4.2 広告キャンペーンの作成

はじめに


上記の手順を完了すると、販売者が P-MAX 小売キャンペーンを作成して、機械学習を活用して各広告の配信について最適な判断を下せるようになります。

Google 広告管理画面で P-MAX キャンペーンを作成するために広告主様が手動で行う必要がある作業については、P-MAX キャンペーンを作成するをご覧ください。このセクションでは、Google Ads API を使用して、広告主様がショッピング広告を配信する P-MAX キャンペーンを作成できるようにする方法について説明します。

このセクションでは、実装の複雑さを最小限に抑えながら販売者に最大限の価値をもたらす、キャンペーンの基本機能のみについて説明します。キャンペーンごとに、販売者に次の 3 つのカスタマイズ オプションを提供することをおすすめします。

  • キャンペーン名: レポートに表示されるキャンペーンの名前。

  • 予算: キャンペーンで平均的に支出する金額。

  • 地域ターゲティング: キャンペーンで広告を配信する地域。

また、バックエンドで、次のパラメータをいくつか指定する必要があります。

入札戦略

自動入札戦略では、入札単価を設定する際にキャンペーンで最大化される目標を定義します。P-MAX では、次の 2 つの入札戦略を使用できます。

  • コンバージョン数の最大化: 指定した予算内でコンバージョン数(購入数など)を最大化するようにキャンペーンが設定されます。

  • コンバージョン値の最大化(推奨): コンバージョン トラッキング設定の一部として定義した予算内で、コンバージョンの合計金額(購入に費やされた金額など)を最大化するようにキャンペーンが設定されます。

技術的な複雑さを軽減し、販売者の操作を簡素化するために、目標広告費用対効果を設定せずに、販売者の代わりに「コンバージョン値の最大化」を選択することをおすすめします。これは、リダイレクト オプションで使用できるものと一致します。

アセット グループとリスティング グループ

アセット グループは、キャンペーンのクリエイティブ要素(商品、画像、動画など)を保存する場所です。基盤となるピラーでは、Merchant Center の商品のみが対象となります。そのため、キャンペーンごとに必要なアセット グループは 1 つだけです。このアセット グループは、販売者を代理してバックエンドで作成できます。

リスティング グループを使用すると、キャンペーン内の商品をグループに分割できます(特定の商品のみを宣伝する場合など)。これは高度な機能であり、基本的な要素では推奨されませんが、すべてのキャンペーンに少なくとも 1 つのリスティング グループが必要です。したがって、キャンペーンごとに必要なリスティング グループは 1 つだけです。これは、販売者様に代わってバックエンドで作成できます。

UX ガイダンス


このセクションの最初の部分では、Google 広告のオンボーディング フローの一部として最初のキャンペーンを作成するシナリオについて説明します。2 番目のパートでは、追加のキャンペーンを作成する方法について説明します。これは、販売者がキャンペーンの地理的なターゲティングを許可している場合に特に重要です。

Google 広告のオンボーディング中のキャンペーン作成

Google 広告アカウントをリンクすると、P-MAX キャンペーンの設定を求めるメッセージが表示されます。

  • キャンペーン名には、ストアビルダー名の P-MAX キャンペーンなど、わかりやすい名前を事前に入力できます。

  • また、広告のプレビューと、P-MAX キャンペーンの仕組みに関する簡単な説明も含めることをおすすめします。Google Ads API には広告プレビューを生成する方法がないため、自分で実装する必要があります。広告フォーマットのデザインが変更される可能性があるため、ピクセル単位で正確に作成する必要はありません。

  • 販売者がクーポンの対象となる場合は、プロンプトにその旨を記載する必要があります。

  • この時点で、ショッピング広告のポリシーへのリンクも必ず提供してください。

  • 必要に応じて、販売者がキャンペーンの地域ターゲティングを許可することもできます。

販売者がキャンペーンの設定手順に進んだ場合、次の 2 つのシナリオが考えられます。

  1. お支払い情報が設定されていません。このフローの一環として新しい Google 広告アカウントが作成された場合は、常にこのようになります。

  2. リンクされた Google 広告アカウントのお支払い情報がすでに設定されている(たとえば、販売者が他のタイプのキャンペーンの実施に使用した Google 広告アカウントを再利用している場合)。

請求に関する問題のあるシナリオは、Google 広告アカウントのリンク手順ですでに検出されているはずです。シナリオ 1 と 2 の唯一の違いは、メイン アクションの動作と行動を促すフレーズ(CTA)です。

  • シナリオ 1 では、CTA は「お支払い情報を設定」という名前で、お支払い情報のポップアップを開きます。お支払い情報を入力してポップアップを閉じたら、[確認して設定を完了] の手順に進みます。

