出價調節係數

出價調整係數可讓您調整特定條件的出價，而不必變更廣告活動或廣告群組的指定目標。舉例來說，行動裝置的廣告群組出價調節係數不會排除其他裝置類型的曝光，但可讓您提高或降低行動曝光的出價。

修飾符會設為 bid_modifier 欄位的浮點調節係數。舉例來說，1.2 值會將出價調高 20%，而 0.8 值則會將出價調低 20%。如要排除裝置類型等支援的條件，請輸入 0.0 (相當於 Google Ads 使用者介面中的 -100% 出價調整幅度)，即可停用該條件。如果曝光適用多項出價調整幅度，系統會將這些調整幅度相乘，計算出最終出價調整幅度。如需有效值範圍，請參閱 CampaignBidModifier 和 AdGroupBidModifier 參考文件。

如要進一步瞭解出價的運作方式和如何設定出價調整係數，請參閱「出價總覽」和「管理出價調整係數」指南。

廣告活動出價調節係數

您可以使用 CampaignBidModifierService，在廣告活動層級為下列條件類型指定出價調整幅度：

InteractionTypeInfo
使用預先定義的 InteractionType 列舉定義 InteractionTypeInfo 條件。CALL 是廣告活動出價調整係數唯一支援的列舉值；指定任何其他值都會傳回 CriterionError。

廣告群組出價調節係數

您可以使用 AdGroupBidModifierService，在廣告群組層級為下列條件類型指定出價調整係數：

DeviceInfo
使用其中一個預先定義的 Device 列舉，定義 DeviceInfo 條件。
各種飯店廣告條件
為 HotelDateSelectionTypeInfo、HotelAdvanceBookingWindowInfo、HotelLengthOfStayInfo、HotelCheckInDayInfo 和 HotelCheckInDateRangeInfo 設定修飾符。詳情請參閱飯店廣告出價調節係數指南。

條件層級出價調節係數

除了專屬出價調節係數服務，在 CampaignCriterion 或 AdGroupCriterion 資源上設定的特定條件也支援直接設定 bid_modifier 欄位 (CampaignCriterion.bid_modifier 或 AdGroupCriterion.bid_modifier，例如位置、廣告時段或客層條件)。

程式碼範例

下列程式碼範例說明如何新增廣告群組層級的行動裝置出價調節係數：

Java

private void runExample(
    GoogleAdsClient googleAdsClient, long customerId, long adGroupId, double bidModifier) {

  // Creates an ad group bid modifier for mobile devices with the specified ad group ID and
  // bid modifier value.
  AdGroupBidModifier adGroupBidModifier =
      AdGroupBidModifier.newBuilder()
          .setAdGroup(ResourceNames.adGroup(customerId, adGroupId))
          .setBidModifier(bidModifier)
          .setDevice(DeviceInfo.newBuilder().setType(Device.MOBILE))
          .build();

  // Creates an ad group bid modifier operation for creating an ad group bid modifier.
  AdGroupBidModifierOperation adGroupBidModifierOperation =
      AdGroupBidModifierOperation.newBuilder().setCreate(adGroupBidModifier).build();

  // Issues a mutate request to add the ad group bid modifier.
  try (AdGroupBidModifierServiceClient adGroupBidModifierServiceClient =
      googleAdsClient.getLatestVersion().createAdGroupBidModifierServiceClient()) {
    MutateAdGroupBidModifiersResponse response =
        adGroupBidModifierServiceClient.mutateAdGroupBidModifiers(
            Long.toString(customerId), ImmutableList.of(adGroupBidModifierOperation));

    System.out.printf("Added %d ad group bid modifiers:%n", response.getResultsCount());
    for (MutateAdGroupBidModifierResult mutateAdGroupBidModifierResult :
        response.getResultsList()) {
      System.out.printf("\t%s%n", mutateAdGroupBidModifierResult.getResourceName());
    }
  }
}

                new AdGroupBidModifierOperation[] { adGroupBidModifierOperation });
        Console.WriteLine("Added {0} ad group bid modifiers:", response.Results.Count);
        foreach (MutateAdGroupBidModifierResult result in response.Results)
        {
            Console.WriteLine($"\t{result.ResourceName}");
        }
    }
    catch (GoogleAdsException e)
    {
        Console.WriteLine("Failure:");
        Console.WriteLine($"Message: {e.Message}");
