It is a good practice for the E-market places to encourage customers to give their opinion about the service provided by the E-market place or the product bought in the E-market place. This allows potential buyers to check the credibility of the product or the E-market place. Allowing the customers to give their opinion whether it is positive or negative plays an important role in online sales. Reviews are important as the customers wont be able to see and check the products directly. They would like to read the reviews given by other custome
