4.2 Criação de campanhas publicitárias

Introdução

---

Depois de concluir as etapas anteriores, permita que os comerciantes criem campanhas Performance Max de varejo e usem o aprendizado de máquina para tomar a decisão mais inteligente para veicular cada anúncio.

Para entender o que os anunciantes precisam fazer manualmente na IU do Google Ads para criar uma campanha Performance Max, consulte Criar uma campanha Performance Max. Nesta seção, descrevemos como usar a API Google Ads para permitir que seus anunciantes criem campanhas Performance Max que veiculam anúncios do Shopping.

Observação :se você ativou a opção de redirecionamento, nenhuma integração de API é necessária para a criação da campanha.

Nesta seção, abordamos somente as funcionalidades básicas de campanha que agregam mais valor para seus comerciantes, minimizando a complexidade de implementação. Para cada campanha, recomendamos fornecer as três opções de personalização a seguir aos seus comerciantes:

• Nome da campanha:como a campanha aparece nos relatórios.

• Orçamento:quanto a campanha deve gastar em média.

• Segmentação por área geográfica:onde a campanha deve veicular anúncios.

Observações sobre a segmentação por área geográfica:

• Essa funcionalidade é recomendada, mas opcional caso você queira reduzir ainda mais a complexidade de integração. Não está disponível na opção de redirecionamento.
• Se esse campo for omitido, os produtos serão veiculados em todos os países qualificados. Se um produto não puder ser veiculado em um determinado país (por exemplo, não atende aos requisitos de frete), ele será excluído da campanha automaticamente, sem que você precise fazer nada.

Além disso, no back-end, é necessário especificar mais alguns parâmetros, listados abaixo.

Estratégia de lances

A estratégia de lances automática define a meta da campanha ao definir lances. Para as campanhas Performance Max, há duas estratégias de lances disponíveis:

• Maximizar conversões: a campanha tenta maximizar o número de conversões alcançadas (por exemplo, o número de compras) para o orçamento especificado.

• Maximizar o valor da conversão (recomendado): a campanha tenta maximizar o valor monetário total das conversões (por exemplo, dinheiro gasto em compras) para o orçamento especificado, conforme você definiu como parte da configuração do acompanhamento de conversões.

Para simplificar a complexidade técnica e a experiência dos comerciantes, recomendamos que você selecione a estratégia "Maximizar o valor da conversão" em nome dos seus comerciantes, sem o ROAS desejado. Isso é consistente com o que está disponível por meio da opção de redirecionamento.

Grupos de recursos e de produtos anunciados

Os grupos de recursos são onde os elementos do criativo da campanha são armazenados, como produtos, imagens e vídeos. No pilar de fundação, apenas produtos do Merchant Center são abordados. Portanto, você só precisa de um único grupo de recursos por campanha, que pode ser criado no back-end em nome do comerciante.

Com os grupos de fichas, os comerciantes podem subdividir os produtos de uma campanha em grupos (por exemplo, para anunciar apenas produtos específicos). Esse é um recurso avançado não recomendado no pilar básico, mas toda campanha precisa ter pelo menos um grupo de fichas. Portanto, você só precisa de um único grupo de fichas por campanha, que pode ser criado no back-end em nome do comerciante.

Observação :o grupo de recursos substitui o que é chamado de grupo de anúncios em outros tipos de campanha (por exemplo, campanhas do Shopping). E um grupo de fichas substitui o que é chamado de grupo de produtos nas campanhas inteligentes do Shopping.

Orientação sobre UX

---

A primeira parte desta seção discute o cenário da criação da primeira campanha como parte do fluxo de integração do Google Ads. A segunda parte descreve como campanhas adicionais podem ser criadas. Isso é ainda mais relevante quando você permite que os comerciantes façam a segmentação geográfica das campanhas.

Criação de campanhas durante a integração do Google Ads

Depois de conectar a conta do Google Ads, o usuário precisa configurar uma campanha Performance Max:

• O nome da campanha pode ser preenchido previamente com um nome significativo, por exemplo, campanha Performance Max para o nome do criador de lojas.

