In which of the following situations should an advertiser consider using automated bidding?

Automated bidding is most effective when optimizing for a specific performance goal, such as sales efficiency. For Sponsored Brand campaigns, which often aim to drive consideration and sales for a brand's entire product portfolio, automated bidding can efficiently adjust bids to maximize sales within a given budget. While automated bidding can be used for both Sponsored Product and Sponsored Brand campaigns, the question specifically asks for a situation where an advertiser should consider using it. Optimizing Sponsored Brand campaigns for sales efficiency is a strong use case because these campaigns can have a broader impact on overall brand sales. Optimizing for brand awareness (an upper-funnel metric) is less directly tied to the immediate sales efficiency that automated bidding excels at.
