您的客户想要在下一季度的特色茶饮广告系列投放中使用优化型定位。 以下哪个选项描述了优化型定位的作用？

Optimized targeting is an audience expansion solution that uses Google AI to go beyond manually selected audiences. It helps find new and relevant audiences that are likely to convert, based on real-time conversion data. This allows advertisers to discover high-performing segments they might not have considered, improving campaign efficiency and reach. The other options are incorrect because: "Optimized targeting uses your own customer lists..." describes Customer Match, not optimized targeting. "Optimized targeting helps marketers reach target audiences across Google's vast ad network..." is a general description of Google's advertising capabilities, not specific to optimized targeting. "Optimized targeting combines different datasets to create refined audiences..." describes audience segmentation or custom segments, not optimized targeting's primary function of expansion.
