Seems it is easier said than done. How to measure the baseline result? e.g. If a client also uses PPC before you step in, how do you track the "before" traffic by seperating PPC traffic from natural search traffic?
I think it cannot simply says ask for clients or just trust them to reveal the traffic. First, they may not sure about it. Second, a big company may have more than 1 PPC account controlled by more than 1 person. Third, they may tell lies so as to inflat the "before" traffic.
Any idea?
BTW, any good website traffic tracking service that allows us to distingush PPC traffic and natural search traffic? and also allows tracking non-english keywords?
