某代理机构的一位营销者负责一家外卖公司的应用广告系列。他们投放广告系列的目标是获取新用户。 为了实现客户的目标，最好选择以下哪一种出价策略？

Target Cost Per Install (tCPI) is the most suitable bidding strategy for acquiring new users for an app, as it directly optimizes for app installs. This strategy allows the marketer to set a desired cost for each new install, and Google Ads will automatically adjust bids to achieve that target, maximizing the number of installs within the budget. Cost Per Click (CPC) optimizes for clicks, not necessarily installs. Target Return On Ad Spend (tROAS) is designed for maximizing revenue, which is a later-stage goal than initial user acquisition. Cost Per Mille (CPM) optimizes for impressions and is typically used for brand awareness, not direct user acquisition.
