What's one way that an e-commerce client can use Smart Bidding?

The correct answer is that the client should use business data such as profit margin to optimize profit vs revenue. Smart Bidding leverages machine learning to optimize bids for conversions or conversion value. By incorporating business data like profit margins, an e-commerce client can guide Smart Bidding to prioritize conversions that generate higher profit, rather than just maximizing revenue or the number of conversions. This allows for more strategic optimization aligned with business goals. Focusing on lead-generating strategies is incorrect because e-commerce clients typically focus on sales, not leads. Disregarding first-person data is incorrect because combining first-party data with Smart Bidding can significantly improve performance and targeting. Starting with manual bidding first is incorrect; Smart Bidding can learn and perform effectively without a prior manual bidding history, and its algorithms are designed to handle initial data collection and optimization.
