I was wondering how long do you usually let your website marketing/advertising campaigns run for to collect enough data to see if that certain marketing/advertising method is working for your website?
I'm guessing running for only a couple of days or a week; wouldn't give me a good gauge as to whether a marketing/advertising campaign is resulting in a good ROI. Maybe a month? 2 months? 3 months? etc.?
