How to use Campaign Experiments to split test ad copy?
I am trying to use Campaign Experiments to split test ad copy on search ads - I am fed up with split testing ads the traditional way, since Avg. Pos for each ad is never quite the same and skews the CTRs. I would rather rely on Google's calculations to tell me significance.
I have set up the Experiment as follows (this is the Ad Group > Ads view):
In other words:
I have set my Control ad to "Control Only", and my second ad to "Experiment Only".
The trouble is, and as you can see, Experiments is not comparing the two ads. For example, the top ad is giving me Significance notifications against the zero traffic Experiment segment in its own ad. Not helpful at all.
Am I missing something? How do I setup an ad copy experiment that actually works in Experiments? Or should I revert back to the traditional method?