  • シナリオ 2 では、CTA は「続行」と呼ばれ、[設定を確認して完了] ステップに直接進む必要があります。

シナリオ 1 のキャンペーン設定ステップの例を以下に示します。

pmax

キャンペーン名、対象商品、予算に関する追加情報を販売者に提供する必要があります。以下に例を示します。

pmax2

販売者が広告を掲載する国で推奨されるしきい値を下回る予算を入力した場合は、推奨される最低予算額を通知します。以下に、この方法の例を示します。

billig

キャンペーンの設定手順を完了し、お支払い情報を入力したら(必要に応じて)、[確認して完了] 手順に進みます。キャンペーンを開始する前に、キャンペーンの設定をもう一度確認できます。このステップの UI は次のようになります。

pmax3

オンボーディング フローを終了した後、次の手順のプレビューをユーザーに表示することをおすすめします。たとえば、次のようになります。

first_campaign

オンボーディングを終了すると、概要ページに移動します。以下に例を示します。

概要

ディスプレイ キャンペーンと追加のキャンペーンを作成する

販売者は既存の P-MAX キャンペーンを持っている場合や、複数のキャンペーンを作成する場合があります(特に地域ターゲティングを許可している場合)。そのため、UI では複数のキャンペーンを表示できるようにする必要があります。販売者がキャンペーンの地域ターゲティングを許可する例を以下に示します。地域ターゲティングは、販売者が広告を掲載する国よりも狭く設定してください。

pmax4

販売者が複数のキャンペーンを運用している場合は、概要ページで広告指標を集計します。以下に例を示します。

pmax4

Google 広告の詳細ビューで個々のキャンペーンを一覧表示します。以下に例を示します。

詳細

Google 広告の詳細ビューは、追加のキャンペーンを作成する際の出発点としても推奨されます。このフローの例を次のアニメーションに示します。このアニメーションでは、予算情報の入力はスキップされています。この部分については、このガイドの前半で説明しています。

技術ガイダンス


Google 広告アカウントを Merchant Center アカウントにリンクしたら、次の手順で小売店向け P-MAX キャンペーンを作成できます。

  1. 予算オペレーションを作成する
  2. キャンペーン作成オペレーション
  3. キャンペーン条件を作成する
  4. リスティング グループのフィルタを使用してアセット グループを作成する
  5. コンバージョン目標をオーバーライドする
  6. すべてのオペレーションを一緒に送信する

P-MAX キャンペーンの管理には、次の点にご注意ください。

  • Google Ads API のバージョン 9 以降を使用している必要があります

  • すべてのミューテーション オペレーションを 1 つのミューテーション リクエストで送信する必要があります。そのため、まずすべての変更オペレーションを作成し、それらをすべて 1 つの変更リクエストで Google Ads API に送信する必要があります。

  • 作成するすべてのオペレーションで一時 ID を使用するのは、すべてのオペレーションを含む単一のミューテーション リクエストを送信するためです。これらのオペレーションは、一時 ID を使用して、すべてが一緒に属していることを Google に通知します。

名前を設定

販売者が Google 広告プラットフォームに直接アクセスする可能性がある場合は、キャンペーン名を慎重に選択し、パートナーがプログラムによってキャンペーンを作成したことを明確にする必要があります。これにより、Google 広告プラットフォームではなく、貴社のプラットフォームからキャンペーンを編集することを販売者におすすめできます。たとえば、販売者が名前をカスタマイズできるようにしても、名前の前に「プラットフォーム X によって作成」を追加したり、名前の後に追加したりすることをおすすめします。

ステップ 1. 予算オペレーションを作成する

コードサンプルはキャンペーン予算を作成するで確認できます。ここでは、最も重要なポイントのみを紹介します。

  • P-MAX キャンペーンでは、他のキャンペーンと同様に予算が必要ですが、次の制限があります。

    • 予算の期間は 1 日単位である必要があります。
    • 予算を共有することはできません。
  • 予算の配信方法は「標準」です。[標準の広告配信] では、1 日に見込まれる広告の掲載結果を考慮した配信が行われるため、1 日の平均予算内で成果を最大化するには [広告配信の集中化] の場合よりも効果的です。

  • このセクションで説明したように、作成するすべてのオペレーションで一時 ID を使用する必要があります。そのため、コードサンプルでは、予算のリソース名に _BUDGET_TEMPORARY_ID が設定されており、後続のステップでキャンペーンから参照できるようにしています。

ステップ 2. キャンペーンと入札戦略を作成する

標準の P-MAX キャンペーンを作成する方法については、キャンペーンと入札戦略を作成するのコードサンプルをご覧ください。その他の注意事項は次のとおりです。

  • このコードサンプルでは、入札戦略に「コンバージョン値の最大化」を使用しています。これは、基盤の柱で使用することをおすすめする入札戦略です。「コンバージョン値の最大化」では、目標広告費用対効果(ROAS)を指定できます。目標広告費用対効果の値を指定しない場合でも、Java を使用している場合を除き、設定する必要があります。Java では、次のようになります。 setMaximizeConversionValue(MaximizeConversionValue.newBuilder().build())

