Ji-Won 在预测工具中获得的受众规模较小。他可以使用哪些领英定向功能来扩大受众规模？请选择所有适用选项。

To expand a small audience size in LinkedIn's forecasting tool, Ji-Won can utilize the LinkedIn Audience Network and the Audience Expansion feature. The LinkedIn Audience Network extends campaign reach beyond LinkedIn to third-party apps and websites, increasing the potential audience. Audience Expansion (often referred to as a "broadening tool" or "broad match" for audiences) automatically finds similar audiences to the one Ji-Won initially targeted, based on shared characteristics and behaviors, thereby growing the overall reach. "Saved audiences" are pre-defined groups and don't inherently expand reach; they simply allow for reuse of specific targeting criteria.
