New Customer RoAS
New Customer RoAS calculates the effectiveness in driving new sales from customers. Choosing to optimize for new customers reduces what qualifies as an attributed sale in your campaign. This therefore reduces the maximum allowable RoAS target for new customers.
New Customer Macro
In order to optimize for new customers, you need to have the new customer macro implemented in your Sales Pixel.
The CUSTOMER_TYPE macro should be populated with “0” if a new customer, or with “1” if an existing customer.
If your store is built using an e-commerce platform that has an integration with SourceKnowledge, you do not need to add this macro, as it is already populating automatically.
If you have a custom integration, you will need to add this macro manually. You can find your Sale Pixel under Tools in your Dashboard.
