I'm running similar sets of keywords on the three large ppcs. if i'm spending x msn, i'm spending about 10x on yahoo, and 80x on adwords. all using basically similar keywords and bids. does adwords really serve that much more traffic? or am i missing something with yahoo and msn? or put another way, adwords gets me 80x more conversions than msn and 10x more than yahoo. what's your experience?
