It took me since Sept 2013, I told you that at the beginning..lol
I don't know how much I made per month or anything like that, not something I keep track of...
but you said that you have much more traffic now and from the stats its look like you barely have much before that month, its looked like you barely have traffic before that month and guessed that the traffic that you had in january(very little) was pretty much the same in the last year. if it was the case its quite reasonable to assume that most of the money you made after your site had gained much more traffic.
When you assume something you make an ass out of u and me...lol
You don't know what I did in the last year...
I quit advertising about 6 months back, just started again.
