通过酒店广告组，您可以将自己的酒店按照多个维度划分为多个酒店信息组，这样就可以相应地调整每个组的出价。分组时，请考虑使用这样的树状结构：在第一级，将酒店大致划分为五星级酒店、四星级酒店和其他星级酒店；然后在第二级，将其他星级的酒店划分为“美国”酒店、“英国”酒店和其他地区的酒店。
树状结构中的每个节点要么是一个子类，要么是一个单元，具体由 ListingGroupType 指定。子类会在树状结构中延伸出一个新的级别，相当于树枝，而单元则是树状结构上的树叶。每个子类之间必须始终完全分割开来，因此必须包含一个代表其他的节点。在下面的示例中，root 和 Hotel Class: (Other) 节点都是子类。这种包含子类和单元的树状结构允许您在单元级别设置出价，并确保每项酒店信息属于且只属于树状结构中的一个单元节点。
节点是 ListingGroupInfo 类的对象，其中包含 ListingGroupType 字段，用于指示节点是单元还是子类。将 AdGroupCriterion 的 ListingGroupInfo 设置为 listing_group 会将其关联到 AdGroup。
设置百分比形式的每次点击费用出价
您只能在单位节点上设置 AdGroupCriterion 的 percent_cpc_bid_micros。在子类节点上尝试执行此项设置操作，将会失败并显示错误。
信息维度
ListingGroupInfo 还有一个 case_value，它是一个 ListingDimensionInfo，包含几种维度类型中的一种。ListingGroupInfo 表示与您的酒店相关联的值，例如酒店 ID、酒店所在国家/地区或酒店星级。有关可用的 ListingDimensionInfo 类型的完整说明，请参阅参考文档。
子类的每个直属子级都必须具有属于相同 ListingDimensionInfo 子类型的 case_value，但根节点除外，它没有 case_value。
另请注意，每个子类都必须包含一个正确类型的“空”case_value，用于表示“所有其他值”。
如需了解更多详情，请查看下面的代码段，该代码段添加的是酒店信息组树状结构的第一级。

ListingDimensionInfo 的可用维度
以下 ListingDimensionInfo 类型可用于酒店广告：
临时 ID
在服务器处理了创建广告组条件的 mutate 请求后，系统才会向这些条件分配 ID。不过，ListingGroupInfo 在处理完成前都是无效的，因此每当您创建子类时，还必须在相同的操作中至少创建一个子级子类。
ListingGroupInfo 的 parent_ad_group_criterion，您可以使用临时条件 ID。这些临时 ID 只是具有本地唯一性的标识符，不是具有全局唯一性的标识符，仅可在单个 mutate 请求的上下文中应用。任何负整数（例如 -1）都可以用作临时 ID。
处理请求时，每个 AdGroupCriterion 都会照常分配一个正整数的全局 ID。
