When first looking at the sales page, no one cares about the product. They only care about what people have said about products. After potential customers see numerous good reviews, then they start to buy in on the idea (and the product).
Testimonials act as proof that your product is elite. You don’t want people to guess about how good your product is. Amazon does not let people guess. All of their products can be reviewed based on a 1 to 5 star scale. The products with more 5 star are the products that get more sales. A lot of 5 star reviews reveals that the product is a must-have.
A description will not be enough to get people to buy your product. It is helpful, but in the end, the description is written by someone who wants you to buy their product. That’s where the testimonials come in. Real customers say what they like about the product, and that encourages potential customers to buy the product.
The products with the most sales are the ones with the most testimonials. Testimonials (also known as reviews on Amazon and many other places) tell people that what you have is extraordinary.
