由系统管理的实验

系统管理的实验用于通过创建与原始对照组广告系列一起投放的一个或多个可修改的实验组广告系列来对更改进行 A/B 测试。此工作流程支持以下 ExperimentType 值：

• SEARCH_CUSTOM：包含搜索广告系列的自定义实验。
• DISPLAY_CUSTOM：包含展示广告系列的自定义实验。
• HOTEL_CUSTOM：包含酒店广告系列的自定义实验。
• YOUTUBE_CUSTOM：包含视频广告系列的自定义实验。
• PMAX_REPLACEMENT_SHOPPING：用于测试购物广告系列与效果最大化广告系列相比效果如何的实验。

设置

系统管理的实验的设置遵循以下步骤：

1. 创建 Experiment。
2. 为对照组和实验组创建 ExperimentArm 资源。
3. 修改实验组中的 in_design_campaigns。

1. 创建实验

使用 Google Ads API 运行实验的第一步是创建 Experiment。此资源定义了您要运行的实验的一些关键信息。在此步骤中，您无需指定实验中涉及的任何广告系列。

以下是 Experiment 的一些关键字段的概览：

• name：每个实验都必须具有唯一的名称。
• description：一个可选字段，可供您日后引用。不会影响实验的运行方式。
• suffix：此后缀将附加到实验组广告系列名称的末尾，以便您将它们与对照组广告系列区分开来。我们将在第 2 步中进一步说明这些概念。
• type：要运行的实验类型。对于系统管理的实验，请使用 SEARCH_CUSTOM、DISPLAY_CUSTOM、HOTEL_CUSTOM、YOUTUBE_CUSTOM 或 PMAX_REPLACEMENT_SHOPPING。
• status：创建实验时，请将此字段设置为 SETUP。稍后，当您开始实验后，此字段将用于检查当前状态。
• start_date 和 end_date：指定实验的开始时间和结束时间。
• sync_enabled：默认处于停用状态。如果设置为 true，则在实验运行期间对原始广告系列所做的更改会自动复制到实验广告系列。了解详情。

注意：虽然此处未提供此步骤的直接 REST 代码示例，但您可以使用手动 REST 请求来实现此目的。

请参阅 Google Ads API REST 接口文档和特定于方法的参考页面。您需要根据 proto 定义构建 JSON 载荷。

重要资源：

• 使用 REST
• REST 接口结构
• JSON 字段映射
• 请参阅特定服务和方法的 REST API 参考文档。

2. 创建实验组

接下来，创建 ExperimentArm 资源，以定义实验的对照组和实验组。所有实验组都必须在单个请求中创建。

每项实验都必须有且仅有一个对照组和一个或多个处理组。对照组用于标识要进行比较的基准广告系列，而每个实验组都会生成一个新广告系列，您可以在其中进行更改以进行测试。

您还必须指定 traffic_split，即导向每个组的流量百分比。所有实验组的流量拆分值之和必须为 100。

注意：虽然此处未提供此步骤的直接 REST 代码示例，但您可以使用手动 REST 请求来实现此目的。

重要资源：

• 使用 REST
• REST 接口结构
• JSON 字段映射
• 请参阅特定服务和方法的 REST API 参考文档。

几个要点：

• 必须将一个实验组的 control 设置为 true。
• 所有实验组的 traffic_split 总和必须为 100。
• 对照组必须在其 campaigns 字段中指定一个广告系列。

注意： 创建实验组时，您无法使用部分失败。

3. 修改实验组广告系列

创建实验组（其中 control 为 false）时，API 会自动根据对照组广告系列创建广告系列草稿，并在实验组的 in_design_campaigns 字段中填充其资源名称。您可以将这些设计中的广告系列视为常规广告系列，并根据要测试的更改对其进行修改。对照组广告系列不会受到影响。当您安排实验时，这些更改会具体化为可投放的实际广告系列。

您必须先对处于设计阶段的广告系列做出至少一项更改，然后才能安排实验。

如需检索实验组的 in_design_campaigns，您可以查询 GoogleAdsService：

SELECT experiment_arm.in_design_campaigns
FROM experiment_arm
WHERE experiment_arm.resource_name = "TREATMENT_ARM_RESOURCE_NAME"

提示： 只有在查询中添加 include_drafts=true 参数后，系统才会返回草稿广告系列。

安排实验

创建实验和实验组并修改实验组草稿广告系列后，您可以使用 ExperimentService.ScheduleExperiment 安排实验。这是一项异步操作，可将设计中的广告系列具体化为实际的广告系列，并在实验的 start_date 到达后随时投放。如需详细了解如何处理长时间运行的操作，请参阅异步错误。

报告实验结果

实验运行后，您可以查询指标来比较效果。如需了解详情，请参阅报告指南。

结束实验、将实验升级为正式广告系列或将实验升级为正式广告系列

在实验运行足够长的时间后，您可以使用 ExperimentService 选择结束、推广或升级实验。

• 结束：如果您想停止实验而不应用更改，请使用 EndExperiment。实验组广告系列会停止投放，但不会被移除。这是一项同步操作。
• 推广：如果您对实验组的效果感到满意，并希望将更改纳入原始广告系列，请使用 PromoteExperiment。此操作会将实验组中的更改复制到对照组广告系列，并停止实验组的投放。这是一项异步操作；如需了解详情，请参阅异步错误。注意：无法推广类型为 PMAX_REPLACEMENT_SHOPPING 的实验。
• 完成：如果您喜欢这些更改，但希望它们与原始广告系列分开存在，请使用 GraduateExperiment。这会将实验组广告系列转换为标准的独立广告系列，该广告系列将在实验之外继续投放。对照组广告系列不会被修改。这是一项同步操作。

特定类型的要求

PMAX_REPLACEMENT_SHOPPING：

• 需要正好两个组（一个对照组，一个实验组）。
• 对照组必须在其 campaigns 字段中指定一个购物广告系列。
• 对于实验组，您可以通过以下两种方式设置效果最大化广告系列：
  • 如需制作新的效果最大化广告系列，请将实验组的 campaigns 字段留空。如第 3 步中所述，该 API 会根据对照组购物广告系列自动创建设计中的广告系列。
  • 如需使用现有效果最大化广告系列，请在实验组的 campaigns 字段中指定相应效果最大化广告系列的资源名称。如果您选择此选项，系统不会创建设计中的广告系列，您可以跳过第 3 步。
• 建议您在评估时舍弃前 7 天的统计数据，以便让广告系列有时间完成其效果提升和学习阶段。
• 无法升级。

YOUTUBE_CUSTOM：

• 最多支持 10 个组。
• 如需测试素材资源，请在实验组中设置 creative_asset_testing_info。
