As we have mentioned in 'Audience' chapter, reviews is a must-have type of user-generated content in an online shop. This is a word of the crowd that helps your customers make decisions and feel safe knowing that others did the same way. It's called a social proof.
Now let's look at numbers. 70% of potential buyers rely on reviews before making a purchase as PeopleClaim research says. 63% of customers are more likely to buy something in vendor's shop that has reviews, chances are higher if this store has more than six reviews as MarketingProfs says.
