From what I can see, you can't distinguish between the organic referrals and the ppc referrals from Yahoo and MSN. Is it possible to do this? Am I missing something?
Currently its not possible to track ppc referrals from Yahoo and MSN. check here - http://www.google.com/support/analytics/bin/answer.py?answer=27250&query=yahoo&topic=&type=
they'd probably need some sort of special permission from yahoo and msn to do this. or else they're just protecting their territory
it is currently not possible to track ppc referrals from Yahoo and MSN at Google Analytics.. but might be in future such facility will be there....
