Product JSON-LD Checker

The block does not parse. The usual causes are a trailing comma, a smart quote pasted in from a document, or an unescaped quote inside a product name.

Fix: Fix the syntax; the parser error says where it gave up.

Source: Derived from JSON syntax itself.

The @type is missing or is not Product, so none of the product rules apply to it.

Fix: Set "@type": "Product".

Without "@context": "https://schema.org" the vocabulary is undefined, and the block is ignored no matter how correct the rest of it is.

Fix: Add "@context": "https://schema.org".

name is required on Product. Everything else describes something that is not identified.

Google requires at least one of offers, review and aggregateRating. A Product with none of them carries no information a rich result could show, so nothing appears — which looks identical to markup that was never added.

Fix: Add offers with a price, which is the one most product pages can supply honestly.

price must be a number. A currency symbol, a thousands separator or a comma decimal separator makes it a string that cannot be read as an amount — and "19,99" is the worst of them, because it looks right to a European reader and parses as something else or as nothing.

Fix: Write the bare number with a full stop: 19.99, and put the currency in priceCurrency.

An offer without a price is an offer of nothing. Google requires price or priceSpecification.price.

The currency must be the three-letter ISO 4217 code — USD, not $ and not "dollars". A symbol is ambiguous in any case: $ is used by more than twenty currencies.

Fix: Use the three-letter code.

Most currencies use two decimal places, but JPY and KRW use none and BHD and KWD use three. A price whose decimals do not match its currency is usually a sign the amount was converted or scaled somewhere upstream.

The gtin fails validation — a wrong check digit, a restricted range, or a known placeholder. Structured data with a broken identifier is worse than none: it asserts, in machine-readable form, that this product is one that does not exist.

Fix: Validate the barcode before publishing the markup.

Source: Google Search Central — Product snippet structured data

The gtin passes validation but the barcode engine flagged something about it — a restricted in-store range, a known placeholder, or a publication number. Structured data states this identifier to machines, so a caveat that would be tolerable in a spreadsheet is worth reading here.

Fix: Open the full validation to see what was flagged.

availability takes a schema.org URL such as https://schema.org/InStock. Free text like "in stock" or "yes" is not recognised and is dropped.

Fix: Use https://schema.org/InStock, OutOfStock, PreOrder or BackOrder.

A relative image path resolves against whatever page happens to embed the markup, which is not necessarily the page you tested it on.

Fix: Use the full URL including scheme and host.

Source: Derived from how a crawler resolves the value, which has no page context of its own.

A rating asserted with a review count of zero — or with no count at all — is a rating nobody gave. Fabricated ratings are a documented cause of manual action, and the markup is machine-readable evidence.

Fix: Only publish an aggregateRating you can substantiate from real reviews.
