Depois de criar um experimento, é necessário criar vários grupos experimentais para que ele tenha mais informações sobre o que exatamente está testando.
Grupos experimentais
O ExperimentArm
representa uma parte da
comparação que você está fazendo para o experimento. Todos os experimentos precisam sempre
ter exatamente um grupo de controle. Esse grupo é uma campanha atual que forma
a base para comparar com o outro.
Os outros grupos são chamados de grupos de tratamento e, neles, você faz alterações na campanha antes de iniciar o experimento.
O ExperimentArm
também contém a configuração traffic_split
. Assim, você pode
especificar a porcentagem de tráfego direcionado para cada grupo do
experimento. Cada grupo precisa especificar uma divisão de tráfego, e a soma dos valores da divisão de tráfego em todos eles precisa somar 100.
Devido a essa restrição de divisão de tráfego, todos os grupos experimentais precisam ser criados na mesma solicitação.

Alguns pontos importantes sobre o exemplo acima:
- O
name
de cada grupo precisa ser exclusivo noExperiment
. - O
traffic_split
precisa somar 100 em todos os grupos. Exatamente um grupo precisa ter
control
definido comotrue
. Todos os outros grupos precisam ter a definição comofalse
.Somente o grupo de controle especifica uma matriz
campaigns
que contém apenas uma campanha.
Grupos de tratamento
Depois de criar todos os grupos experimentais, os grupos de tratamento (aqueles em que control
está definido como false
) preenchem automaticamente o campo in_design_campaigns
. Para recuperar o campo da resposta da API, defina o tipo de conteúdo da resposta como MUTABLE_RESOURCE
, como no exemplo de código. Também é possível buscá-lo usando uma
consulta GoogleAdsService
:
SELECT experiment_arm.in_design_campaigns
FROM experiment_arm
WHERE experiment_arm.resource_name = "TREATMENT_ARM_RESOURCE_NAME"
Campanhas com design
Você pode tratar essas campanhas com design como campanhas normais. Faça as alterações que você quer testar no experimento nessas campanhas. A campanha de controle não será afetada. Depois de programar o experimento, essas alterações são materializadas em uma campanha real que pode veicular anúncios.
Tecnicamente, essas campanhas com foco no design são rascunhos. Para encontrá-los em GoogleAdsService
, adicione o parâmetro include_drafts=true
à consulta.
É preciso fazer pelo menos uma alteração na campanha com design antes de programar o experimento.
