What are Product feeds sites, and how there are productive for a e-commerce site?

A product feed is a file containing information about the products listed on your site. Product feeds are used by e-commerce companies to provide information about products in an online store to search engines, product comparison websites, and other similar aggregators of e-commerce information. By sending product feeds regularly you can make sure these sites display the latest pricing, promotional, or other information for your products.
