Los experimentos administrados por el sistema se utilizan para realizar pruebas A/B de los cambios creando una o más campañas de tratamiento modificables que se ejecutan junto con una campaña de control original.
Este flujo de trabajo se admite para los siguientes valores de ExperimentType:
SEARCH_CUSTOM: Es un experimento personalizado que consta de campañas de Búsqueda.DISPLAY_CUSTOM: Es un experimento personalizado que consta de campañas de Display.HOTEL_CUSTOM: Es un experimento personalizado que consta de campañas de hotel.YOUTUBE_CUSTOM: Es un experimento personalizado que consta de campañas de video.PMAX_REPLACEMENT_SHOPPING: Es un experimento para probar el rendimiento de tus campañas de Shopping en comparación con las campañas de máximo rendimiento.
Configuración
La configuración de los experimentos administrados por el sistema sigue estos pasos:
- Crea un
Experiment. - Crea recursos
ExperimentArmpara el control y el tratamiento. - Modifica el
in_design_campaignsen los grupos de tratamiento.
1. Crea un experimento
El primer paso para ejecutar un experimento con la API de Google Ads es crear un objeto Experiment. Este recurso define información clave sobre el experimento que deseas ejecutar. En este paso, no especificas ninguna de las campañas involucradas en el experimento.
A continuación, se incluye una descripción general de algunos campos clave de un Experiment:
name: Cada experimento debe tener un nombre único.description: Es un campo opcional que puedes usar como referencia más adelante. No afecta la forma en que se ejecuta el experimento.suffix: El sufijo se agregará al final de los nombres de las campañas de tratamiento para que puedas distinguirlas de la campaña de control. Estos conceptos se explicarán con más detalle en el paso 2.type: Tipo de experimento que se ejecutará. Para los experimentos administrados por el sistema, usaSEARCH_CUSTOM,DISPLAY_CUSTOM,HOTEL_CUSTOM,YOUTUBE_CUSTOMoPMAX_REPLACEMENT_SHOPPING.status: Cuando crees un experimento, establece este campo enSETUP. Más adelante, cuando comiences el experimento, este campo te permitirá verificar el estado actual.start_dateyend_date: Especifica cuándo debe comenzar y finalizar el experimento.sync_enabled: Inhabilitado de forma predeterminada. Si se configura comotrue, los cambios realizados en la campaña original mientras se ejecuta el experimento se copian automáticamente en la campaña experimental. Más información.

2. Crea grupos experimentales
A continuación, crea recursos ExperimentArm para definir los grupos de control y tratamiento del experimento. Todos los brazos se deben crear en una sola solicitud.
Cada experimento debe tener exactamente un grupo de control y uno o más grupos de tratamiento. El grupo de control identifica la campaña de base para la comparación, y cada grupo de tratamiento genera una campaña nueva en la que puedes realizar cambios para probar.
También debes especificar traffic_split, que es el porcentaje de tráfico que se dirige a cada variante. La suma de las divisiones de tráfico en todos los grupos debe ser del 100.
Java

ExperimentArm.newBuilder() .setControl(true) .addCampaigns(ResourceNames.campaign(customerId, campaignId)) .setExperiment(experiment) .setName("control arm") .setTrafficSplit(40) .build()) .build()); operations.add( ExperimentArmOperation.newBuilder() .setCreate( // In standard campaign experiments, creating the treatment arm automatically // generates a draft campaign that you can modify before starting the experiment. ExperimentArm.newBuilder() .setControl(false) .setExperiment(experiment) .setName("experiment arm") .setTrafficSplit(60) .build()) .build()); try (ExperimentArmServiceClient experimentArmServiceClient = googleAdsClient.getLatestVersion().createExperimentArmServiceClient()) { // Constructs the mutate request.

