Portfolio and Standard Bidding Strategies

Portfolio bidding strategies are automated, goal-driven bidding strategies that can be shared among multiple campaigns, whereas standard bidding strategies are not shared and can only be used by a single campaign. The API supports creating both types of strategies. Portfolio bidding strategies are created as standalone objects in an account, whereas standard strategies are managed by setting appropriate fields on a campaign.

Portfolio bidding strategies

To use a portfolio bidding strategy with your campaign, you have two options:

  1. Use an existing BiddingStrategy.
  2. Use MutateBiddingStrategies to create a new one with the fields name and scheme set. As an example, for an ENHANCED_CPC bidding strategy, set the field enhanced_cpc with a new object typed as EnhancedCpc.

Once you've chosen a BiddingStrategy, configure your campaign to use it by setting the campaign's bidding_strategy field to its resource_name.

The following example demonstrates how to create a new portfolio ENHANCED_CPC bidding strategy for a new campaign.

Java

private String createBiddingStrategy(GoogleAdsClient googleAdsClient, long customerId) {
  try (BiddingStrategyServiceClient biddingStrategyServiceClient =
      googleAdsClient.getLatestVersion().createBiddingStrategyServiceClient()) {
    // Creates a portfolio bidding strategy.
    TargetSpend targetSpend = TargetSpend.newBuilder().setCpcBidCeilingMicros(2_000_000L).build();
    BiddingStrategy portfolioBiddingStrategy =
        BiddingStrategy.newBuilder()
            .setName("Maximize Clicks #" + getPrintableDateTime())
            .setTargetSpend(targetSpend)
            .build();
    // Constructs an operation that will create a portfolio bidding strategy.
    BiddingStrategyOperation operation =
        BiddingStrategyOperation.newBuilder().setCreate(portfolioBiddingStrategy).build();
    // Sends the operation in a mutate request.
    MutateBiddingStrategiesResponse response =
        biddingStrategyServiceClient.mutateBiddingStrategies(
            Long.toString(customerId), Lists.newArrayList(operation));

    MutateBiddingStrategyResult mutateBiddingStrategyResult = response.getResults(0);
    // Prints the resource name of the created object.
    System.out.printf(
        "Created portfolio bidding strategy with resource name: '%s'.%n",
        mutateBiddingStrategyResult.getResourceName());

    return mutateBiddingStrategyResult.getResourceName();
  }
}
      

C#

private string CreatePortfolioBiddingStrategy(GoogleAdsClient client,
    long customerId, string name, long bidCeiling)
{
    // Get the BiddingStrategyService.
    BiddingStrategyServiceClient biddingStrategyService = client.GetService(
        Services.V12.BiddingStrategyService);

    // Create a portfolio bidding strategy.
    BiddingStrategy biddingStrategy = new BiddingStrategy()

        Name = name,

        TargetSpend = new TargetSpend()
        {
            CpcBidCeilingMicros = bidCeiling,
        }
    };

    // Create operation.
    BiddingStrategyOperation biddingOperation = new BiddingStrategyOperation()
    {
        Create = biddingStrategy
    };

    // Create the portfolio bidding strategy.
    MutateBiddingStrategiesResponse biddingResponse =
        biddingStrategyService.MutateBiddingStrategies(

An existing portfolio bidding strategy can be linked to a shared budget. Once the two are associated, the shared budget will always be associated with the campaigns that are part of the bidding strategy.

You can only link together a portfolio bidding strategy and an existing shared budget—you cannot create one of the two and immediately associate it with the other.

To associate a BiddingStrategy with a CampaignBudget, send a MutateOperation that updates the two entities, setting the aligned_budget_id field in the bidding strategy to the ID of the shared budget and the aligned_bidding_strategy field in the campaign budget to the ID of the portfolio bidding strategy.

Standard bidding strategies

To use a standard bidding strategy with your campaign, set the campaign as follows:

This example demonstrates how to set a standard MAXIMIZE_CONVERSION_VALUE bidding strategy when creating a new campaign:

Java

/** Creates a MutateOperation that creates a new Performance Max campaign. */
private MutateOperation createPerformanceMaxCampaignOperation(long customerId) {
  Campaign performanceMaxCampaign =
      Campaign.newBuilder()
          .setName("Performance Max campaign #" + getPrintableDateTime())
          // Sets the campaign status as PAUSED. The campaign is the only entity in
          // the mutate request that should have its status set.
          .setStatus(CampaignStatus.PAUSED)
          // All Performance Max campaigns have an advertising_channel_type of
          // PERFORMANCE_MAX. The advertising_channel_sub_type should not be set.
          .setAdvertisingChannelType(AdvertisingChannelType.PERFORMANCE_MAX)
          // Bidding strategy must be set directly on the campaign.
          // Setting a portfolio bidding strategy by resource name is not supported.
          // Max Conversion and Maximize Conversion Value are the only strategies
          // supported for Performance Max campaigns.
          // An optional ROAS (Return on Advertising Spend) can be set for
          // maximize_conversion_value. The ROAS value must be specified as a ratio in
          // the API. It is calculated by dividing "total value" by "total spend".
          // For more information on Maximize Conversion Value, see the support
          // article: http://support.google.com/google-ads/answer/7684216.
          // A targetRoas of 3.5 corresponds to a 350% return on ad spend.
          .setMaximizeConversionValue(
              MaximizeConversionValue.newBuilder().setTargetRoas(3.5).build())
          // Sets the Final URL expansion opt out. This flag 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
