“Set Publisher A’s floor to $0.10 CPM”

How Floors Work

The effective floor uses a 4-level hierarchy:

1. Publisher floor — base floor set on the publisher
2. Pool floor — floor from the inventory pool the publisher belongs to
3. Dynamic floor (Guide) — automatically adjusted based on fill rate
4. Bid request floor — bidfloor in the incoming OpenRTB request

The highest of these wins. If fill rate is very low, Guide may lower the dynamic component to attract more bids.
