I am slowly moving more and more into this from my tv sites due to the changes in that niche
I have 18 autoblogs with wp robot
and 10 amazon stores
the ones been going a month are at 40-50 visitors a day the newer ones are 10-15
still optimizing and building links etc
ideally would like 100 autoblogs and 100 amazon stores... and see how much revenue that equates too - then make a decision from there.
I have about 10 of them. Half auto, half quality content. Having quality content vs. auto content seems to make a pretty big difference. My quality blogs have way more visitors compared to my autoblogs.
