What
: Added a new section on "Sale duration" to the
Merchant listing guide
. This explains how to use the
validFrom
,
validThrough
, and
priceValidUntil
schema.org properties to set the effective range for sale prices, including best practices and examples for placement on either
Offer
or
PriceSpecification
nodes.
Why
: This aligns schema.org usage with the Merchant Center feed attribute
sale_price_effective_date
,
providing clear instructions and best practices for merchants using structured data.
