Different placements may have a different value and performance for you. Hence, Sponsored Discovery uses machine learning to adjust bids based on where you promoted products will be shown.
We also offer you flexibility to bid the same amount across all placements that you have selected. You can do this by selecting the checkbox to apply the same max bid across all placements.
You can only apply the same max bid across all placements when you select All Placements and Standard campaign type.
