Hey guys! I was wondeirng if someone could explain to me in which case each one of these is used. ALso, I am attempting to launch a campaign which aims at branding a product rather than selling it. Should I be using CPC or CPM? Cheers!
CPC is best, since you will be billed only if you get visitor, while as cpm you will get banner impressions, and it depends upon banners you advertise.
