Reviews are a huge part of the online shopping experience. For many potential buyers, they are the difference between making a purchase or not. Unlike a brick and mortar store, shoppers cannot have any contact with the items before buying them. They also know that returns tend to be a bit more complicated. As a result, they rely on the knowledge of those who have already bought the products they’re interested in. They look into the reviews to make a decision before ordering, and just a few five-star reviews can sell them entirely on a product -- just as a few negative reviews can make them look elsewhere.
