Information about participants in an auction are received and analyzed along with information about products to be auctioned and other information to generate an interest gauge. The interest gauge may reflect the interest of a buyer, a seller, an auction house or any other entity in the auctioning event. Based on the interest gauge, the operations of the auction can be augmented and/or modified to be optimal in view of revenue generation, products moved, and a balance between the two. For instance, the buyer interest gauge could be used to create packages of items to be auctioned in a combinatorial auction.
