What is the purpose of having product ratings in a shopping campaign?

The purpose of having product ratings in a shopping campaign is fundamentally to provide potential buyers with quality insights about products. Product ratings serve as a critical piece of information for consumers, helping them make informed purchase decisions by showcasing the experiences of previous customers. This transparency can significantly influence a buyer's trust and interest level in a product. When shoppers see favorable ratings, they are more likely to view the product positively, which can lead to higher conversion rates.

The other options, while they may touch on different aspects of online marketing and advertising, do not directly relate to the role of product ratings in shopping campaigns. Enhancing ad visibility on social media is more about marketing strategies than product evaluation. Managing daily budgets pertains to financial aspects of advertising but does not connect to consumer perception of product quality. Optimizing keyword strategies relates to SEO and ad targeting, which is distinct from the assessment of products based on customer feedback. Thus, the focus of product ratings is squarely on informing and reassuring potential buyers, aligning perfectly with option B.
