Campaigns now may be set to various bidding strategies. Each different strategy will dictate to Amazon how your funds may be spent.
- Dynamic Bids – Down Only: The default strategy for older campaigns. Your bid price will not go beyond the maximum dollar amount you set.
- Dynamic Bids – Up and Down: Choosing this will allow Amazon to increase your bids for clicks that may be more expensive but that they deem more likely to convert into a sale, while also reducing in the same manner as “Down Only.”
- Fixed Bids: Choosing this will tell Amazon to use only your exact bid price for any and all click opportunities.
