Cross-account Bidding Strategies

Cross-account bidding strategies are effectively Smart Bidding portfolio bidding strategies created in manager accounts. They can be used by campaigns in any client account beneath the manager that owns the strategy.

Create and manage

Creating a new cross-account bidding strategy is almost identical to creating a new portfolio bidding strategy, except you set the customer_id of the API call to that of a manager account. Use a manager account's ID to create a new BiddingStrategy resource, the same way you would create a new portfolio strategy in a client account.

Java

private String createBiddingStrategy(GoogleAdsClient googleAdsClient, long managerCustomerId) {
  try (BiddingStrategyServiceClient biddingStrategyServiceClient =
      googleAdsClient.getLatestVersion().createBiddingStrategyServiceClient()) {
    // Creates a portfolio bidding strategy.
    BiddingStrategy portfolioBiddingStrategy =
        BiddingStrategy.newBuilder()
            .setName("Maximize Clicks #" + getPrintableDateTime())
            .setTargetSpend(TargetSpend.getDefaultInstance())
            // Sets the currency of the new bidding strategy. If not provided, the bidding
            // strategy uses the manager account's default currency.
            .setCurrencyCode("USD")
            .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(managerCustomerId), ImmutableList.of(operation));

    // Prints the resource name of the created cross-account bidding strategy.
    MutateBiddingStrategyResult mutateBiddingStrategyResult = response.getResults(0);
    String resourceName = mutateBiddingStrategyResult.getResourceName();
    System.out.printf("Created cross-account bidding strategy: '%s'.%n", resourceName);

    return resourceName;

Set the currency code

Cross-account strategies in manager accounts support setting an optional currency_code, allowing them to share bidding strategies with client accounts in different currencies. The field is optional, and if not set will default to the manager account's currency. The currency_code field is only mutable on cross-account bidding strategies.

Java

BiddingStrategy portfolioBiddingStrategy =
    BiddingStrategy.newBuilder()
        .setName("Maximize Clicks #" + getPrintableDateTime())
        .setTargetSpend(TargetSpend.getDefaultInstance())

Update strategies

Some fields of a bidding strategy can be updated, depending on its type. Manager accounts that own a bidding strategy (or their managers) can update the fields of a coss-account bidding strategy similarly to any other portfolio strategy.

For example, to change the maximum bid limit for the TargetSpend strategy created in the previous example, set its cpc_bid_ceiling_micros field to a new value.

Remove unused strategies

To remove a cross-account bidding strategy, it must not be in use by any campaigns. Attempting to remove a strategy that is still in use will result in a CANNOT_REMOVE_ASSOCIATED_STRATEGY error. You must first remove the strategy from any associated campaigns.

Read attributes

The BiddingStrategy resource is used to create, update, and get properties of bidding strategies within a single account. As mentioned in the previous section, when that account is a manager, then mutating and reading from a BiddingStrategy resource manages cross-account bidding strategies.

Thus, when you are making API calls with a manager account, you can list and read its list of owned cross-account bidding strategies by querying the BiddingStrategy resource:

Java

private void listManagerOwnedBiddingStrategies(
    GoogleAdsClient googleAdsClient, long managerCustomerId) throws GoogleAdsException {
  try (GoogleAdsServiceClient googleAdsServiceClient =
      googleAdsClient.getLatestVersion().createGoogleAdsServiceClient()) {
    String query =
        "SELECT bidding_strategy.id, "
            + "bidding_strategy.name, "
            + "bidding_strategy.type, "
            + "bidding_strategy.currency_code "
            + "FROM bidding_strategy";
    // Constructs the SearchGoogleAdsStreamRequest.

            .setCustomerId(Long.toString(managerCustomerId))

            .build();

    // Creates and issues a search Google Ads stream request that will retrieve all bidding
    // strategies.
    ServerStream<SearchGoogleAdsStreamResponse> stream =
        googleAdsServiceClient.searchStreamCallable().call(request);

    // Iterates through and prints all of the results in the stream response.

View accessible bidding strategies

When working with client accounts that use cross-account bidding strategies, the AccessibleBiddingStrategy resource is used to provide a read-only view of all bidding strategies accessible to the current customer. This includes both portfolio strategies owned by the customer and cross-account bidding strategies shared with the customer.

Get all accessible bidding strategies

To retrieve all bidding strategies accessible by the current customer, query the accessible_bidding_strategy resource directly. The results will by default include both portfolio strategies in the current account and cross-account bidding strategies shared by a manager.

Get information about specific campaigns

You can also fetch fields of bidding_strategy and accessible_bidding_strategy when you query for campaigns. By using campaign in your query's FROM clause, the matching campaigns will implicitly join any associated bidding_strategy and accessible_bidding_strategy resources.

For example, the following query will fetch all active campaigns and fields of their associated bidding_strategy and accessible_bidding_strategy resources.

GAQL

SELECT campaign.id,
  campaign.name,
  campaign.bidding_strategy,
  campaign.bidding_strategy_type,
  accessible_bidding_strategy.id,
  accessible_bidding_strategy.name,
  accessible_bidding_strategy.type,
  accessible_bidding_strategy.owner_customer_id,
  accessible_bidding_strategy.owner_descriptive_name,
  bidding_strategy.name,
  bidding_strategy.type
FROM campaign
WHERE campaign.status != REMOVED

Attach to campaigns

Similar to standard portfolio bidding strategies, you attach a cross-account bidding strategy to a campaign by setting its bidding_strategy to the resource name of a cross-account bidding strategy. Only managers that own a cross-account bidding strategy (or managers of those managers) can attach them to campaigns. So API calls that attach cross-account bidding strategies to a campaign must use a login-customer-id of a manager that has the appropriate access to the bidding strategy.

    GoogleAdsClient googleAdsClient,

Remove bidding strategy

To disassociate a cross-account bidding strategy from a campaign, update the campaign to use a different bidding strategy. Either set its bidding_strategy field to use a different portfolio strategy or use a standard bidding strategy instead.

Unlink client account

If a client account is unlinked from its manager, any cross-account bidding strategies shared by that manager will no longer be accessible. Any of the client's campaigns set to use such a bidding strategy will stop serving and must be updated to use a different bidding strategy.

Portfolio and standard bidding strategies
