Ad Split Testing

[WayneSh21]

How long do you guys wait while split testing ads before coming to a conclusion and making a change based on your results? A few day? A certain amount of clicks? I am wondering what the general consensus is.

Well you need statistically meaningful data... I'd tell you how to calculate that but I was never very good at statistics but google can help

Yeah that's the question. I usually wait about 3 or 4 days (on most campaigns) before I consider my data as "statistically meaningful" but I doubt that is long enough to be accurate, especially when conversions etc such can vary so much just from one day of the week to another... I like to constantly tweak my campaigns but I am starting to wonder if I am making too many changes too often without giving each enough time to become "statistically meaningful"...

go to splittester.com as suggested above. It will tell you which is better and what percentage of accuracy it thinks the choice is.
