制作需求开发广告系列

检查是否满足最低要求：需求开发广告系列的素材资源必须符合很高的质量标准，因为它们会在 Google 探索和 YouTube 等极具视觉吸引力且侧重于娱乐的平台上投放。

如需制作需求开发广告系列，请执行以下操作：

1. 创建预算。
2. 制作采用适当出价策略的需求开发广告系列。
3. 创建不含类型的广告组。
4. 创建受众群体。
5. 制作素材资源和需求开发广告。

建议您使用 GoogleAdsService.Mutate 方法在单个 API 请求中创建所有必需的实体：

创建预算

创建预算。请注意，需求开发广告系列无法使用共享预算。建议您确保每日预算充足，至少是预期目标每次转化费用出价的 15 倍。 了解详情。

创建广告系列和出价策略

创建预算后，您就可以制作广告系列。

需求开发广告系列的AdvertisingChannelType为 DEMAND_GEN。不应设置 AdvertisingChannelSubType。

为广告系列设置转化目标。

支持的出价策略包括“尽可能争取更多点击次数”“目标每次转化费用”“尽可能提高转化次数”和“目标广告支出回报率”。

制作广告组

创建一个不含类型的广告组，并将其附加到需求开发广告系列。

对于需求开发广告系列，您可以选择在广告组级设置地理位置和语言组条件。

创建广告组时，您还可以配置渠道控制设置，以决定广告的展示位置。
