Campaign Budgets

Budgets are used to manage the amount of money spent for your AdWords campaigns. This guide describes everything you need to know to work with budgets in the AdWords API, including sharing, assigning, removing, and tracking the performance of budgets.

Sharing budgets

A budget can apply to a single campaign, or shared across many campaigns.

When you create a new Budget using the AdWords API, it's shareable by default. You can verify this by checking the value for isExplicitlyShared through an API call to the BudgetService:

  • isExplicitlyShared = true means the budget can be shared among multiple campaigns
  • isExplicitlyShared = false means the budget can be used by only one campaign

Explicitly shared budgets appear in an account's Shared Library in the AdWords user interface, whereas a non-shared budget appears only within its associated campaign's Settings.

In the following example that creates a new budget, the budget is shared because isExplicitlyShared is left at its default value of true.

Java

// Get the BudgetService.
BudgetServiceInterface budgetService =
    adWordsServices.get(session, BudgetServiceInterface.class);

// Create a budget, which can be shared by multiple campaigns.
Budget sharedBudget = new Budget();
sharedBudget.setName("Interplanetary Cruise #" + System.currentTimeMillis());
Money budgetAmount = new Money();
budgetAmount.setMicroAmount(50_000_000L);
sharedBudget.setAmount(budgetAmount);
sharedBudget.setDeliveryMethod(BudgetBudgetDeliveryMethod.STANDARD);

BudgetOperation budgetOperation = new BudgetOperation();
budgetOperation.setOperand(sharedBudget);
budgetOperation.setOperator(Operator.ADD);

// Add the budget
Long budgetId =
    budgetService.mutate(new BudgetOperation[] {budgetOperation}).getValue(0).getBudgetId();

C#

using (BudgetService budgetService =
    (BudgetService) user.GetService(AdWordsService.v201809.BudgetService))
{
    // Create the campaign budget.
    Budget budget = new Budget
    {
        name = "Interplanetary Cruise Budget #" + ExampleUtilities.GetRandomString(),
        deliveryMethod = BudgetBudgetDeliveryMethod.STANDARD,
        amount = new Money
        {
            microAmount = 500000
        }
    };

    BudgetOperation budgetOperation = new BudgetOperation
    {
        @operator = Operator.ADD,
        operand = budget
    };

    try
    {
        BudgetReturnValue budgetRetval = budgetService.mutate(new BudgetOperation[]
        {
            budgetOperation
        });

    End Try
End Using

Assigning a budget to a campaign

After you have created or identified a Budget with BudgetService, use the resulting budget ID in a subsequent call to CampaignService. Note that if the campaign operation fails but the budget operation succeeds, an orphaned budget (a budget associated with no campaign) will still be created. We recommend you either reuse or remove such budgets.

New campaign

For a new campaign, in the CampaignService.mutate() ADD operation, set the campaign's budget attribute to a Budget object with its budgetId set to the ID of a budget, as demonstrated in the code example below.

Java

// Get the CampaignService.
CampaignServiceInterface campaignService =
    adWordsServices.get(session, CampaignServiceInterface.class);

// Create campaign.
Campaign campaign = new Campaign();
campaign.setName("Interplanetary Cruise #" + System.currentTimeMillis());

// 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.
campaign.setStatus(CampaignStatus.PAUSED);

BiddingStrategyConfiguration biddingStrategyConfiguration = new BiddingStrategyConfiguration();
biddingStrategyConfiguration.setBiddingStrategyType(BiddingStrategyType.MANUAL_CPC);

// You can optionally provide a bidding scheme in place of the type.
ManualCpcBiddingScheme cpcBiddingScheme = new ManualCpcBiddingScheme();
biddingStrategyConfiguration.setBiddingScheme(cpcBiddingScheme);

campaign.setBiddingStrategyConfiguration(biddingStrategyConfiguration);

// You can optionally provide these field(s).
campaign.setStartDate(new DateTime().plusDays(1).toString("yyyyMMdd"));
campaign.setEndDate(new DateTime().plusDays(30).toString("yyyyMMdd"));
campaign.setFrequencyCap(new FrequencyCap(5L, TimeUnit.DAY, Level.ADGROUP));

// Only the budgetId should be sent, all other fields will be ignored by CampaignService.
Budget budget = new Budget();
budget.setBudgetId(budgetId);
campaign.setBudget(budget);

campaign.setAdvertisingChannelType(AdvertisingChannelType.SEARCH);

// Set the campaign network options to Search and Search Network.
NetworkSetting networkSetting = new NetworkSetting();
networkSetting.setTargetGoogleSearch(true);
networkSetting.setTargetSearchNetwork(true);
networkSetting.setTargetContentNetwork(false);
networkSetting.setTargetPartnerSearchNetwork(false);
campaign.setNetworkSetting(networkSetting);