  • 今後のバージョンでは、目標コンバージョン単価を設定できる別の入札戦略として「コンバージョン数の最大化」の使用を検討してください。

  • URL の展開機能を使用すると、広告主様の Merchant Center で指定された URL だけでなく、ドメイン全体をキャンペーンのターゲットに設定できます。キャンペーンのリーチと最終的なパフォーマンスが制限されないように、最終ページ URL の拡張を使用することをおすすめします。販売者のウェブサイトの任意のページに広告が配信される可能性があります。

  • start_dateend_date は省略可能です。

小売店向け P-MAX キャンペーンの場合は、次のフィールドを含む ShoppingSetting を作成してキャンペーンに追加する必要があります。ここでは、使用する Merchant Center アカウントと、そのアカウントで使用する商品フィードを指定する。P-MAX 小売キャンペーンを作成するで説明されているように、次の ShoppingSetting フィールドを設定する必要があります。

  • merchant_id(必須): 宣伝する商品を含むアカウントの Merchant Center ID。

  • feed_label(必須ではない): 古い商品フィードを含む既存の Merchant Center アカウントを使用している販売者が存在する可能性がある場合は、feed_label を使用して、作成した商品フィードを使用するようにキャンペーンに指定する必要があります。これは、Content API の DatafeedTarget に対応しています。

小売向けの P-MAX キャンペーンと入札戦略を作成する手順の例を以下に示します。これは、Merchant Center アカウントに商品フィードが 1 つしかない(つまり、管理している商品フィードのみ)ことを前提としており、feed_label は設定されません。

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

ステップ 3. キャンペーン条件を作成する

コードサンプルについては、キャンペーン条件を作成するをご覧ください。ここでは、最も重要なポイントを紹介します。

  • コードサンプルに示すように、キャンペーン条件の LOCATION と LANGUAGE の設定に進む前に、まず必要なすべてのサービスを開始する必要があります。

  • 地域のキャンペーン条件を設定するときに、campaign_criterion.negative を true に設定すると、除外する地域の除外ターゲットを追加できます。

  • ステップ 2 と同じ一時 ID を使用して、この条件を作成するキャンペーンを Google に伝えてください。

ステップ 4. リスティング グループのフィルタを使用してアセット グループを作成する

P-MAX アセット グループの作成で説明したように、アセット グループは、1 つのテーマを中心とする、またはターゲット オーディエンスに関連するアセットの集まりです。アセット グループは、広告の作成と、広告目標で使用可能なすべての広告フォーマットの広告枠の作成に使用されます。

ショッピング リスティング グループを使用すると、商品をグループに分割して、一連の商品を含めるか除外することができます。キャンペーンに表示する商品のセットをフィルタできます。

複数の商品リスティング グループを作成するコードサンプルについては、P-MAX リスティング グループをご覧ください。ただし、基盤の柱では、販売者のすべての商品をターゲットとする単一のキャンペーンを設定することをおすすめします。そのため、よりシンプルなコードサンプルを以下に示します。すべてのプロダクトを含むルート AssetGroupListingGroupFilter ノードを含める必要があります。有効な広告がない場合は、広告は配信されません。

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

アセット グループに広告見出し、説明文、画像を追加して、キャンペーンのパフォーマンスを高めることができます。ただし、これは小売向け P-MAX の要件ではないため、基盤の柱ではおすすめしません。

ステップ 5. コンバージョン目標を上書きする

コンバージョン トラッキングのセクションで説明したように、販売者が既存の Google 広告アカウントを使用できるようにする場合は、キャンペーン単位でコンバージョン目標を設定することを強くおすすめします。これは、顧客単位またはアカウント単位でコンバージョン目標をオーバーライドすることで行えます。キャンペーン単位のコンバージョン目標が設定されていない場合、キャンペーンはデフォルトで顧客単位のコンバージョン目標を使用します。

コードサンプルについては、キャンペーンのコンバージョン目標を更新するをご覧ください。まず、アカウントのコンバージョン目標を取得します。次に、コンバージョン目標を反復処理し、各目標がオンライン販売の促進(カテゴリが「購入」、参照元が「ウェブサイト」)を目的としているかどうかを確認します。そうでない場合は、入札可能を False に設定します。有効な場合は、入札可能を True に設定します。これにより、オンライン販売の増加を目的として P-MAX キャンペーンが最適化されます。

ステップ 6. すべてのミューテーション オペレーションを一緒に送信する

最後に、すべてのミューテーション オペレーションをまとめて送信する必要があります。以下のコードサンプルに示すように、オペレーションは相互に依存するため、オペレーションの順序は重要です。たとえば、performance_max_campaign_operationcampaign_budget_operation のデータを使用し、campaign_criterion_operationsperformance_max_campaign_operation のデータを使用します。

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
   ],
)

キャンペーンが正常に作成されると、API から次のようなレスポンスが返されます。

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"
}
}

キャンペーンと予算の resource_name を保存します。これは、キャンペーン設定の編集時やレポート作成時に必要になります。

 * 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

"""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

# 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.
