Google: Rich Product Info

Rich Product Info is displayed for searches that are directly related to products. This feature displays detailed information about a product, including its price, availability, product reviews, ratings, and a brief description. It can also include images of the product. This rich information is sourced from multiple sites and displayed directly on the SERP, allowing users to compare products at a glance without having to visit individual sites. These rich extensions are discussed on the Google Developer Page!
