Greetings!

im trying to do my first A/B test (http://en.wikipedia.org/wiki/A/
B_testing). so far ive only found
http://visualwebsiteoptimizer.com/sp...heet-in-excel/

My question is this though - how do i transform that one so it
calculates the various ROIs of multiple ad networks, through multiple
ad campaigns, through multiple market segments (oversized women in new
york, chicago and los angeles), through various times of the day,
through various times of the year?

Is such a thing even possible?

Many thanks!

Tony
