Question: What do the stars after member feedback scores mean?
The colorful stars that appear after feedback scores are a fixture on eBay, but many members never take the time to learn what they mean.
Answer:
The stars that follow a member's feedback score in parentheses are a visual representation of that member's accumulation of positive eBay experience. They are color-coded to indicate the amount of successful trading that an eBay members has done.
Members new to eBay do not have a star, since the first star is granted at a feedback score of ten (10). Members with exceedingly high feedback scores receive "shooting stars," which often indicate a member who sells on eBay as his or her primary source of income.
More information on stars and the colors that are associated with various feedback scores can be found on eBay's feedback star glossary.
