Why are several of my TrueView Targeting groups getting ZERO impressions?
I am currently running a couple of TrueView In Stream campaigns. Within each IS campaign each targeting method gets its own ad group. The targeting groups that are getting 0 impressions target remarketing lists and topics. I thought raising the bid to $9 would get more impressions but so far no luck.
The bids for the remarketing list are high and the lists have well over 200,000 people in them.
In the Topics targeting groups the bids are high and a I've selected a range of topics relevant to our ads to find out which topics perform best. Still no impressions.
Any insights as to what is happening and why it's happening would be greatly appreciated.
