Over the course of this and last week I have seen my CPM for new campaigns skyrocket for no reason. My ads are all "above average" in all categories according to the ad relevance diagnostics, yet my CPM on new campaigns is terrible
Meanwhile, my old campaign continues getting cheap conversions and a low CPM.
Is anyone else experiencing this?
