Shill bidding in an online auction occurs when an individual bids on his or her own item (or has an associate bid on the item) in order to artificially raise the price. With the rise in popularity of online auctions, shill bidding has increasingly become an area of concern.
Public perception tends to be anti-shill bidding, with people viewing the practice as unfair at best and illegal at worst.
The outcome of shill bidding is that the people bidding on an item are pushed into paying a higher price through deceptive means. It also can create suspicion and distrust of auction sites.
Shill bidding is basically used to raise the price of an item above its usual market value by creating the illusion of interested bidders competing for the item at the expense of actual bidders. Shill bidding is frequently used on online auction sites, such as eBay, although shill bidding is not limited to online auction senarios. To combat shill bidding, many auction sites have anti-shill bidding policies.
