Exit Junction

Exit Junction is relatively new and, I believe, a spin off from the now defunct Revenue Pilot. While Revenue Pilot has stopped running, however, Exit Junction is going from strength to strength. Exit Junction offers a unique approach to advertising that is compatible with all the other Ad Networks included Google Adsense. The key to Exit junction is that they focus on showing ads to users as they leave your site rather than as they arrive or as they browse. This approach offers you an additional way to monetize your traffic and also capture ad revenue from those that stumble upon your site from a search engine and then immediately leave.
By adding a small piece of Exit Junction code to the header section of your site users are shown an advert as they hit the back button. For example, if a user came to your site from a Google search and then immediately hit the back button to return to that search they would be shown an Exit Junction Ad in between your page and the Google search and you get paid for this impression. The ad is directly targeted to the search term that brought the visitor to your site in the first place. Hence Exit Junction is an ideal way of complimenting your existing ad services and so increasing your sites revenue without having to switch from your current ad provider.
Exit junction also covers all countries. You get paid for all traffic exiting you site regardless of its origin.
They offer fee free payout via Check or PayPal with earnings of as little as $25 on a monthly basis.
