What is Product JSON-LD used for?

Product JSON-LD tells search engines the structured details of an item you sell. Google can then show price, availability and star ratings directly in search results, which improves click-through rates.

Which availability values are valid?

Schema.org expects a URL value such as https://schema.org/InStock, OutOfStock, PreOrder or BackOrder. This tool outputs the full URL form so it always validates.

Do I need an aggregateRating to qualify for rich results?

No. Price and availability alone can produce offer rich results. Ratings are optional but they add review stars, so include them only when you have genuine review data.

Where should I place the script tag?

Anywhere in the HTML works, but the head is conventional. Place exactly one Product block per product page so Google does not see conflicting data.

Will fake review counts get me penalised?

Yes. Google requires ratings to reflect real user reviews visible on the page. Inventing numbers risks a structured-data manual action, so only output ratings you can back up.

Product structured data in one paste

The JSON-LD Product Schema Builder turns a handful of product fields into a valid schema.org/Product block. Search engines read this markup to display price, stock status and star ratings beside your listing, which is one of the cheapest ways to lift click-through rate on commercial pages.

How it works

The tool assembles a JSON object with @context set to https://schema.org and @type set to Product. Your name, description, image, brand and SKU become top-level properties. Price, currency and availability are nested inside an offers object of type Offer, and the availability is emitted as a full schema.org URL (for example https://schema.org/InStock) because Google requires the URL form. If you supply a rating, an aggregateRating object is added with ratingValue, reviewCount and a bestRating of 5. Empty fields are omitted so the output stays clean and valid.

Tips and example

Always use an absolute, crawlable image URL — relative paths fail validation. Use an ISO 4217 currency code such as USD, EUR or GBP. After copying, run the markup through Google’s Rich Results Test to confirm there are no errors before you ship.
