A product feed or product data feed is a file made up of a list of products and attributes of those products organized so that each product can be displayed, advertised or compared in a unique way.[1] A product feed typically contains a product image, title, product identifier, marketing copy, and product attributes.[2] But, can also contain links to rich media assets such as videos, 3D animations, brochures, product stories, product relations, and reviews, as in the case of Open Icecat, the multilingual open content catalogue.
Product feeds supply the content that is presented on many kinds of e-commerce websites such as webshops, search engines, price comparison websites, affiliate networks, and other similar aggregators of e-commerce information. Product data feeds are[3] generated by manufacturers, online retailers and, in some cases, product information is extracted using web scraping or harvested web harvesting from the online shops website.