• Também recomendamos incluir uma prévia da aparência de um anúncio e uma breve explicação de como as campanhas Performance Max funcionam. Como a API Google Ads não oferece uma maneira de gerar uma visualização, você teria que implementar uma. Não é necessário ter um pixel perfeito, já que o design do tipo de anúncio pode mudar.

• Se o comerciante estiver qualificado para um cupom, ele deverá ser mencionado na solicitação.

• Informe também um link para as políticas de anúncios do Shopping nesse ponto do fluxo.

• Você tem a opção de permitir que o comerciante segmente a campanha por área geográfica.

Dica :é melhor incluir apenas os países de destino disponíveis nos feeds de produtos do Merchant Center do comerciante.

Dois cenários são possíveis quando o comerciante chega à etapa de configuração da campanha:

1. O faturamento não está configurado. Isso sempre acontece quando uma nova conta do Google Ads é criada como parte desse fluxo.

2. O faturamento já está configurado para a conta do Google Ads conectada. Por exemplo, o comerciante reutilizou uma conta do Google Ads que já tinha usado para veicular outros tipos de campanhas.

Os cenários de faturamento corrompidos já devem ter sido identificados na etapa de vinculação da conta do Google Ads. A única diferença entre os cenários 1 e 2 é o comportamento e a call-to-action (CTA) da ação principal:

• No cenário 1, a CTA precisa ser chamada de "Configurar faturamento" e abrir o pop-up de faturamento. Depois que o faturamento for enviado e o pop-up for fechado, prossiga para a etapa "Revisar e concluir a configuração".

• No cenário 2, a CTA precisa ser chamada de "continuar" e prosseguir diretamente para a etapa "revisar e concluir a configuração".

Veja abaixo um exemplo de como a etapa de configuração da campanha pode ser para o cenário 1.

Outras informações precisam ser fornecidas ao comerciante sobre o nome da campanha, os produtos incluídos e o orçamento. Confira abaixo um exemplo de como isso pode ficar.

Se o comerciante inserir um orçamento abaixo do limite recomendado para o país em que ele anuncia, envie uma notificação com uma recomendação de orçamento mínimo. Confira abaixo uma sugestão de como isso pode ficar.

Depois de concluir a etapa de configuração da campanha e fornecer as informações de faturamento (se necessário), o usuário passa para a etapa de "revisão e conclusão". O usuário tem a oportunidade de revisar a configuração da campanha uma última vez antes de lançá-la. Nesta etapa, a interface vai ficar assim:

Após sair do fluxo de integração, recomendamos apresentar uma prévia ao usuário sobre o que acontece a seguir. Veja um exemplo abaixo.

Depois de sair da integração, o comerciante é direcionado para uma página de visão geral. Confira abaixo um exemplo de como isso pode ficar.

Campanhas de display e criação de campanhas adicionais

A interface precisa mostrar várias campanhas, já que os comerciantes podem ter campanhas Performance Max ou querem criar mais de uma, especialmente se você permitir a segmentação por área geográfica. Confira abaixo um exemplo de como permitir que um comerciante faça a segmentação geográfica das campanhas. Sempre garanta que a segmentação por área geográfica seja mais restrita do que o país ou os países em que o comerciante anuncia.

Quando um comerciante tiver mais de uma campanha, agregue as métricas de publicidade na página de visão geral. Confira abaixo um exemplo de como isso pode ficar.

Listar campanhas individuais na visualização de detalhes do Google Ads Confira abaixo um exemplo de como isso pode ficar.

A visualização de detalhes do Google Ads também é o ponto de partida sugerido para criar outras campanhas. Um exemplo de como esse fluxo pode ficar é mostrado na animação abaixo. A animação pula o preenchimento das informações de orçamento, já que essa parte é abordada anteriormente neste guia.

Orientação técnica

---

Depois de vincular a conta do Google Ads à do Merchant Center, crie a campanha Performance Max para varejo seguindo estas etapas:

1. Criar operação de orçamento
2. Criar operação de campanha
3. Criar critérios de campanha
4. Criar grupo de recursos com filtro de grupo de produtos anunciados
5. Substituir metas de conversão
6. Enviar todas as operações juntas

As seguintes condições se aplicam ao gerenciamento de campanhas Performance Max:

• É necessário usar pelo menos a versão 9 da API Google Ads

• Você deve enviar todas as operações mutate em uma única solicitação do tipo mutate. Portanto, primeiro você precisa criar todas as operações mutate e, em seguida, enviá-las todas juntas em uma única solicitação de mutação para a API Google Ads.

