But then I realized that I can't just setup a new campaign and advertise ONLY on the Search network, the way you can for the content network. Darn.
Are there any creative ways that I could somehow enable Search network traffic and track it separately?
Or do I basically just have to enable the Search network in all of my primary campaigns, let it run for a week, and then compare my stats/conversions for the week vs. the week prior when Search network wasn't enabled? I'm scared that this has the potential to ruin my CTRs, etc.
