AdWords will always use your Content Network placement bid.
AdWords always uses the most specific bid available. If you have not made a specific bid for an individual placement, then your overall automatic placements default bid or managed placements default bid will be used.
Here's the general order of bids, from most specific (and highest priority) to lowest:
- Individual placement bids
- Managed placements bid
- Automatic placements bid
Bid modifiers, such as changes for ad scheduling or demographic bids, are applied after your primary bid is chosen.
