Create valid Product JSON-LD structured data for your online shop — with price, availability, GTIN and ratings, ready for Google Merchant listings. Instant, in your browser, free.
Basic info
Identifiers
The GTIN (barcode number, EAN/UPC) is optional but strongly recommended — Google uses it to match your product for Merchant listings.
Price & availability
Ratings (optional)
Optional. Add both a rating and a review count to include an aggregateRating — the markup that can show star ratings in search results.
JSON-LD code
Fill in the required fields (name, price, currency) to generate the JSON-LD code.
Why Product schema matters for Merchant listings
Product structured data tells Google exactly what you are selling: the name, image, brand, price, availability and condition of an item. When this data is present and valid, your pages become eligible for rich product results and free Merchant listings in Google Search, Google Images and the Shopping tab — often shown with price, availability and star ratings directly in the results. That extra detail makes your listing stand out and typically improves click-through. Without valid Product markup, Google has to guess this information from the page, and your products are far less likely to appear in these enhanced placements.
Required fields for Google Shopping
At a minimum, Google needs a product name and an offer with a price and currency — those are the fields this tool requires before it outputs code. To actually qualify for Merchant listings and rich results, you should also provide an image, a brand, and a unique product identifier: a GTIN (the barcode/EAN/UPC number) and/or an SKU. The GTIN is the single most valuable identifier because Google uses it to match your exact product across the web. Availability and item condition round out the offer, and an aggregateRating (rating value plus review count) unlocks star ratings — but only mark up ratings that are genuinely visible on the page.
How to add the schema to your shop
Copy the generated code and paste it into a script tag of type application/ld+json in the head section of the product page it describes. Most shop systems let you add this in a theme template or via an SEO app; the name, price and availability in the markup must match what customers actually see on the page. A minimal example looks like this:
<script type="application/ld+json">
{
"@context": "https://schema.org",
"@type": "Product",
"name": "Executive Anvil",
"brand": {
"@type": "Brand",
"name": "ACME"
},
"offers": {
"@type": "Offer",
"price": "119.99",
"priceCurrency": "EUR",
"availability": "https://schema.org/InStock"
}
}
</script>Frequently asked questions
- Which fields are required for Product schema?
- Schema.org and Google need at least a product name and an offer with a price and price currency. This tool enforces exactly those three. For Merchant listings and rich results, also add an image, brand and a GTIN or SKU.
- What is a GTIN and do I need one?
- A GTIN is the global trade item number encoded in a product's barcode — usually an EAN (13 digits) or UPC (12 digits). It is optional in schema.org terms but strongly recommended, because Google uses it to identify your exact product and is far more likely to show it in Merchant listings.
- Can I show star ratings in Google results?
- Yes, if you add an aggregateRating with a rating value and a review count. Google can then display star ratings in the search snippet. Only mark up ratings that are actually shown to users on the page, otherwise it violates Google's guidelines.
- Does this tool store my product data?
- No. The generator runs entirely in your browser. Nothing you type is sent to a server, stored, or tied to an account — you just copy the generated JSON-LD and paste it into your shop.
- How do I check that the markup is valid?
- Paste your product URL or the generated code into Google's Rich Results Test or the schema.org validator. They parse the JSON-LD and report whether the Product and Offer structure is valid and eligible for rich results.
