On the other hand, you might be right on target but just need to give potential bidders a bit of a nudge to get them started. Remember, auction behavior is not always rational.
Bids attract more bids.
An auction can sit idle day after day, then once one bid is posted others come in and the auction comes to life. To diagnose your situation, first add counters to your auction pages. You can do that quickly and for free from AuctionRover's Auction Manager. If you are getting lots of visits but no bids at all, the odds are good that your initial price is too high or your description confusing. Then if the auction ends with No Sale, restart with a lower price or, if you have a number of similar items, start a new auction that combines several items into a single lot, with the same starting price you previously had for one of them.
