For an Auction campaign, you can set a CPM bid for each selected page type, provided a compatible creative has been added.You will also see a suggested CPM bid range below each input field.
This range is calculated based on the page type by identifying all compatible ad formats.
The minimum value of the range reflects the lowest CPM among these formats, while the maximum represents the highest.
This approach provides a more informed bidding framework, enabling bids to be made more efficiently and competitively based on the available inventory.