• Use IDs temporários em todas as operações que criar porque você envia uma única solicitação de mutação com todas as operações, e essas operações usam esses IDs temporários para informar ao Google que todos pertencem juntos.

Nome do conjunto

Se houver a possibilidade de os comerciantes acessarem a plataforma do Google Ads diretamente, avalie melhor o nome da campanha para que fique claro que você, o parceiro, a criou de maneira programática. Isso indica para o comerciante que é melhor fazer edições na campanha na sua plataforma, e não na do Google Ads. Por exemplo, mesmo que você permita que o comerciante personalize o nome, inclua "Created by platform X" antes ou depois do nome.

Dica :faça verificações para reduzir o risco de problemas fundamentais do Merchant Center e do Google Ads. Isso ajuda a preparar o comerciante para o sucesso. Consulte a seção 4.5 Tratamento de erros.

Etapa 1. Criar a operação de orçamento

O exemplo de código está disponível em Criar um orçamento de campanha. Portanto, aqui destacamos apenas os pontos mais importantes:

• Uma campanha Performance Max requer um orçamento, assim como todas as outras campanhas, mas com as seguintes restrições:

  • O orçamento deve ter um período orçamentário DIÁRIO.
  • O orçamento não pode ser compartilhado.

• O método de exibição do orçamento é "Padrão". A entrega padrão considera a performance esperada do anúncio ao longo do dia e é melhor para maximizar os resultados dentro do orçamento diário médio.

• Conforme mencionado anteriormente nesta seção, você precisa usar IDs temporários em todas as operações que criar. Portanto, é possível notar no exemplo de código que um _BUDGET_TEMPORARY_ID está definido no nome do recurso do orçamento para que possa ser referenciado pela campanha em etapas posteriores.

Etapa 2: Criar a campanha e a estratégia de lances

Consulte o exemplo de código em Criar a campanha e a estratégia de lances para saber como criar uma campanha Performance Max padrão. Aqui estão algumas observações adicionais:

• O exemplo de código usa a estratégia de lances Maximizar o valor da conversão, que é o que recomendamos no pilar de base. Com a estratégia "Maximizar o valor da conversão", você tem a opção de especificar um retorno do investimento em publicidade (ROAS) desejado. Mesmo que você opte por não especificar um valor de ROAS desejado, ainda precisa defini-lo, a menos que esteja usando Java. Em Java, você tem: setMaximizeConversionValue(MaximizeConversionValue.newBuilder().build())

• Para versões futuras, considere usar a estratégia Maximizar conversões como outra opção de estratégia de lances, com a capacidade de definir um CPA desejado.

• A expansão de URL permite que a campanha segmente todo o domínio, não apenas os URLs especificados no Merchant Center do anunciante. Recomendamos usar a expansão de URL final para que o alcance e a performance da campanha não sejam limitados. Isso significa que os anúncios podem ser veiculados em qualquer página do site do comerciante.

• start_date e end_date são opcionais.

Em uma campanha Performance Max para varejo, você também precisa criar uma ShoppingSetting com os campos a seguir e adicioná-la à campanha. Isso especifica qual conta do Merchant Center você quer usar, além do feed de produtos que será usado nessa conta. Conforme descrito em Criar uma campanha de varejo Performance Max, você precisa definir estes campos ShoppingSetting:

• merchant_id (obrigatório): o ID no Merchant Center da conta que contém os produtos a serem anunciados.

• feed_label (pode ser necessário): se houver um comerciante usando uma conta do Merchant Center com feeds de produtos antigos, use "feed_label" para especificar que você quer que a campanha use o feed de produtos que você criou. Ele é mapeado para DatafeedTarget na API Content.

Confira um exemplo de como criar uma campanha Performance Max para varejo e uma estratégia de lances. Isso pressupõe que há apenas um feed de produtos na conta do Merchant Center (ou seja, o que você gerencia) e, portanto, não define o feed_label.

