Is a product scheme on the category page sufficient?

No. Rich results are created per product page. The category page has an ItemList with references to the products, each product page has its own product with offer.

Our shop uses Microdata instead of JSON-LD. Does that count?

The test area reads JSON-LD because Google recommends it and because it can be maintained without intervention in the layout. Microdata still works on Google, but is not evaluated here; The switch is usually a switch in the shop system.

What happens to the point value?

Until the release of seo-v6 nothing: the result is in the file and task list, the point value follows seo-v5. With seo-v6, a missing product scheme on shop pages weighs six points, an incomplete four.

Product scheme: what a product page needs to say to Google and Merchant Center

A product page carries its facts for people in the layout and for machines in the JSON-LD: name, image, price, currency, availability. Google builds the product rich results in the hit list, Merchant Center compares the offers. Since seo-v6, the SEO test area recognizes the page type and checks whether a product scheme is there and whether it is complete on pages of the shop type. The findings are in the file and in the task list; It costs points only when the operator releases seo-v6.

What exactly is checked

The kernel reads every JSON-LD block of the page, also nested in @graph, mainEntity, itemListElement and hasVariant. If he finds neither a product (also ProductGroup, IndividualProduct, ProductModel) nor a product list (ItemList, OfferCatalog) on a shop page, he reports the scheme as missing. If they find a product, they check the fields Google requires for rich results: name, image, offers.price, offers.priceCurrency and offers.availability. If one is missing, the result indicates the product and the missing fields.

Why it matters

The hit list shows price, availability and reviews only from structured data. A shop without a product scheme stands as a blue link next to competitors with prices and stars. Merchant Center checks the offers in the feed against the page; without a scheme, the matching fails or the offer is rejected. And AI response systems read the same fields when they recommend a product.

How the page type is created

The checking area decides for each page from JSON-LD types, purchase buttons, prizes and the path whether it is a shop. The evidence supports the study. A landing page or contribution does not receive this rule; a product list with ItemList is considered a shop with a scheme.

Switch on the module for structured data in the shop system (Shopware, WooCommerce, Shopify, Magento provide product JSON-LD).
Open the source code on a product page and search the block script type=application/ld+json with @type Product; is missing, in the theme or module supplement.
Fill in the fields from the merchandise management system: image as absolute address, price as number, priceCurrency as ISO code (EUR), availability as schema.org value such as https://schema.org/InStock.
Using Google’s Rich Results test, check a product page and process alerts before the next pass measures.
