How can I run bid experiments at the Ad Group level
I want to run a bid experiment at the ad group level, I watched the following tutorial: https://www.youtube.com/watch?v=naEcMRml330&index=3&list=PLCF19FEA9FD29F866
however, when I segment ad groups into control and experiment, Adwords does not present the option for me to change the bid of the experimental or control ad groups, why is that? Am I doing anything wrong?
