I have a campaign with four ad groups running in the search networks and content networks. All ad groups are performing well since they get many conversions. A week ago we pause our campaign and then resume it after 4 days. Then I made this Placement campaign with the same ad group name of the ad group that is really performing best of my first campaign with same image ads and text ads. What happened is that the best performing ad group of my first campaign got no more conversions and only got few impressions and I also got few conversions on my placement campaign. Did the two ad groups from the two campaigns had a conflict with each other since they have same URL, image ads and text ads? Should I pause my placement campaign?
