There are 2 types of feedback on Amazon:
Seller feedback and product feedback/reviews.
Seller Feedback: Seller feedback is more important for FBM sellers – customers will rate your service as a seller (communication, time to ship, if the item is as described, etc.).
Product Feedback/Reviews: Product feedback/reviews are extremely crucial for the health and sales of your listing. Product feedback/reviews are indicated by a number of stars out of 5 on your listings.
