As many advantages of online shopping for customers and merchants as there are, there are also disadvantages. These include, for example, not being able to look at the goods in advance, trying them out or trying them on. Customers are therefore dependent on the most meaningful and detailed evaluations possible from other buyers. But this is where there is a lot of potential for fraud. The question often arises as to whether users really bought and tested the item or whether the reviews are fake. This is exactly where Amazon comes in with its addition “verified purchase”.