MutateExperimentArmsResponse response = experimentArmServiceClient.mutateExperimentArms(mutateRequest); // Results always return in the order that you specify them in the request. Since we created // the treatment arm last, it will be the last result. If you don't remember which arm is the // treatment arm, you can always filter the query in the next section with // `experiment_arm.control = false`. MutateExperimentArmResult controlArmResult = response.getResults(0); MutateExperimentArmResult treatmentArmResult = response.getResults(response.getResultsCount() - 1); System.out.printf( "Created control arm with resource name '%s'%n", controlArmResult.getResourceName()); System.out.printf( "Created treatment arm with resource name '%s'%n", treatmentArmResult.getResourceName()); return treatmentArmResult.getExperimentArm().getInDesignCampaigns(0); } }

Algunos puntos clave:
- Exactamente un brazo debe tener
controlestablecido entrue. - El valor de
traffic_splitdebe sumar 100 en todos los grupos. - El grupo de control debe especificar exactamente una campaña en su campo
campaigns.
3. Cómo modificar campañas de tratamiento
Cuando creas un grupo de tratamiento (en el que control es false), la API crea automáticamente una campaña de borrador basada en la campaña de control y completa su nombre del recurso en el campo in_design_campaigns del grupo de tratamiento. Puedes tratar estas campañas en diseño como campañas normales y modificarlas con los cambios que desees probar. La campaña de control no se verá afectada. Estos cambios se materializan en una campaña real apta para publicarse cuando programas el experimento.
Se debe realizar al menos un cambio en una campaña en diseño antes de poder programar el experimento.
Para recuperar el in_design_campaigns de un grupo de tratamiento, puedes consultar GoogleAdsService:
SELECT experiment_arm.in_design_campaigns
FROM experiment_arm
WHERE experiment_arm.resource_name = "TREATMENT_ARM_RESOURCE_NAME"
Programa el experimento
Después de crear el experimento y los grupos, y de modificar los borradores de las campañas de tratamiento, puedes programar el experimento con ExperimentService.ScheduleExperiment. Esta es una operación asíncrona que materializa las campañas en diseño en campañas reales, listas para publicarse una vez que llegue el start_date del experimento. Consulta Errores asíncronos para obtener detalles sobre el manejo de operaciones de larga duración.
Genera un informe sobre el experimento
Una vez que se esté ejecutando el experimento, puedes consultar las métricas para comparar el rendimiento. Consulta la Guía de informes para obtener más detalles.
Finaliza, promueve o detén el experimento
Después de dejar que el experimento se ejecute durante un tiempo suficiente, puedes finalizarlo, promoverlo o graduarlo con ExperimentService.
- Finalizar: Si deseas detener el experimento sin aplicar cambios, usa
EndExperiment. Las campañas de tratamiento dejan de publicarse, pero no se quitan. Esta es una operación síncrona. - Promocionar: Si estás conforme con el rendimiento del grupo de tratamiento y deseas incorporar los cambios a tu campaña original, usa
PromoteExperiment. Esto copia los cambios del grupo de tratamiento a la campaña de control y detiene la publicación del grupo de tratamiento. Esta es una operación asíncrona. Consulta Errores asíncronos para obtener más detalles. Nota: No se pueden promocionar los experimentos de tipoPMAX_REPLACEMENT_SHOPPING. - Graduar: Si te gustaron los cambios, pero quieres que existan por separado de la campaña original, usa
GraduateExperiment. Esto convierte la campaña de tratamiento en una campaña estándar independiente que sigue publicándose fuera del contexto del experimento. La campaña de control no se modifica. Esta es una operación síncrona.
Requisitos específicos del tipo
PMAX_REPLACEMENT_SHOPPING
- Requiere exactamente dos grupos (uno de control y uno de tratamiento).
- El grupo de control debe especificar una campaña de Shopping en su campo
campaigns. - En el grupo de tratamiento, tienes dos opciones para configurar la campaña de máximo rendimiento:
- Para crear una campaña de máximo rendimiento nueva, deja el campo
campaignsdel grupo de tratamiento vacío. La API crea automáticamente una campaña integrada en el diseño basada en la campaña de Shopping de control, como se describe en el paso 3. - Para usar una campaña de máximo rendimiento existente, especifica el nombre del recurso de la campaña de máximo rendimiento en el campo
campaignsdel grupo de tratamiento. Si seleccionas esta opción, no se creará ninguna campaña integrada en el diseño y podrás omitir el paso 3.
- Para crear una campaña de máximo rendimiento nueva, deja el campo
- Se recomienda descartar las estadísticas de los primeros 7 días de tu evaluación para darle tiempo a la campaña de finalizar su período de adaptación y su fase de aprendizaje.
- No se puede promocionar.
YOUTUBE_CUSTOM
- Admite un máximo de 10 brazos.
- Para probar recursos, establece
creative_asset_testing_infoen el grupo experimental.
