If you go to an eBay auction and look in the upper right hand corner, you’ll see a section called “Meet the seller.”
The number in parentheses next to the seller’s id (the seller in the example is “incomeeveryday) is the seller’s feedback rating.
After each transaction, the buyer and seller are allowed to rate each other by leaving feedback. Each feedback left consists of a rating (positive, negative, or neutral), and a short comment. These ratings that members leave for each other are used to determine individual member profiles.
To view an eBay member's profile, click on the User ID or the number in parentheses next to their User ID. For example, simply click on "16" to view the profile for incomeeveryday (16). Once the ID or rating is clicked, a new page will appear with a “member profile” section at the top (see image).
Feedback Score
Feedback is a score that represents the number of eBay members that are satisfied doing business with a particular member. It is usually the difference between the number of members who left a positive rating and the number of members who left a negative rating. In the example shown above, the feedback score is 18 - 2 = 16.
Types of Feedback
There are three types of feedback: Positive 
, Neutral 
, and Negative 
.
Positive Feedback
This represents positive ratings left by members as a percentage. In the example shown above, the positive feedback percentage is 16 divided by 16 = 100%.
Members who left a positive
This represents the number of unique members who have given incomeeveryday a positive rating. If a member has had several transactions with incomeeveryday and leaves more than one positive rating, they will still only count once in this number. In the example shown above, 16 unique members have left a positive rating.
Members who left a negative
This represents the number of unique members who have left a negative rating for incomeeveryday. If a member has left multiple negative ratings, they will still count only once in this number.
All positive feedback received
This represents the total number of positive feedback received for all transactions, including repeat customers. In this example, incomeeveryday has received 18 positive ratings.

This table shows all of the ratings left for this member during the past month, 6 months, and 12 months. In the example shown above, incomeeveryday received 0 negative ratings in the past month, 0 in the past 6 months, and 0 in the past one year
