A startup wants to test a new product to determine their initial cost per acquisition. Which bidding strategy can help them acheive this objective?

Maximize Conversions is the best strategy for determining initial cost per acquisition (CPA) because its primary goal is to get as many conversions as possible within your budget. This directly helps you understand the cost associated with each conversion. Maximize Conversion Value focuses on the monetary value of conversions, which isn't the primary goal when first determining CPA. Target Impression Share aims to achieve a certain percentage of impressions, not conversions. Target ROAS (Return On Ad Spend) focuses on revenue relative to ad spend, which is more advanced and requires historical conversion value data, making it unsuitable for an initial CPA test.
