Split Testing Ads on Facebook...
Could anyone tell me the best way to split test ads on Facebook?
I'd be interested in experinces running more than one ad at the same time for the same demograhics i.e. likes and interests, or whether its best to run one ad at a time for exact same demographics??
Cheers
PS I understand about just changing one variable at a time, its more how to split test using multiple ads at the same time like in Adwords...
