Shill bidding policy

Shill bidding is when someone bids on an item to artificially increase its price, desirability, or search standing.

When someone bidding on an item knows the seller, they might have information about the seller's item that other shoppers aren't aware of. This could create an unfair advantage or cause another bidder to pay more than they should. We want to maintain a fair marketplace for all our users, and as such, shill bidding is prohibited on eBay. For more details on what constitutes shill bidding, please see our full policy guidelines below.

How do I report shill bidding?

Policy overview

Shill bidding happens when anyone—including family, friends, roommates, employees, or online connections—bids on an item with the intent to artificially increase its price or desirability. In addition, members cannot bid on or buy items in order to artificially increase a seller's feedback or to improve the item's search standing.

Shill bidding is also illegal in many places and can carry severe penalties.

What are the guidelines?

Not allowed Not allowed
  • Bidding on your own items with another account

Activity on eBay is required to:

  • Follow all applicable laws

If activity doesn't meet these requirements, eBay may take action consistent with applicable laws and the eBay User Agreement, and may even be legally required to do so. Such actions may include, as an example only: administratively ending listings or cancelling transactions, hiding or lowering the placement of listings in search results, lowering seller rating, restricting buying or selling, forfeiture of fees, loss of buyer or seller protections, restricting access to member communication and rating tools, removing feedback, and account suspension.

Why does eBay have this policy?

Shill bidding is unfair to buyers and it's illegal in many places in the world. We have this policy to discourage shill bidding and to make it clear what can happen when people don't follow these guidelines.
