指定或更新出价策略

对于酒店广告，您可以为单个广告系列分配出价策略。

如需详细了解如何为酒店广告选择出价策略，请参阅酒店广告出价概览。熟悉出价策略后，您可以使用 Google Ads API 分配和更新酒店广告系列的出价策略。

分配出价策略

如需在制作新的酒店广告系列时分配策略，请按以下步骤操作：

选择 campaign_bidding_strategy。以下策略可用于酒店广告：
注意：请勿设置 bidding_strategy 或 bidding_strategy_type 字段。bidding_strategy_type 字段仅用于读取广告系列的当前设置；该字段是只读的。
确定要用于所选策略的字段名称-值对。
在制作新广告系列时设置策略。例如，在 Java 中，从 Campaign 实例的构建器内调用 campaign_bidding_strategy 字段的 setter 方法（方法名称惯例为 setcampaign_bidding_strategy）。

此示例演示了如何在制作新广告系列时设置 percent_cpc 出价策略：

Java

// Creates the campaign.
Campaign campaign =
    Campaign.newBuilder()
        .setName("Interplanetary Cruise #" + getPrintableDateTime())
        // Configures settings related to hotel campaigns including advertising channel type
        // and hotel setting info.
        .setAdvertisingChannelType(AdvertisingChannelType.HOTEL)
        .setHotelSetting(hotelSettingInfo)
        // Recommendation: Sets the campaign to PAUSED when creating it to prevent
        // the ads from immediately serving. Set to ENABLED once you've added
        // targeting and the ads are ready to serve
        .setStatus(CampaignStatus.PAUSED)
        // Sets the bidding strategy to Percent CPC. Only Manual CPC and Percent CPC can be used
        // for hotel campaigns.
        .setPercentCpc(
            PercentCpc.newBuilder().setCpcBidCeilingMicros(cpcBidCeilingMicroAmount).build())
        // Sets the budget.
        .setCampaignBudget(budgetResourceName)
        // Adds the networkSettings configured above.
        .setNetworkSettings(networkSettings)
        // Declares whether this campaign serves political ads targeting the EU.
        .setContainsEuPoliticalAdvertising(DOES_NOT_CONTAIN_EU_POLITICAL_ADVERTISING)
        .build();

C#

// Create a campaign.
Campaign campaign = new Campaign()
{
    Name = "Interplanetary Cruise Campaign #" + ExampleUtilities.GetRandomString(),

    // Configure settings related to hotel campaigns including advertising channel type
    // and hotel setting info.
    AdvertisingChannelType = AdvertisingChannelType.Hotel,
    HotelSetting = new HotelSettingInfo()
    {
        HotelCenterId = hotelCenterAccountId
    },

    // Recommendation: Set the campaign to PAUSED when creating it to prevent
    // the ads from immediately serving. Set to ENABLED once you've added
    // targeting and the ads are ready to serve.
    Status = CampaignStatus.Paused,

    // Sets the bidding strategy to PercentCpc. Only Manual CPC and Percent CPC can
    // be used for hotel campaigns.
    PercentCpc = new PercentCpc()
    {
        CpcBidCeilingMicros = cpcBidCeilingMicroAmount
    },

    // Set the budget.
    CampaignBudget = budgetResourceName,

    // Configure the campaign network options. Only Google Search is allowed for
    // hotel campaigns.
    NetworkSettings = new NetworkSettings()
    {
        TargetGoogleSearch = true
    },

    // Declare whether or not this campaign contains political ads targeting the EU.
    ContainsEuPoliticalAdvertising = EuPoliticalAdvertisingStatus.DoesNotContainEuPoliticalAdvertising,
};
