Product Reviews

In electronic commerce, product reviews are used on shopping sites to give customers an opportunity to rate and comment on products they have purchased, right on the product page. Other consumers can read these when making a purchase decision. Often, the company will include a URL on printed literature or e-mail marketing to invite customers to review their service after a transaction has been completed.
