실험 부문 만들기

실험을 만든 후에는 실험에 테스트 중인 항목에 관한 자세한 정보를 제공하기 위해 여러 실험 부문을 만들어야 합니다.

실험 부문

ExperimentArm는 실험을 위해 실행하는 비교의 한 부분을 나타냅니다. 모든 실험에는 항상 하나의 대조 부문이 있어야 합니다. 이 부문은 다른 부문을 비교하는 기준을 형성하는 기존 캠페인입니다.

다른 부문을 실험 부문이라고 하며, 이 부문에서는 실험을 시작하기 전에 캠페인을 변경합니다.

ExperimentArm에는 traffic_split 설정도 포함됩니다. 이를 통해 실험의 각 부문으로 전달되는 트래픽의 비율을 지정할 수 있습니다. 각 부문에서 트래픽 분할을 지정해야 하며 모든 부문의 트래픽 분할 값의 합계는 100이 되어야 합니다.

이 트래픽 분할 제한으로 인해 모든 실험 부문은 동일한 요청에서 만들어야 합니다.

위 예시의 몇 가지 핵심 사항은 다음과 같습니다.

  • 각 부문의 nameExperiment 내에서 고유해야 합니다.
  • traffic_split는 모든 실험군에서 합계가 100이 되어야 합니다.
  • 정확히 하나의 부문은 controltrue로 설정해야 합니다. 다른 모든 부문은 controlfalse로 설정해야 합니다.

    컨트롤 암만 캠페인을 하나만 보유하는 campaigns 배열을 지정합니다.

실험 부문

모든 실험 부문을 만들면 실험 부문(controlfalse로 설정된 부문)의 in_design_campaigns 필드가 자동으로 채워집니다. 코드 예와 같이 응답 콘텐츠 유형을 MUTABLE_RESOURCE로 설정하여 API 응답에서 필드를 가져올 수 있습니다. GoogleAdsService 쿼리를 통해 가져올 수도 있습니다.

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

디자인 중인 캠페인

이러한 디자인 중인 캠페인은 일반 캠페인으로 간주할 수 있습니다. 실험에서 테스트하려는 사항을 이러한 캠페인에 적용합니다. 대조군 캠페인은 영향을 받지 않습니다. 실험을 예약하면 이러한 변경사항이 광고를 게재할 수 있는 실제 캠페인으로 구체화됩니다.

이러한 설계 중인 캠페인은 기술적으로는 임시 캠페인입니다. GoogleAdsService에서 이를 찾으려면 쿼리에 include_drafts=true 매개변수를 추가합니다.

실험을 예약하려면 디자인 중인 캠페인을 하나 이상 변경해야 합니다.
