Well, I do not have exact figure, but 1st quarter was pretty good because one of my site ranked #2-#3 on good keywords.  Site used to make around $50 per day then it Jumped to $100 per day from one site.  Organic traffic is just amazing.  After month, I sold site recently..175 % ROI without earning from adsense.  I mean there is no other investment work like this.

Now, my main sites are gone..I am starting working my ass off to next money makers..
