Hi, I'm Jon Dykstra, publisher of Fat Stacks and several other profitable niche sites.
I've been publishing niche sites full time since 2012. Until recently, most of my 1 million+ monthly visitors came from Google search. Actually that's still the case, but traffic is growing leaps and bounds thanks to Pinterest.
And no, the traffic stats above do not pertain to Fat Stacks. It's another niche site I own and publish.
