Abstract: In an example embodiment, a method is provided for providing a profile of a seller. In this method, a request from a computing device inquiring about the profile of the seller of an item is received. A category and/or price of the item are identified. Information from transactions associated with the seller is retrieved from a data structure using the category and/or prices as the filtering criteria. A metric is then calculated based on the information from the previous transactions and thereafter, a response to the request with the metric is provided to the computing device.
