Using your case study, what's that high level thinking that you use from the beginning all the way to the end result of a campaign?

Really my question is wrapped around the case study that you used in the direct presentation that you used to get us into this class where day one was the $1.80 ad spend and then eventually you showed the 30 days in May where you spent about $3.50 and generated $600,000 in sales. So I guess really, I'd love to have a walkthrough of the 30,000 foot view of, you start day one at a $1.88, you get three days worth of data. Day three to six, day six to nine. What's that high level thinking that you use from the beginning all the way to the end result of that campaign? That was unbelievable...
