Yup, that's what I'm DOING too, not only trying. I used the traffic to get more people, soon it will be time for adsense very soon as they all talk along hehehe.
It seems to me that expired domain traffic is competing with your own website traffic. So, at least for targetted traffic, they are taking traffic that you would have gotten and redirecting it to you. Not a good use of marketing money as far as I am concerned.
Are you on herbs? There's no 5 000 plan BTW it's not expired traffic reselling, those are scams. I spoke with the sales guy and he said Quote 'We are partnered with more than 160 000 content oriented web sites, and contract them to deliver traffic to our clients' - Sales Quote (Copy pasted from live chat).
Anyway so far i have received 150 unique visits, but no sales. so 4850 to go. I will update you guys once it ends.
Well, If u need a test drive traffic without any obligation , just see my signature URL. This wont hurt. thanks
