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.

What is the JSON-LD Product Schema Builder?

Generate valid Product JSON-LD structured data with name, description, image, brand, offers (price, currency, availability) and aggregate rating. Paste it into any page to earn product rich results in Google Search. It runs free in your browser on Gera Tools, with nothing uploaded.

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.

"offers": {
  "@type": "Offer",
  "price": "29.99",
  "priceCurrency": "USD",
  "availability": "https://schema.org/InStock"
}

When product rich results show up in search

Google can display price, availability, and rating stars alongside your organic search result when the page carries valid Product JSON-LD. This enriched result — sometimes called a “product snippet” — appears in regular search results, Google Shopping, and the Images tab. The practical effect is that your listing occupies more visual space and signals key purchase signals before the user even clicks.

Rich results eligibility requires:

A crawlable product page (not login-gated)
A visible price and availability on the page that matches the markup
If you include aggregateRating, those stars must reflect real user reviews that are also visible on the page

Availability values and what they mean

The availability property must be a full schema.org URL. The most common values:

URL	Meaning
`https://schema.org/InStock`	Ready to ship now
`https://schema.org/OutOfStock`	Currently unavailable
`https://schema.org/PreOrder`	Not yet released, can order in advance
`https://schema.org/BackOrder`	Sold out but re-order is accepted
`https://schema.org/Discontinued`	No longer sold

Keeping this field accurate is important. Outdated or incorrect availability data can lead Google to suppress the rich result or, in repeated cases, to trigger a manual review of the structured data.

Ratings — when to include them and when not to

The aggregateRating block adds star icons to your search result, which typically increases click-through rate. However, including this block when you do not have real reviews on the page violates Google’s structured data quality guidelines and can trigger a manual action that removes all rich results from your site.

The safe rule: only add aggregateRating when:

Real user reviews are visible to anyone who visits the page.
The ratingValue and reviewCount in the schema match what the page actually shows.

Importing 200 reviews from a third-party platform and displaying them on the page is fine. Hardcoding a reviewCount of 500 without actual reviews is not.
