Well for starters, these freebie/GPT sites are doing nothing more than being a middle man for cpa networks. You sign up and complete an offer, freebie/GPT site gives you $30 but they actually got $40 from the cpa network.
So this leads me to wondering why you wouldn't just take out the middle man and rather just use your own cpa links to earn the full commissions. Why give someone a piece of the pie for your the hard work you've done.
With freebie/GPT sites & cpa networks, it only works if someone actually completes an offer(go green). Getting someone to whip out their credit card isn't easy. The email submits are free however, so you can just tell the person who emails you about your auction to submit their email on this page.
About earning good money with this method, I guess this all depends on how much traffic you can really get from an auction. If you said someone got 500K views on their auction, probably not even 1% of them would email the seller if it was stated to do so in the auction. So to break it down, its unlikely your gonna get 500K views. So lets just say you get 100K views(which is still stretching it). And out of 100K views, 1% of them contacts and emails you. Thats 1000 people. Now 100% of those people that email you aren't going to sign up for your GPT site or CPA offer. Maybe 1 out 10 will(10%), so that means 100 people might complete an offer.
I gotta really ask, and I'm skeptical about all these thread titles that say "$1000 a day make it here now!!!", can you really make any money with this method? I mean come on, I can see maybe $50-100 a day if your lucky and fortunate. If I had a method that made $1000 a day I wouldn't tell a soul let alone sell it for less than $10,000.
No pun intended , possibly your just sharing a method for the purpose of it. Thats cool and I like that, but the title is all talk. If this was an unseen method making what it claims, it wouldn't be shared period. I have my own unique methods that make $50 a day for the past 2 years that no one else knows about, completely un-tapped, and I wouldn't share or sell the method in an ebook even if the method no longer worked.
