Did you know that Google is experimenting with markup for product data?
Google is experimenting with markup for product data. We do not currently display this information, unless the product is part of a review.
Each product can have a number of different properties, such as name, category, price, and brand. You can use either Microformats or RDFa markup to label these properties.
