Shill Bidding is the term used to describe when you, your employees, family members or someone you know places false bids onto your auctions to increase the end sale price for other bidders. This will force other bidders who really want your item to place a higher bid. You will end up selling the item at very high price.
Shill Bidding not only has never been allowed on eBay, but there can also be severe penalties for anyone caught Shill Bidding. It's illegal to use shill bidding on your auction.
Before starting your auction, make sure you do the market research about the best starting price for your item, whether or not to use reserve price so you won't lose your item too cheap.
All the best :)
