Client, customer, and context
Harvest group is a leading commerce agency specializing in retail media strategies across Amazon, Walmart, Kroger, and more. They were looking for a way to use Google Ads to drive incremental traffic to both Amazon and Walmart for their client. The big question - does having multiple ads on Google search results pages increase traffic to retailers, without increasing total ad costs?
Setting the strategy and goals
The central piece of the puzzle for this test was to be able to measure the impact of owning multiple spots on the SERP and its effect on Google CPCs.
Very important to this customer was to monitor the cannibalization of DTC traffic. The goals for this test were:
- Split ads without overlap: Run distinct Google Ads to Amazon and Walmart without bidder conflicts.
- CPC control: Maintain cost efficiency while expanding campaign scope.
- Precise attribution: Track click-to-purchase paths for full retail conversion visibility.
After a simple setup within the Ampd platform, Harvest group was able to implement two dedicated Google Ads Campaigns: One for Brand-X -> Amazon and one for Brand-X -> Walmart, each targeting the same high-intent search terms. Using smart tagging and automated attribution, the platform ensured accurate conversion mapping without elevating CPCs.
