Google mentioned in the Google AdWords Help forums and on Google+ that starting on June 26, 2017 Google will be enforcing new Google Shopping feed specification requirements.
The new requirements touch on Minimum Order Value, Shipping-related attributes, and Handling time. Here are the specifics:
Minimum Order Value: Until now minimum order value was only accepted for articles in the food and beverage categories. We are now accepting products priced below your minimum order value in all categories and countries. Set the minimum order value in shipping settings before you upload products with prices below this threshold. If you’re already advertising products with prices below minimum order value in the food and beverage categories, be sure to update your shipping settings and provide the minimum order value by June 26th, 2017. Learn more about adding a minimum order valueShipping-related attributes: To improve the quality of shipping information shown to users, we’re introducing upper bound price and weight value limits for the
shipping
andshipping_weight
attributes to catch outliers we believe to be input errors. Starting June 26th, all items that have a shipping cost or weight above the new limits will be disapproved. Learn more about the updatedshipping
andshipping_weight
attributesHandling time: If you’re targeting the United States, you can now display the estimated delivery date of your product in your Shopping ad. To enable this optional feature, we’re introducing two product data attributes called
min_handling_time
andmax_handling_time
. Use these attributes to indicate the amount of time it normally takes to process an order. Google will compute an estimated delivery date from these attributes and the transit time in your shipping settings in Merchant Center. Learn more about handling timeEnforcement begins June 26th, 2017
Beginning June 26th, 2017, all of the updates will go into full effect and any product data that doesn't meet the requirements in the Products Feed Specification will be disapproved.
