firstly, sorry for my bad english. I see that Google try to put their CPA on the way and may be option for publisher who still want to monetize for cpc programs. However, I see many advertiser in here wanted to change from cpc to cpa (or ppa) because of clicks fraud but publisher still wanted to stick with cpc because it's easy for them to get paid. I just curious if adsense wouldn't be last long because of advertiser dislike cpc. In my opinion, ppa not good for publisher also, if user delete their cookies or did not take any action, publisher just send free traffics to advertiser and earn nothing. How long adsense would be alives? 2 years? 5 years? 10 years? or it would be never died.
yeah i agree. its hard to earn from PPA as far as the publishers are concerned especially with low to medium traffic websites.
Ya I've been wondering about this too since Google has their beta CPA thing out. Damn google always looking to make money
