Match the bidding strategy to the definition. Amazon will use your exact bid for all opportunities and won’t adjust your bids based on likelihood of a conversion.

The correct answer is "Fixed bids" because this bidding strategy uses the exact bid amount set by the advertiser for all opportunities without any real-time adjustments. With fixed bids, Amazon does not alter the bid based on the likelihood of conversion, meaning that the bid remains constant regardless of how likely a click is to result in a sale. This approach provides advertisers with full control over the amount they are willing to pay for each click, but it may not optimize the bid in response to factors like conversion probability. In contrast, "Dynamic bids - down only" reduces bids for clicks less likely to convert, and "Dynamic bids - up and down" adjusts bids both up and down depending on the conversion likelihood.
