Check if the reviewer is legitimate. About eight out of ten consumers believe that they may have read a fake review last year, and the same number indicates that they aren't sure if they know how to spot a fake review. While there are many customers who use and review the products for free immediately after their release date, this is far from normal. Another common type of false criticism is that of a “professional reviewer,” that is, someone who was given the product for free and gave extra money to give a five-star review, Paldan says.
Most fake critics won't respond, but real critics often look forward to opportunities to help more, Lai says.
