When setting up a product feed in the Google Merchant Center, which of the following attributes is optional?
- image_link
- availability
- product_type
- price
Explanation:
The correct answer is **product_type**. When setting up a product feed in the Google Merchant Center, the attribute **product_type** is optional. While attributes like image_link, price, and availability are essential for ensuring that product listings are accurate and informative, the product_type attribute is not mandatory for creating a functional product feed. Product_type is typically used to categorize products within the feed, providing additional organizational structure for product groups or for more specific ad targeting. However, its absence doesn’t hinder the functionality of the feed or the performance of Shopping campaigns. Therefore, if a business is unsure about how to categorize its products or simply doesn’t need this level of granularity in its feed structure, it can opt not to include the product_type attribute without affecting the overall functionality or performance of the feed in the Google Merchant Center.