// Set options that are not required.
GeoTargetTypeSetting geoTarget = new GeoTargetTypeSetting();
geoTarget.setPositiveGeoTargetType(GeoTargetTypeSettingPositiveGeoTargetType.DONT_CARE);
campaign.setSettings(new Setting[] {geoTarget});

// You can create multiple campaigns in a single request.
Campaign campaign2 = new Campaign();
campaign2.setName("Interplanetary Cruise banner #" + System.currentTimeMillis());
campaign2.setStatus(CampaignStatus.PAUSED);
BiddingStrategyConfiguration biddingStrategyConfiguration2 = new BiddingStrategyConfiguration();
biddingStrategyConfiguration2.setBiddingStrategyType(BiddingStrategyType.MANUAL_CPC);
campaign2.setBiddingStrategyConfiguration(biddingStrategyConfiguration2);

Budget budget2 = new Budget();
budget2.setBudgetId(budgetId);
campaign2.setBudget(budget2);

campaign2.setAdvertisingChannelType(AdvertisingChannelType.DISPLAY);

// Create operations.
CampaignOperation operation = new CampaignOperation();
operation.setOperand(campaign);
operation.setOperator(Operator.ADD);
CampaignOperation operation2 = new CampaignOperation();
operation2.setOperand(campaign2);
operation2.setOperator(Operator.ADD);

CampaignOperation[] operations = new CampaignOperation[] {operation, operation2};

// Add campaigns.

Replacing a campaign's budget

To replace the budget of an existing campaign, use a CampaignService.mutate() SET operation, and set the budget attribute of the campaign to a Budget object with its budgetId set to the ID of the existing budget (along with any other campaign fields that you might want to set). Note that this will replace the existing budget assigned to the campaign with the one specified by the budgetId, since a campaign can be associated with only one budget at a time.

Dissociating a budget from a campaign

A campaign must always be associated with a budget. You can remove a budget from a campaign by changing the ID of the budget associated with the campaign, thereby replacing it with another budget. To identify campaigns using a particular budget, see Retrieving the list of campaigns for a given Budget.

Removing a budget

Like campaigns, a budget cannot be completely deleted—you can only set its status to REMOVED.

Before removing a budget, ensure that no ENABLED or PAUSED campaigns are using it by checking its referenceCount. If this field is greater than 0, there are ENABLED or PAUSED campaigns still using the budget. You can retrieve the budget's referenceCount via a BudgetService.get() operation, or the referenceCount field from a CampaignService.get() operation.

Once you determine that a Budget is no longer used, send a BudgetOperation to BudgetService.mutate() with:

  • operator = SET
  • operand set to a Budget with:
    • budgetId set to the ID of the budget
    • status set to REMOVED

Additionally, you can remove a non-shared budget being used by a single campaign by removing that campaign. When you set the status of such a campaign to REMOVED, the status of its non-shared budget will also be set to REMOVED automatically.

Retrieving the list of campaigns for a given budget

Getting a list of campaigns that are using the same budget can be helpful when balancing budget utilization. The following AWQL query to CampaignService will return all campaigns for the specified budget ID:

SELECT Id WHERE BudgetId = <YOUR_BUDGET_ID>

Alternatively, you can use this AWQL statement to get the same information from the Campaign Performance Report:

SELECT CampaignId, BudgetId, IsBudgetExplicitlyShared, Impressions
FROM CAMPAIGN_PERFORMANCE_REPORT
WHERE BudgetId = <YOUR_BUDGET_ID>

Tracking performance

You can retrieve the budget performance stats for your campaigns using the Budget Performance Report, which includes all statistics aggregated by default at the budget level, one row per budget. If segment fields are used, you may get more than one row per budget. See segmentation for details.

Restrictions

Any campaign that has Campaign Experiments enabled must have its own non-shared budget.

Common Errors

Error Description
BudgetError.CANNOT_UPDATE_BUDGET_TO_IMPLICITLY_SHARED Indicates that you tried to set the isExplicitlyShared value of a budget from true to false in a SET operation. Once a budget is explicitly shared (isExplicitlyShared = true), you cannot change isExplicitlyShared back to false.
EntityCountLimitExceeded.ACCOUNT_LIMIT Indicates you've reached the maximum number of budgets in an account.
CampaignError.CAMPAIGN_CANNOT_USE_SHARED_BUDGET The campaign to which you're trying to add the budget is using campaign experiments, and the budget is already being used by another campaign.
BudgetError.CANNOT_EDIT_SHARED_BUDGET You're trying to modify the budget associated with a campaign using the CampaignService. You can only modify budgets via the BudgetService.
BudgetError.BUDGET_IN_USE You're trying to remove a budget associated with one or more active or paused campaigns.
