Also, monitor negative reviews (3 stars or lower). See how your product ranks for specific keywords. Quickly respond to any 3 star or less Negative Reviews. The vast majority of Amazon customers will leave a positive review. However, there’s no 5-star review guarantee. Should you get a negative review, make sure you quickly respond to any negative feedback from your products. If you address the problem in short order, Amazon customers are usually pretty good about removing unfavorable comments.
