I offer a web based eBay auction sniping service where I charge 1% of the bids users win but I am thinking of offering free use but that would limit the allowed winnings per month as well as display advertising in their account. Would this be a good idea and if so which PPC advertising program would be the best for this use? The Ads would only show in users accounts using the service for free, the page also refreshes every 15 minutes if that matters. Thank you
I would recommend chitika, http://chitika.com they offers ads for shopping based websites. or http://bidtraffic.com/ they offer high CPC campaigns.
clicksor is useful, they offfer w wide range of ads, in content, popups (if you want..) and unders.. dialog/alert box.. and graphic and text images. good conversions. but beware of making your site looking spammy.. :/ other than google adsense, i chose bidvertizer..