Python
mutate_operation = googleads_client.get_type("MutateOperation")
campaign = mutate_operation.campaign_operation.create
campaign.name = f"Performance Max campaign #{uuid4()}"

campaign.status = googleads_client.enums.CampaignStatusEnum.ENABLED

campaign.advertising_channel_type = (       googleads_client.enums.AdvertisingChannelTypeEnum.PERFORMANCE_MAX
)

# Add Merchant Center ID to create a Performance Max for Retail
# campaign. This ID should be linked to the Ads account
# where you are creating the campaign
campaign.shopping_setting.merchant_id = int(google_merchant_id)
campaign.maximize_conversion_value.target_roas = None

# Set the Final URL expansion opt out. This option is specific to
# Performance Max campaigns. If opted out (True), only the
# final URLs in the asset group or URLs specified in the
# advertiser's Google Merchant Center or business data feeds are
# targeted.
# If opted in (False), the entire domain will be targeted.
# For best results, set this value to false to opt in and allow
# URL expansions. You can optionally add exclusions to limit
# traffic to parts of your website.
campaign.url_expansion_opt_out = False

# Assign the resource name with a temporary ID.
campaign_service = googleads_client.get_service("CampaignService")
campaign.resource_name = campaign_service.campaign_path(
       customer_id, _PERFORMANCE_MAX_CAMPAIGN_TEMPORARY_ID
)

# Set the budget using the given budget resource name.
campaign.campaign_budget = campaign_service.campaign_budget_path(
      customer_id, _BUDGET_TEMPORARY_ID
)

print("mutate_operation for step 2 - campaign and bidding strategy creation")
print(mutate_operation)

return mutate_operation

Etapa 3. Criar os critérios da campanha

Veja o exemplo de código em Criar os critérios da campanha. Portanto, estes são os pontos mais importantes:

• Como mostra o exemplo de código, primeiro você precisa iniciar todos os serviços necessários antes de prosseguir para configurar os critérios da campanha LOCATION e LANGUAGE.

• Ao definir os critérios da campanha LOCATION, você pode adicionar segmentações negativas para os locais que quer excluir configurando campaign_criterion.negative como "Verdadeiro".

• Use o mesmo ID temporário da etapa 2 para informar ao Google qual campanha você está criando esse critério.

Etapa 4. Criar o grupo de recursos com o filtro do grupo de produtos anunciados

Conforme descrito em Como criar grupos de recursos das campanhas Performance Max, um grupo é um conjunto de recursos centralizados em um tema ou relacionados a um público-alvo. O grupo de recursos é usado para criar todos os seus anúncios e um inventário para todos os formatos de anúncio aplicáveis ao seu objetivo publicitário.

É possível usar grupos de produtos anunciados do Shopping para particionar produtos em grupos e incluir um conjunto de produtos ou para excluí-los. Ela permite filtrar o conjunto de produtos qualificados para exibição na campanha.

Você pode ver o exemplo de código para criar vários grupos de produtos anunciados nos grupos de produtos anunciados das campanhas Performance Max. No entanto, para o pilar básico, é recomendável configurar uma única campanha que segmente todos os produtos de um comerciante. Portanto, incluímos abaixo um exemplo de código mais simples. É necessário incluir um nó AssetGroupListingGroupFilter raiz contendo todos os produtos. Caso contrário, os anúncios não serão veiculados.

Python
googleads_service = googleads_client.get_service("GoogleAdsService")

operations = []

# Create the AssetGroup
mutate_operation = googleads_client.get_type("MutateOperation")
asset_group = mutate_operation.asset_group_operation.create
asset_group.name = f"Performance Max asset group #{uuid4()}"
asset_group.campaign = googleads_service.campaign_path(
       customer_id, _PERFORMANCE_MAX_CAMPAIGN_TEMPORARY_ID
)

asset_group.status = googleads_client.enums.AssetGroupStatusEnum.ENABLED
asset_group.resource_name = googleads_service.asset_group_path(
      customer_id,
      _ASSET_GROUP_TEMPORARY_ID,
)
operations.append(mutate_operation)

