here prevent price display.
    • image — At least one high-resolution product image. Google prefers 1200×1200 pixels.
    • sku / gtin — Unique product identifiers strengthen knowledge graph integration.
