For an Auction campaign, you can set a CPM bid for each selected page type, provided a compatible creative has been added.
The minimum bid for each page type is determined by the combination of page type and creative format selected earlier.
If multiple formats are assigned to a page type, the highest minimum bid among them will be used as the required minimum for that page.
This allows for flexible, value-based bidding across placements, ensuring you’re bidding appropriately based on where your ads will appear and the formats used.
