Facebook users don't have ad blindness.

of course they have. people there aren't in buying mood, they are naturally occupied with social networking. that's why they are there, that's the purpose of the platform. it's pointless holding billboards between conversations. consequently, facebook ad performance is abysmal.

otoh, users signalizing purchase intention through a search, that's what google is for. that's where the ad revenue is. basic marketing theory really.
