DSR’s are the Detailed Seller Ratings, or the star ratings system appointed to each seller. In addition to leaving positive, negative, or neutral feedback for a transaction, they’ll also have the opportunity to rate you on shipping costs, item as described, fairness of shipping costs, and communication with the buyer. Ebay now uses the DSR ratings to promote certain sellers on the Ebay site. If you have stellar DSR ratings, you could wind up having more clout in the Ebay search than sellers who do not have a good DSR ratings. Like feedback, honesty is key to getting good DSR ratings. The other major factor is the cost of shipping and the speed of delivery. Shipping the item out as quickly as possible and offering free shipping are good ways to boost your DSR ratings.
