Google Ads transfers
The BigQuery Data Transfer Service for Google Ads connector (formerly known as Google AdWords) lets you automatically schedule and manage recurring load jobs for Google Ads reporting data.
Supported reports
The BigQuery Data Transfer Service for Google Ads supports Google Ads API v16:
For information about how Google Ads reports are transformed into BigQuery Data Transfer Service tables and views, see Google Ads report transformations.
To map Google Ads reports to what you see in the Google Ads UI, see Mapping reports to the Google Ads UI.
Reporting option | Support |
---|---|
Supported API version | |
Repeat frequency | Daily, at the time the data transfer is first created (default) You can configure the time of day. |
Refresh window | Last 7 days (default) Configurable up to 30 days Snapshots of Match Tables are taken once a day and stored in the partition for the last run date. Match Table snapshots are not updated for backfills or for days loaded using the refresh window. |
Maximum backfill duration | No limit While Google Ads has no known data retention limits except Click Performance Report, the BigQuery Data Transfer Service has limits on how many days can be requested in a single backfill. For information about backfills, see Manually trigger a transfer. |
Number of Customer IDs per manager account | 8,000 The BigQuery Data Transfer Service supports a maximum of 8000 Customer IDs for each Google Ads manager account (MCC). |
Data ingestion from Google Ads transfers
When you transfer data from Google Ads into BigQuery, the data is loaded into BigQuery tables that are partitioned by date. The table partition that the data is loaded into corresponds to the date from the data source. If you schedule multiple transfers for the same date, BigQuery Data Transfer Service overwrites the partition for that specific date with the latest data. Multiple transfers in the same day or running backfills don't result in duplicate data, and partitions for other dates are not affected.Refresh windows
A refresh window is the number of days that a data transfer retrieves data when a data transfer occurs. For example, if the refresh window is three days and a daily transfer occurs, the BigQuery Data Transfer Service retrieves all data from your source table from the past three days. In this example, when a daily transfer occurs, the BigQuery Data Transfer Service creates a new BigQuery destination table partition with a copy of your source table data from the current day, then automatically triggers backfill runs to update the BigQuery destination table partitions with your source table data from the past two days. The automatically triggered backfill runs will either overwrite or incrementally update your BigQuery destination table, depending on whether or not incremental updates are supported in the BigQuery Data Transfer Service connector.
When you run a data transfer for the first time, the data transfer retrieves all source data available within the refresh window. For example, if the refresh window is three days and you run the data transfer for the first time, the BigQuery Data Transfer Service retrieves all source data within three days.
Refresh windows are mapped to the TransferConfig.data_refresh_window_days
API field.
To retrieve data outside the refresh window, such as historical data, or to recover data from any transfer outages or gaps, you can initiate or schedule a backfill run.
Limitations
- The maximum frequency that you can configure a Google Ads data transfer for is once every 24 hours. By default, a transfer starts at the time that you create the transfer. However, you can configure the transfer start time when you create your transfer.
- The BigQuery Data Transfer Service does not support incremental data transfers during a Google Ads transfer. When you specify a date for a data transfer, all of the data that is available for that date is transferred.
Before you begin
Before you create a Google Ads data transfer, do the following:
- Verify that you have completed all actions required to enable the BigQuery Data Transfer Service.
- Create a BigQuery Data Transfer Service dataset to store the Google Ads data.
- If you intend to set up transfer run notifications for Pub/Sub,
ensure that you have the
pubsub.topics.setIamPolicy
permission. Pub/Sub permissions are not required if you set up email notifications. For more information, see BigQuery Data Transfer Service run notifications.
Required permissions
Ensure that the person creating the data transfer has the following required permissions:
BigQuery Data Transfer Service:
bigquery.transfers.update
permissions to create the data transfer- Both
bigquery.datasets.get
andbigquery.datasets.update
permissions on the target dataset
The
bigquery.admin
predefined IAM role includesbigquery.transfers.update
,bigquery.datasets.update
andbigquery.datasets.get
permissions. For more information about IAM roles in BigQuery Data Transfer Service, see Access control reference.Google Ads: Read access to the Google Ads Customer ID or manager account (MCC) that is used in the transfer configuration.
