Before you start: the one decision you have to make
Before starting the integration, you must decide which schema mode your product page needs —
which depends on one question, below: does your page already publish Product structured data?
This decision is a mandatory first step and must not be skipped: the wrong mode leaves the product's ratings with no chance of appearing on Google.
Please make sure this decision is taken before proceeding with the technical integration.
Does your product page already publish Product structured data of its own?
Most e-commerce platforms do — Shopify, WooCommerce, PrestaShop and Magento SEO modules usually emit it. Check before assuming:
- Open your product page.
- View source (
Ctrl+U) and search forapplication/ld+json. - Look for
"@type": "Product"inside those blocks.
Your answer decides which mode you use, and the two are not interchangeable:
| Your page… | Use | You must provide |
|---|---|---|
already emits Product | schema=rating-only | the @id of your existing Product node |
does not emit Product | schema=full | nothing — but pass your product name if you have it |
Why it matters: two Product nodes for one page is ambiguous markup and search engines may
ignore both. A rating with no product attached is an orphan node they ignore outright.
schema=full works with just the EAN. Google requires a name on a Product, and when you do
not pass one the service uses the product name from Shopadvizor's catalogue.
Pass your own name whenever you can. Yours always wins, and it is the better value: Google
expects the structured data to match what the page actually displays, and the catalogue name may be
worded differently from your product title. Treat the fallback as the floor, not the target.
schema=rating-only is different — there is nothing to fall back to. The @id of your Product
node is something only your page can supply.
If neither mode fits, there is a third option:
schema=none, where you write the structured data yourself.
