You’re setting up a product feed in Merchant Center for the first time, and you realize you don’t have availability for each product. What will happen if you try to upload the feed in Google Merchant Center?

Because availability is a required attribute, Google will disapprove your product feed in Merchant Center until all mandatory attributes, including availability, are properly included.

• Availability is an optional attribute, so Google’s system will flag it as a warning for you to resolve in the future.
• Availability is not an attribute in the product feed, so Google’s system will disapprove the feed.
• Availability is a required attribute, so Google’s system will flag it as a warning for you to resolve in the future.

Explanation:
Availability is a required attribute when creating a product feed in Google Merchant Center. If omitted, Google will disapprove the feed, as accurate and consistent product data between your feed and website is essential to avoid item disapprovals. Failure to meet these standards can result in product disapproval, requiring corrective action to restore compliance.