# Create a listing group and link it to the AssetGroup.
# The way you link a listing group to an AssetGroup is different
# than when you are linking headlines, descriptions, images, etc
# where you set the field_type of the asset_group_asset as HEADLINE, for example.
# https://developers.google.com/google-ads/api/reference/rpc/v13/AssetGroupListingGroupFilter
mutate_operation = googleads_client.get_type("MutateOperation")
asset_group_listing_group = mutate_operation.asset_group_listing_group_filter_operation.create
asset_group_listing_group.asset_group = googleads_service.asset_group_path(
       customer_id,
       _ASSET_GROUP_TEMPORARY_ID,
)

asset_group_listing_group.type_ = googleads_client.enums.ListingGroupFilterTypeEnum.UNIT_INCLUDED
# here are other options for ListingGroupFilterTypeEnum
# https://developers.google.com/google-ads/api/reference/rpc/v13/ListingGroupFilterTypeEnum.ListingGroupFilterType

asset_group_listing_group.vertical = googleads_client.enums.ListingGroupFilterVerticalEnum.SHOPPING

operations.append(mutate_operation)

print("mutate_operation for step 4 - create asset group and product group attached to that asset group")
print(operations)

return operations

Você pode adicionar títulos, descrições e até imagens ao grupo de recursos para melhorar a performance da campanha. No entanto, como esse não é um requisito das campanhas Performance Max para varejo, não o recomendamos como pilar básico.

Etapa 5: Substituir metas de conversão

Conforme indicado na seção "Acompanhamento de conversões", se você permite que os comerciantes usem uma conta atual do Google Ads, é recomendável definir metas de conversão no nível da campanha. Para isso, substitua as metas de conversão no nível do cliente ou da conta. Quando nenhuma meta de conversão no nível da campanha é definida, o padrão da campanha é a meta de conversão no nível do cliente.

Um exemplo de código pode ser encontrado em Atualizar metas de conversão da campanha. Primeiro, é preciso ter as metas de conversão da conta. Em seguida, você pode iterar as metas de conversão e verificar se cada uma delas impulsiona as vendas on-line (ou seja, categoria PURCHASE, origem SITE). Se não for, defina a capacidade de lances como "False". Se for, defina a capacidade de lances como "True". Isso garante que a campanha Performance Max seja otimizada para aumentar as vendas on-line.

Etapa 6: Enviar todas as operações mutate juntas

Por fim, você deve enviar todas as operações mutate juntas. Conforme mostrado no exemplo de código abaixo, a ordem das operações é importante, porque elas dependem umas das outras. Por exemplo, performance_max_campaign_operation usa dados de campaign_budget_operation, e campaign_criterion_operations usa dados de performance_max_campaign_operation.

Python
ga_service = googleads_client.get_service("GoogleAdsService")
response = ga_service.mutate(
   customer_id=customer_id,
   mutate_operations=[
       # It's important to create the entities in this order
       # because they depend on each other
       campaign_budget_operation,       # Step 1
       performance_max_campaign_operation,  # Step 2
       # Expand the list of multiple operations into the list of
       # other mutate operations
       *campaign_criterion_operations,  # Step 3
       *asset_group_operations,             # Step 4
       *conversion_goal_operations,         # Step 5
   ],
)

Depois que a campanha é criada, a API retorna algo assim:

Python
mutate_operation_responses {
campaign_budget_result {
resource_name: "customers/7244690427/campaignBudgets/10689184019"
}
}
mutate_operation_responses {
campaign_result {
    resource_name: "customers/7244690427/campaigns/16822128600"
}
}
mutate_operation_responses {
campaign_criterion_result {
        resource_name: "customers/7244690427/campaignCriteria/16822128600~20009"
}
}
mutate_operation_responses {
    campaign_criterion_result {
resource_name: "customers/7244690427/campaignCriteria/16822128600~20024"
    }
}
mutate_operation_responses {
campaign_criterion_result {
        resource_name: "customers/7244690427/campaignCriteria/16822128600~1003"
    }
}
mutate_operation_responses {
asset_group_result {
        resource_name: "customers/7244690427/assetGroups/6444254998"
    }
}
mutate_operation_responses {
asset_group_listing_group_filter_result {
    resource_name: "customers/7244690427/assetGroupListingGroupFilters/6444254998~6454725458"
}
}
mutate_operation_responses {
campaign_conversion_goal_result {
    resource_name: "customers/7244690427/campaignConversionGoals/16822128600~PURCHASE~WEBSITE"
}
}

Salve o resource_name da campanha e do orçamento, porque você precisa deles ao editar as configurações da campanha e para gerar relatórios.

