Campaigns reactivated... CPCs doubled
We are using target cpa and the campaigns were paused for 2 days. After reactivation the CPCs have doubled. Has anyone had the same experience? Has the bid strategy tool started to learn anew?
Re: Campaigns reactivated... CPCs doubled
It's more likely the problem is that something happened during those two days that the strategy couldn't learn about, because you weren't running ads. For example, if the competition raised their bids during those two days, your strategy is going to be two days "behind" in adjusting to that.
