When running ads on Amazon, implementing the right bidding strategy can make all the difference between a highly profitable campaign and one that drains your ad budget. Amazon provides sellers with several flexible bidding options that enhance control over advertising costs and performance. Two of the most powerful strategies available are Dynamic Bids and Fixed Bids, along with advanced controls such as Placement bidding (Bid+). Understanding how to utilize these tools can help you optimize your campaigns and achieve better ROI.
Understanding Amazon’s Bidding Options
Amazon offers advertisers three main bidding strategies within Sponsored Products campaigns:
- Dynamic Bids – Down Only
- Dynamic Bids – Up and Down
- Fixed Bids
Each bidding method affects how Amazon adjusts your bid based on the likelihood of a conversion.
1. Dynamic Bids – Down Only
With this strategy, Amazon will lower your bid in real-time if it’s less likely to convert. For example, if your initial bid is $1.00 and Amazon determines the ad is unlikely to lead to a sale, it may reduce the bid to $0.75 or lower, ensuring that you’re not overpaying for low-converting impressions.
2. Dynamic Bids – Up and Down
This option is more aggressive. Amazon will increase your bid by up to 100% if a conversion is likely (especially for Top of Search placements) and will lower it when the likelihood is low. This can lead to higher ad spend but also greater exposure and more conversions when used effectively.
Use case: Sellers with well-optimized listings and high-converting keywords often favor this strategy.
3. Fixed Bids
With fixed bids, Amazon will not adjust your bids automatically. What you set is what you pay. While this offers greater predictability in ad spend, it removes Amazon’s smart bidding adjustments that could help capture more high-quality clicks.
Placement Modifiers (Bid+): Maximizing Visibility
Amazon lets you adjust your bid based on ad placement. This strategy, known as Placement Bidding or Bid+, allows you to increase bids by up to 900% for top-performing placements:
- Top of Search (First Page)
- Product Pages
- Rest of Search
Top of Search placements tend to perform exceptionally well due to higher visibility and buyer intent. By increasing bids for this placement, you boost your chances of appearing in those premium spots.
Using Bid+ is a strategic way to balance aggressive bidding only where it counts. Adjusting placement multipliers based on performance data allows sellers to scale campaigns intelligently.
Creating a Winning Bidding Strategy
An effective approach requires more than choosing a single bid type. Here’s how experienced sellers optimize their performance:
- Start with automatic campaigns to gather keyword and performance data.
- Use manual campaigns with Dynamic Bids – Down Only to test new keywords cautiously.
- Implement Up and Down Bids for high-converting keywords with proven performance.
- Monitor placement performance and raise bid modifiers for top placements as needed.
Final Thoughts
Amazon bidding strategies offer advertisers the flexibility to tailor spending based on goals and performance. Whether you’re looking for consistency with Fixed Bids or aiming for higher conversions using Dynamic Bids and placement adjustments, the key lies in constant monitoring, A/B testing, and adjustments based on real data. Mastering these strategies will not only stretch your ad dollars further but also improve your visibility and sales velocity on Amazon’s competitive marketplace.
