A fairly ok treatment of the whole "come up with a niche // affiliate offer // lead magnet // landing page // autoresponder emails... process."
The highlighted traffic source is instagram. And the whole idea of getting followers and more engagement with them....
OK for some. I'm sure someone does make money that way. If you love instagram, this might just be your ticket.
I believe in creating offer funnels that lead into each other which result in such an overwhelming payoff per initial click that you can afford to pay $3 or even more a click. And usually you don't have to pay more than 10 - 20 cents. But this requires a reasonable amount of testing. And more than the normal amount of patience and determination.
But then, you never have to worry about availability of traffic or scalability issues.
