Just want to share my first week in CPA world now, last week I started with 7search - peerfly (email&zipcode submit).
As per today, I earn around $120 . Campaign cost was $70, (including my testing here and there), so it makes $50 net in profit or 70% ROI.
I think 100% ROI is very possible.
Problem for me is it can'be scaled up, maximum profit can be achieved maybe around $200-$300 a month.
(that's already for running multiple campaign/offers, in my case I run 6-8 campaigns at the same time)
So, my plan is to scale it, using other PPC platform, or maybe PPV.
My target is to getting $5000/month. I'm ready to invest more and learn more.
Any suggestion is welcome, thanks.
