There are two kinds of auction sites: business-to-person and person-to-person. In the former, it is the Web site that has possession of the goods on sale and accepts payment for them, whereas a person-to-person auction site merely provides a means by which sellers can sell their goods directly to customers.

举办拍卖的网站有两种：商品对人的交易及人对人的交易。前者，网站拥有待价而沽的物品并收取拍卖所得；后者则只提供卖方直接销售物品给顾客的途径。
