Amazon DSP Inventory Report Placement Sizes 24 September 2025

For personalized assistance with your Amazon Advertising strategy, visit https://amazoniappc.com

In this video, we explore a practical way to optimize your Amazon DSP campaigns using the placement-level data available in the Amazon DSP Inventory Report. If you've already started using supply source reports to optimize your spend, this video walks you through the next step—analyzing ad placement performance by size to reduce wasted budget and improve return on ad spend (ROAS).

The video shows a live account walkthrough where we identify a placement with a very low ROAS that is also one of the top spenders. Based on that data, we explain why this is a clear candidate for removal. You’ll also learn how to navigate to the creative section of your campaign and disable underperforming placement sizes to prevent your ads from showing in poor-performing slots.

We also show how this approach applies to multiple orders, and even if the total monthly spend is relatively low, these small optimizations can lead to meaningful long-term savings and better efficiency in your DSP strategy.

Topics covered in this video include:

How to access the Amazon DSP inventory report
Switching report filters to view by placement size
Sorting data by total cost to find top spenders
Identifying placements with low ROAS
Navigating to creatives and disabling specific placements
Saving money by excluding inefficient inventory types

If you're running programmatic ads through Amazon DSP, this technique helps you spend smarter and focus your budget where it actually drives sales. These insights are actionable, quick to implement, and can be repeated across all your campaigns.

This method adds another layer to your Amazon DSP optimization strategy. In previous videos, we covered how to analyze supply sources and domain-level performance. This placement-based approach complements those strategies and gives you even more control over your ad spend.
