A campaign sees weakened delivery and too few impressions to meet set targets
- Has there been a change in targeting or creatives to the campaign?
- Verifying if the decrease is limited to certain sites or across all targeted inventory
- Has any other other campaign(s) started that targets the same inventory, but bids a higher CPM?
- Has there been a decrease in number of bids, or a decrease in win rate?
In version 2 of the UI available in Q4 2017, the Bid Metrics tool will help investigate reasons for decreases in bidding.
