A retailer wants to maximize the total value of online sales while staying within a specific daily budget, regardless of the ROI on individual dollars. Which strategy should they use?

Maximize conversion value is the correct strategy because it automatically optimizes bids to get the most conversion value for your budget. Since the retailer wants to maximize the total value of online sales, this bidding strategy directly aligns with that goal, prioritizing higher-value conversions. Target ROAS (Return On Ad Spend) would be suitable if the retailer had a specific ROI target in mind, but the question states they are not concerned with ROI on individual dollars. Target CPA (Cost Per Acquisition) focuses on getting as many conversions as possible within a cost target, not necessarily maximizing their total value. Maximize conversions aims to get the most conversions, regardless of their individual value, which doesn't meet the requirement of maximizing total value.
