Wired is reporting on the recent AdWords CPC increases that have taken a toll on arbitragers and others. The argument in favor of these increases is that it allows Google to display fewer (but more relevant) ads, thus increasing the CTR. On the flip side, some ad buyers are saying that it simply costs more now and the traffic isn’t converting to compensate for the difference.
I am curious if this increase also took effect across Google’s AdSense network?
