广告组级目标覆盖
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。
以下替换项可供使用。
替换出价策略
出价策略只能在广告系列一级设置。因此,举例来说,如果某个广告系列已分配 TARGET_ROAS
策略,则在该广告系列的某个广告组中设置 TARGET_CPA
字段将不会产生任何效果。
同样,如果您使用的是不支持手动出价的广告系列级出价策略,手动设置出价将不会产生任何效果。例如,如果您的广告系列使用TARGET_ROAS
作为标准出价策略,并且您为该广告系列中的各个关键字设置了每次点击费用的最高出价值,系统会忽略关键字级出价,但不会显示错误。如果您改用人工出价,系统就会采用关键字级出价。如需了解详情,请访问帮助中心。
在广告组一级替换目标广告支出回报率
TargetRoas
出价方案的 target_roas
字段或设置了 target_roas
字段的 MaximizeConversionValue
可以在广告组一级通过设置广告组的 target_roas
字段进行替换。无法替换出价方案的其他字段。
如需移除替换,请发送一个 mutate 请求,其中包含一个空字段值,但仍需在字段掩码中提供路径,以取消设置广告组的 target_roas
。尝试替换与投资组合策略相关联的 TargetRoas
方案的 target_roas
字段会导致错误。
您可以使用 effective_target_roas
字段检索广告组的有效 target_roas
值,并使用 effective_target_roas_source
字段检索其来源。
在广告组一级替换目标每次转化费用
如果出价方案为 TargetCpa
,则其 target_cpa_micros
字段或 MaximizeConversions
(且其 target_cpa_micros
字段已设置)可以在广告组一级通过设置广告组的 target_cpa_micros
字段进行替换。出价方案的其他字段无法被替换。
如需移除替换,请发送一个 mutate 请求,其中包含一个空字段值,但仍需在字段掩码中提供路径,以取消设置广告组的 target_cpa_micros
。
您可以从 effective_target_cpa_micros
字段检索广告组的 target_cpa_micros
有效值,并从 effective_target_cpa_source
字段检索其来源。
