Is there anyway to distinguish traffic coming yahoo search marketing (cpc) and from yahoo organic search results? They seems to be all lumped into "yahoo/organic". With google I get "google/cpc" and "google/organic" categories which is very helpful. I know isa a google product but I would think there was a way for it to differentate yahoos traffic.
Yep, this is pretty straight forward. You need to tag the links in Yahoo to include information to tell Google Analytics that it came from a cpc campaign. For example, a link to http://www.example.com/ would be: http://www.example.com/?utm_source=Yahoo&utm_medium=cpc&utm_campaign=SampleCampaign . You can include utm_term as well if you want the keyword that shows in reports to be the one you bid on, or you can leave off that parameter and it'll pick up whatever the user typed into the search box.
