In an adult market, does the correlation of traffic to sales generally occur across the board? I know blogs convert differently than TGP's or LL, but have you guys experienced a correlation?
Let's say you submit to TGP's and recieve 500k visitors to your galleries a day and you make 5 sales a day consistently off that, would it be safe to say that 1 mil visitors equate to 10 sales? And likewise with a blog, let's say you recieve 1500 visitors a day and make 2 sales consistently, would it also be safe to say that with 3000 visitors a day you make 4 sales?
I know there are too many variables with niches, bookmarked, or unique ect, I'm just asking in a VERY general sense.
Is traffic really king?

Or is my thinking too simplisitc in this particular market?
