零售产品信息组

产品信息组用于效果最大化广告系列，可指定要在每个素材资源组中包含或排除哪些产品。因此，商品详情组是在 AssetGroup 级别使用 AssetGroupListingGroupFilter 对象应用的。这与其他类型的零售广告系列类似，在这些广告系列中，商品组是在 AdGroup 级应用的。

效果最大化广告系列中的所有素材资源组都需要包含由 AssetGroupListingGroupFilter 对象组成的有效商品分区树。您可以使用包含 Merchant Center 账号中所有商品的单个节点树来满足此要求。

在界面中，这称为产品组。您可以使用多个维度进行分组，以便包含或排除产品。

分组时，请考虑使用这样的树状结构：在第一级，将产品按条件划分为全新、二手和其他产品条件；然后在第二级，将其他产品条件中的产品按品牌划分为“CoolBrand”产品、“CheapBrand”和其他品牌。

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 Product Condition: (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，并确保每个产品属于且只属于树状结构中的一个单元节点。

您只能针对关联的 ListingGroupInfo.type 为 UNIT 的 AdGroupCriterion 设置出价。

当 AdGroupCriterion 的 negative 设置为默认值 false，且 ListingGroupInfo.type 设置为 UNIT 时，如果广告组的出价策略要求在条件一级设置出价（例如“每次点击费用人工出价”），您必须提供出价值。例如，您需要在 AdGroupCriterion 上设置 cpc_bid_micros 字段。如果您未能为正 UNIT 节点提供必需的出价，则会收到错误消息。

如果 ListingGroupInfo.type 为 SUBDIVISION，则无法为 AdGroupCriterion 设置出价。如果 AdGroupCriterion 的 negative 设置为 true，则出价不适用，因为这是排除对象。

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 会将其与 AdGroup 相关联。

您需要提供至少一个单元节点才能使树状结构生效。该单位可以是根节点，然后成为“所有产品”部门。只有在创建了有效的产品信息组树状结构后，广告才会投放。

效果最大化广告系列产品信息组

效果最大化广告系列中的产品信息组在定位一组产品时效果最佳，因此应优先考虑这种方式，而不是按商品 ID 定位单个产品。您可以使用商品 Feed 中的不同维度（例如自定义标签或品牌）来对商品进行分组。
