STRUCTURED DATA
Product & Offer Schema Generator
Product markup lets search engines show price, availability and ratings under a product page, and feeds Google’s merchant listings. Most stores generate it from a plugin; this builds it by hand for one product, or shows what correct markup looks like.

HOW IT WORKS
How to use the Product & Offer Schema Generator
Product name, images, identifiers, brand, price, currency, availability and (optionally) real ratings.
Enter the product details and the price exactly as the page shows it.
Add a GTIN if the product has a barcode.
Copy the markup and compare it with your plugin’s output.
WHAT IT CHECKS
What it looks at, and how to read it.
Validated Product JSON-LD for product snippets and merchant listings.
What it checks
- Name, image, price and currency
- GTIN length
- Availability and condition values
- Ratings only with a review count
How to read the results
- The price must match the visible price on the page, in the same currency.
- Ratings are included only when both the average and the count are filled in.

GOOD TO KNOW
Common mistakes, an example and the limits.
Common mistakes
- A price in the markup that differs from the page after a sale.
- Ratings copied from another site.
- Leaving out the currency (KES).
A worked example
A phone listed at KSh 24,999, in stock, new, with 38 reviews averaging 4.6: the generator adds an Offer and an AggregateRating.
Limitations
- Builds markup from what you enter; it cannot check that the page shows the same information, which Google requires.
- Valid markup makes a page eligible for a rich result. Google decides whether to show one.
FAQ
Questions about the Product & Offer Schema Generator
Straight answers about what it does and where its limits are.
Do I need a GTIN?
Google recommends one when the product has it; it helps match your product with others. Own-brand products may not have one.
Can I add ratings from my store’s reviews?
Yes, when they are shown on the product page. Ratings for the store itself belong elsewhere.
