The updated documentation clarifies merchant return policies and loyalty programs by specifying how and where these should be defined. It states that offer-level return policies support only a limited subset of organization-level return policies, and that merchant-level return policies must be defined under Organization markup using the MerchantReturnPolicy type. This approach ensures a consistent return policy across the entire catalog, while product-level return policies under Offer are meant only for exceptions and support fewer properties.
Regarding loyalty programs, the documentation now clarifies that loyalty program information must be defined separately from offer-level loyalty benefits (such as price and points) under Organization markup, either on a separate page or within Merchant Center. Additionally, Google currently does not support loyalty benefits related to shipping and returns.
These updates aim to remove ambiguities and provide clearer guidance on structuring return policies and loyalty programs within merchant listings.
