您正在规划将在未来投放的广告系列，该广告系列用于宣传一个主要面向 18-34 岁成人的全新电视节目。您想了解您的广告系列在该人群中的曝光率。 您可以使用哪种 Display & Video 360 功能来了解这些指标？

The Reach Planner tool in Display & Video 360 is specifically designed to estimate the potential reach and frequency of campaigns among target audiences before launch. It allows you to input demographic information (like age 18-34) and campaign parameters to predict impressions and unique reach. The "规划" (Planning) workspace is a broader area that includes various planning functionalities, but the Reach Planner is the specific tool for this task. Data analysis tools are used for post-campaign analysis, not pre-campaign forecasting of reach. The forecasting tool might offer some predictions, but the Reach Planner is tailored for audience reach and frequency metrics.
