Emily is creating a campaign for a large insurance company's auto insurance and is choosing an automated bid strategy. The aim is to use Microsoft Advertising’s data-driven bidding to get as many online purchases as possible. Which bid strategy should Emily choose?

Maximize Conversions is the best choice because its primary goal is to generate as many conversions as possible within your budget, leveraging Microsoft Advertising's data to optimize bids for this specific outcome. Target Cost Per Action (CPA) is designed to achieve a specific average CPA, not necessarily the highest volume of conversions. Enhanced Cost Per Click (eCPC) adjusts bids to help get more conversions but still focuses on clicks, not directly maximizing conversion volume. Target Impression Share aims to achieve a certain percentage of impressions, which doesn't directly correlate with maximizing online purchases.
