Создать руки для экспериментов

После создания эксперимента вам необходимо создать несколько его групп, чтобы предоставить эксперименту больше информации о том, что именно вы тестируете.

Экспериментальное оружие

ExperimentArm представляет собой одну часть сравнения, которое вы выполняете для эксперимента. Во всех экспериментах всегда должно быть ровно одно управляющее плечо . Это направление представляет собой существующую кампанию, которая формирует основу для сравнения другого направления.

Другие группы называются лечебными, и в них вы вносите изменения в кампанию перед началом эксперимента.

Примечание. В настоящее время существует ограничение на одну группу лечения в эксперименте.

ExperimentArm также содержит параметр traffic_split . Это позволяет указать процент трафика, направляемый на каждую группу эксперимента. Для каждого плеча должно быть указано разделение трафика, а сумма значений разделения трафика во всех плечах должна составлять в сумме 100.

Из-за этого ограничения на разделение трафика все группы эксперимента должны создаваться в одном запросе.

Примечание. При создании групп экспериментов нельзя использовать частичный отказ .

Несколько ключевых моментов в приведенном выше примере:

• name каждой группы должно быть уникальным в рамках Experiment .
• traffic_split должен в сумме составлять до 100 по всем направлениям.

• Ровно для одной руки должно быть установлено значение true для control ; все остальные руки должны иметь значение false .

  Только рычаг управления определяет массив campaigns , который содержит только одну кампанию.

Лечебные рукава

После того как вы создали все группы эксперимента, группы лечения (группы, для которых установлено control false автоматически заполняют свое поле in_design_campaigns . Вы можете получить поле из ответа API, установив для типа содержимого ответа значение MUTABLE_RESOURCE , как в примере кода. Вы также можете получить его с помощью запроса GoogleAdsService :

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

Совет: Возможно, будет полезно выбрать поле experiment_arm.control , чтобы указать, какие ветви являются лечебными. Поскольку это необязательное логическое поле, API не возвращает false значения. Пустой ответ эквивалентен false .

Кампании в дизайне

Вы можете рассматривать эти встроенные кампании как обычные кампании. Вносите в эти кампании любые изменения, которые хотите протестировать в своем эксперименте; кампания по контролю не будет затронута. Как только вы запланируете эксперимент, эти изменения материализуются в настоящую кампанию, в которой можно показывать рекламу.

Эти запланированные кампании технически являются черновыми кампаниями. Если вы хотите найти их в GoogleAdsService , добавьте в запрос параметр include_drafts=true .

Прежде чем можно будет запланировать эксперимент, в встроенную кампанию необходимо внести хотя бы одно изменение.
