One of my client's sites is #1 in Google and Overture via PPC also #4 in Google organic SERPs, #1 in Yahoo organic SERPS. The natural Yahoo listing only gets about 10% to 15% more clicks then the Overture listing whereas in Google the #4 organic Google listing is getting about 600% to 650% more traffic then the #1 Google PPC result. I cannot guarantee our Google PPC listing is always #1, but it is every time I or my client has ever checked it. Bottom Line: organic listings are MUCH more valuable.
