Yo,

Currently I have some sites and we probably do about a million impressions every month. I am looking to monetize all of that traffic through ads. Now can any of you tell me which genre of product from which advertiser would bring the highest CPC based upon your experience. I am familiar with the fact that it depends on the category of product/service being advertised as well as the network (google, adbrite, etc) but, based upon experience, who has been the most profitable for you?

it depends on your niche and your traffic originator countries. Revel more about your niche and here you can get plenty of good suggestions.

I think it really has to be relevant to your traffic to make any sense at all. For instance...if your traffic is generated from adult content...some keywords would do better than others. I think in order to answer this question...it would be best to know the overall genre of your traffic. Don't give away keywords, but telling us your general target audience would make the suggestions easier.

use cpa, ppc is not that good for menetization

i had 9$ once, that was max
