Which do you like CPA, CPC and CPM?
I have several campaigns going and while I like the CPM model the best, my Alexa rating does not cut it.
I know they all have their unique benefits, CPM is great for any type of branding campaign because you are not concerned necessarily with the amount of time the ads are clicked, but rather that the ads are displayed. CPA seems to be the preferred method for new advertisers and CPA does allow one to determine exactly what you are willing to pay for a download or sale working directly off of the numbers.
However, in the end my preference has to be CPC as the most effective CPC advertising campaign costing one less with your target CPA optimization.
