Practical Ecommerce, 1/14/14
Online marketplaces bring buyers and sellers together to exchange goods and services. Social media encourages marketplace mentality by enabling product discovery in a social environment, where prospective customers can rely on the influence of friends to help them shop.
Shoppers can tell the world whether they Like a merchant or a product. In turn, merchants can share details of themselves such as their names, faces, outside interests, and provide easy methods for consumers to communicate with them.