Resumo:confira exemplos abrangentes de código sobre como criar uma campanha Performance Max para varejo na seção Exemplos de código da documentação da API Ads. Esses exemplos podem incluir instruções para implementar recursos além do recomendado nos pilares básicos, incluindo a adição de outros recursos de título e imagem.

/**
 * This example shows how to create a Performance Max retail campaign.
 *
 * This will be created for "All products".
 *
 * For more information about Performance Max retail campaigns, see
 * https://developers.google.com/google-ads/api/docs/performance-max/retail.
 *
 * Prerequisites:
 * - You need to have access to a Merchant Center account. You can find
 * instructions to create a Merchant Center account here:
 * https://support.google.com/merchants/answer/188924.
 * This account must be linked to your Google Ads account. The integration
 * instructions can be found at:
 * https://developers.google.com/google-ads/api/docs/shopping-ads/merchant-center
 * - You need your Google Ads account to track conversions. The different ways
 * to track conversions can be found here:
 * https://support.google.com/google-ads/answer/1722054.
 * - You must have at least one conversion action in the account. For more about conversion
 * actions, see
 * https://developers.google.com/google-ads/api/docs/conversions/overview#conversion_actions.

"""This example shows how to create a Performance Max retail campaign.

This will be created for "All products".

For more information about Performance Max retail campaigns, see
https://developers.google.com/google-ads/api/docs/performance-max/retail

Prerequisites:
- You need to have access to a Merchant Center account. You can find
  instructions to create a Merchant Center account here:
  https://support.google.com/merchants/answer/188924.
  This account must be linked to your Google Ads account. The integration
  instructions can be found at:
  https://developers.google.com/google-ads/api/docs/shopping-ads/merchant-center
- You need your Google Ads account to track conversions. The different ways
  to track conversions can be found here:
  https://support.google.com/google-ads/answer/1722054.
- You must have at least one conversion action in the account. For
  more about conversion actions, see
  https://developers.google.com/google-ads/api/docs/conversions/overview#conversion_actions

#
# For more information about Performance Max retail campaigns, see
# https://developers.google.com/google-ads/api/docs/performance-max/retail
#
# Prerequisites:
# - You need to have access to a Merchant Center account. You can find
#   instructions to create a Merchant Center account here:
#   https://support.google.com/merchants/answer/188924.
#   This account must be linked to your Google Ads account. The integration
#   instructions can be found at:
#   https://developers.google.com/google-ads/api/docs/shopping-ads/merchant-center
# - You need your Google Ads account to track conversions. The different ways
#   to track conversions can be found here:
#   https://support.google.com/google-ads/answer/1722054.
# - You must have at least one conversion action in the account. For
#   more about conversion actions, see
#   https://developers.google.com/google-ads/api/docs/conversions/overview#conversion_actions

# This example shows how to create a Performance Max retail campaign.
#
# This will be created for "All products".
#
# For more information about Performance Max retail campaigns, see
# https://developers.google.com/google-ads/api/docs/performance-max/retail.
#
# Prerequisites:
# - You need to have access to a Merchant Center account. You can find
#   instructions to create a Merchant Center account here:
#   https://support.google.com/merchants/answer/188924.
#   This account must be linked to your Google Ads account. The integration
#   instructions can be found at:
#   https://developers.google.com/google-ads/api/docs/shopping-ads/merchant-center.
# - You need your Google Ads account to track conversions. The different ways
#   to track conversions can be found here:
#   https://support.google.com/google-ads/answer/1722054.
# - You must have at least one conversion action in the account. For more about
#   conversion actions, see
#   https://developers.google.com/google-ads/api/docs/conversions/overview#conversion_actions.

Status de veiculação da campanha:para que a campanha seja exibida, pelo menos um produto precisa ser aprovado no Merchant Center. Caso contrário, o status da campanha mostrará que ela está em exibição, mas, na realidade, não está.

Solução de problemas:faça login na plataforma do Google Ads como a conta de administrador. Acesse a campanha Performance Max de uma subconta e verifique as configurações dela. Também pode ser útil consultar o histórico de alterações para confirmar se foi você que fez as mudanças usando a API Ads.
