Čo je účelom skupín výrobkov v nákupnej kampani?

Product groups in Shopping campaigns allow you to organize and bid on specific sets of products from your product feed. This enables precise control over which products are advertised within a given campaign or ad group. For example, you can create a product group for "red shoes" and set a specific bid for it, separate from "blue shoes." The other options are incorrect because: Product groups are not keywords; keywords are used in search campaigns, while Shopping campaigns use product data. Product groups are not predefined themes; they are dynamically created based on attributes from your product feed. Product groups are not remarketing lists; remarketing lists are audience segments used for targeting, not for organizing products.
