Targeting

资源定位管理是 Display & Video 360 API 的核心功能。定位可以分配给多种资源类型，并利用许多其他资源和 ID 空间。本页详细介绍了在采用 Display & Video 360 API 分配的定位条件选项服务时需要注意的限制，以及应实施的最佳实践。

利用定位继承

分配给某些资源的定位条件可由其子资源继承。子资源继承的定位选项可在子资源级别检索，但无法在子资源级别修改。这样一来，品牌保障设置和其他定位条件便可在整个合作伙伴或广告客户范围内强制执行。

下图显示了继承路径：

定位继承关系图

如该图所示，某些定位级别仅支持一部分定位类型。这意味着，某些定位选项无法在更高级别设置并继承，而需要在较低级别设置。

YouTube 及合作伙伴资源中的继承

在 Display & Video 360 API 中，YouTube 及合作伙伴资源的定位继承未得到反映。广告组继承的定位条件无法在 AdGroup 级检索，分配给父资源的 YouTube 定位条件不会由子资源继承。

如需检索广告组的所有功能性定位设置，您应检索广告组、父级订单项和父级广告客户的已分配定位选项。

注意在创建订单项时指定的定位条件

除了继承的定位选项之外，大多数定位选项只能在创建订单项后分配。不过，有几种定位类型在创建订单项时会为订单项分配一组默认的子集值。这些定位类型包括：

尝试创建现有或删除不存在的已分配定位选项会返回错误，因此我们建议您在创建订单项时，了解分配给订单项的完整定位套件。如果您需要检索分配给订单项的各种定位类型的定位条件，请使用 advertisers.lineItems.bulkListAssignedTargetingOptions。

此外，如果未向资源分配相应类型的任何定位选项，系统会默认设置某些设置。例如，如果资源未定义 TARGETING_TYPE_AUTHORIZED_SELLER_STATUS 定位选项，则表示该资源使用的是“授权的直接卖方和转销商”状态。

无法修改 YouTube 及合作伙伴定位

无法使用 Display & Video 360 API 更新专门针对 YouTube 和合作伙伴广告系列的定位。

YouTube 及合作伙伴定位条件包括直接分配给 YouTube 及合作伙伴订单项和广告组的所有定位条件，以及以下任何类型的定位条件：

TARGETING_TYPE_SESSION_POSITION
TARGETING_TYPE_YOUTUBE_CHANNEL
TARGETING_TYPE_YOUTUBE_VIDEO

您可以使用 Display & Video 360 界面直接更新此定位条件，也可以通过上传结构化数据文件来更新。

使用单个选项分配受众群体定位

大多数定位类型的定位选项都是单独分配的。受众群体组定位不遵循此模块化惯例，而是分配在一个可配置的受众群体组定位详情对象中，该对象列出了投放广告时要包含和排除的受众群体的 ID。此受众群体组选项的 assignedTargetingOptionId 一经分配，始终为“audienceGroup”。

这种设计意味着，若要更改受众群体组定位，您必须先删除现有的受众群体组定位选项，然后创建新的受众群体组定位选项并进行所需的更改。您可以使用 advertisers.lineItems.bulkEditAssignedTargetingOptions 通过单个请求完成此操作。

以下示例展示了如何更新受众群体定位，以便积极定位其他 Google 受众群体：

请做好准备，部分定位选项可能会被弃用

定位选项并非一成不变，有时可能会弃用少量选项。定位选项一旦被弃用，就不会影响订单项的广告投放。弃用后，这些选项将从现有订单项中取消分配，尝试检索或分配这些选项的请求将导致错误。

为避免这些错误，我们建议您定期检查存储的定位选项 ID。为了节省配额，我们建议您缓存常用 ID。不过，存储 ID 意味着您可能无法及时发现某个定位选项已被弃用。因此，您应定期使用 targetingOptions.targetingTypes.get 检索所有已存储的定位选项 ID，以确认这些 ID 仍受 Display & Video 360 支持。

如需详细了解之前和即将弃用的重要功能，请参阅我们的已公布的弃用页面。

不要同时发出更新同一订单项的请求

尝试使用多个并发请求更新单个订单项的设置或分配的定位条件时，系统会返回错误。适用的请求包括：

如果您需要同时为单个订单项添加或移除多个已分配的定位选项，则应使用单个 advertisers.lineItems.bulkEditAssignedTargetingOptions 请求。如果您想更新订单项的设置和定位，请将 patch 或 bulkUpdate 请求和相关定位请求排入队列，以确保在第一个请求返回响应之前不会发送第二个请求。

Targeting 使用集合让一切井井有条 根据您的偏好保存内容并对其进行分类。
