Loyalty is an additional feature available in Google Merchant Center for sellers who already have a loyalty program and want to display its benefits on Google.
Activating Member Pricing involves two main steps:
- adding your loyalty details to your Google Merchant Center (GMC)
- updating your product feed with the associated member information.
This allows you to reach your loyalty members with personalized ads and free listings experiences.
