Our Philosophy & Methodology for Placements:
The Purpose of Placement Adjustments:
Placement adjustments are critical for optimizing ad spend and maximizing total sales volume within your target ACOS
Whether with Sponsored Products or Sponsored Brands, the goal is to align your Cost Per Click (CPC) with your Revenue Per Click (RPC) at both the keyword and campaign placement level
Your keyword bids and campaign placement settings together create one CPC. It's therefore crucial to ensure that campaign placement settings and individual keyword bids are working together to hit your sales and ACOS goals
Sponsored Product Placement Calculations:
First, we calculate the RPC for each individual placement
Then we identify the worst performing placement (that is, the placement with the lowest RPC). We set the bid adjustment for this placement to 0%.
Note: Since Amazon doesn't allow us to apply negative adjustments to placements, AdLabs creates a workaround by decreasing all the keyword bids in a campaign to account for the under-performance of the lowest performing placement.The other two placements with stronger performance receive an increase based on their RPC relative to the worst performing placement's RPC.
This strategy allows us to hit the right CPC for each placement
Example:
Top of Search RPC: $2.00
Rest of Search RPC: $1.50
Product Pages RPC: $1.00
In this scenario, since Product Pages has the lowest RPC, we set this placement to 0%.
We then calculate the Rest of Search and Top of Search increases proportionally based on how much higher the RPC is compared to the lowest RPC.
Here is the formula:
Here’s how those calculations would follow for this example:
Rest of Search Adjustment = (RoS RPC / PP RPC) - 1
Rest of Search Adjustment = ($1.50 / $1.00) - 1
Top of Search Adjustment = (RoS RPC / PP RPC) - 1
Top of Search Adjustment = ($2.00 / $1.00) - 1
This would result in a +50% bid adjustment for Rest of Search and +100% for Top of Search.
Sponsored Brand Placement Calculations:
Things are a little different with Sponsored Brands.
In the Amazon Ad Console, they don’t allow us to adjust bids for Top of Search. We can only to increase or decrease for placements non-Top of Search.
However, through the API, we can either increase OR decrease for any of the 3 core placements (Top of Search, Rest of Search, and Product Pages).
For this reason, the SB Placement calculations are much simpler:
With this logic, each placement is either increased or decreased based on how much better it is performing to the “total.”
Because we can both increase & decrease for placements, there is no need to reduce the “base bid” like in Sponsored Products.
A Solution for Low-Data Campaign Scenarios
If a specific campaign placement has low data (e.g., 1 click and 1 order), we will then reference the placement performance for that campaign's Optimization Group in order to get more reliable data.
If the Optimization Group itself doesn't have enough data, we will reference the overall placement performance for the entire advertising profile.

Our Solution to the "Low Data" Problem
For each campaign placement adjustment on the Preview Optimizations screen, you will see a badge in the "Reason" column for whether that placement calculation came from the campaign itself, it's group, or the profile:
