Product and Offer markup
A JSON-LD script with the product and its offer: name, description, image, brand, SKU, price, currency, availability and page URL.
Create Schema.org markup for a product page.
Fill in name, brand, GTIN, price and availability, and copy ready JSON-LD into your product page. It is generated in your browser, nothing is uploaded.

What the generator creates.
The right GTIN property
The digits go into gtin8, gtin12, gtin13 or gtin14, matched to the code's length. Other lengths use the general gtin property.
Missing essentials
Leave out the name, image, price or brand and you see what to add so search engines can show rich results.
Clean values
A comma in the price becomes a dot, currency codes are capitalized and empty optional fields are left out.
In Central
Structured data from verified facts, for every product.
Central creates product structured data from the verified record for your whole catalog, with the attributes AI assistants and search engines read, not just name and price. Every value traces to a source, and when a fact changes, Central flags every text that uses it.
Instead of pasting markup into each page by hand and hoping the details are still right.

Questions about product markup.
Something else on your mind? Talk to us.
Will this get me rich results?
Markup can make a page eligible, but search engines decide what they show. Fill in name, image, price, availability and brand first.
Where do I put the code?
In the HTML of the product page. Check first that your shop theme does not already add product markup, so the page does not carry two versions.
Does it check whether my data is right?
No. It formats what you enter. Central checks the facts themselves against the brand and independent sources before they go into the markup.
Is my data sent anywhere?
No. The code is generated in your browser.
