生成覆盖面曲线

收集媒体方案的定位设置和产品组合后，您可以使用 ReachPlanService 中的 GenerateReachForecast 方法生成预算与潜在覆盖面之间的曲线。如需详细了解请求字段，请参阅术语表和媒体资源投放计划指南。

保存曲线

您只能保存单个曲线，以便为用户提供便利。严禁批量缓存曲线。如果您确实需要批量生成曲线，请先与您的 Google 代表联系。

YouTube 优选的变化

覆盖面规划服务中的 YouTube 优选频道组 (YTS) 现在支持频道组级定位（与之前的“全网播出”相比），适用于采用即时预订价格的所有符合条件的 YTS 位置。使用即时预订功能时，请求 YTS 预测时也可能会出现以下错误：

  1. 可用的广告资源不足
  2. 停用非支出账号

代码示例

该曲线包含绝对值的展示次数和用户覆盖面，以及与所请求受众特征和国家/地区的普查人口和 YouTube 受众群体规模相对应的总体规模。