Create Google Ads data transfer
To create a data transfer for Google Ads reporting, you need either your Google Ads customer ID or your manager account (MCC). For information about retrieving your Google Ads customer ID, see Find your Customer ID.
To create a data transfer for Google Ads reporting, select one of the following options:
Console
Go to the Data transfers page in the Google Cloud console.
Click
Create transfer.In the Source type section, for Source, choose Google Ads.
In the Transfer config name section, for Display name, enter a name for the data transfer such as
My Transfer
. The transfer name can be any value that lets you identify the transfer if you need to modify it later.In the Schedule options section:
For Repeat frequency, choose an option for how often to run the data transfer. If you select Days, provide a valid time in UTC.
- Hours
- Days
- On-demand
If applicable, select either Start now or Start at set time and provide a start date and run time.
In the Destination settings section, for Dataset, select the dataset that you created to store your data.

to prevent removed or disabled entities and metrics from being transferred. - DATA_SOURCE is the data source —
google_ads
. - TABLES is the comma-separated list of tables to include or exclude from the data transfer.
- SCHEDULE is how often you want the query to run. If
--schedule
isn't specified, the default is every 24 hours, starting from the time the transfer is created. - REFRESH_DAYS is an integer that specifies the refresh window
for a transfer configuration in days. The default value is
7
. - SERVICE_ACCOUNT_NAME is the service account name used to
authenticate your transfer. The service
account must be owned by the same
project_id
used to create the transfer and it must have all of the required permissions.
For example, the following command creates a Google Ads data transfer named
My Transfer
using Customer ID 123-123-1234
and target dataset
mydataset
. The data transfer is created in the default project:
bq mk \
--transfer_config \
--target_dataset=mydataset \
--display_name='My Transfer' \
--params='{"customer_id":"123-123-1234","exclude_removed_items":"true"}' \
--data_source=google_ads
The first time you run the command, you receive a message like the following:

Before trying this sample, follow the Java setup instructions in the BigQuery quickstart using client libraries. For more information, see the BigQuery Java API reference documentation.
To authenticate to BigQuery, set up Application Default Credentials. For more information, see Set up authentication for client libraries.
Manually trigger a Google Ads transfer
When you manually trigger a transfer for Google Ads, snapshots of Match Tables are taken once a day and stored in the partition for the latest run date. When you trigger a manual transfer, Match Table snapshots for the following tables are not updated:
- Ad
- AdGroup
- AdGroupAudience
- AdGroupBidModifier
- AdGroupAdLabel
- AdGroupCriterion
- AdGroupCriterionLabel
- AdGroupLabel
- AgeRange
- Asset
- AssetGroup
- AssetGroupAsset
- AssetGroupListingGroupFilter
- AssetGroupSignal
- Audience
- BidGoal
- Budget
- Campaign
- CampaignAudience
- CampaignCriterion
- CampaignLabel
- Customer
- Gender
- Keyword
- LocationBasedCampaignCriterion
- ParentalStatus
- Placement
- Video
PMax support
The Google Ads connector lets you export PMax campaigns data. You must select the Include PMax Campaign Tables checkbox when creating a data transfer, as PMax data is not exported by default.
Including PMax data removes
ad_group
fields from certain tables and includes new tables. You cannot include
ad_group
fields because the Google Ads API filters the PMax data.
The following tables exclude ad_group
related columns when the Include PMax
Campaign Tables checkbox is selected:
- GeoStats
- GeoConversionStats
- ShoppingProductConversionStats
- ShoppingProductStats
- LocationsUserLocationsStats
The following tables are added when the Include PMax Campaign Tables checkbox is selected:
- Asset
- AssetGroup
- AssetGroupAsset
- AssetGroupListingGroupFilter
- AssetGroupSignal
- Audience
- AssetGroupProductGroupStats
- CampaignAssetStats
Support for Google Ads manager accounts
Existing customers who have multiple Customer ID-specific Google Ads Transfers are encouraged to set up a single Google Ads Transfer at the Manager Account (MCC) level, schedule a backfill, and disable individual Customer ID-specific Google Ads Transfers.
Using Google Ads manager accounts provides several benefits over using individual Customer IDs:
- You no longer need to manage multiple data transfers to report on multiple Customer IDs.
- Cross-customer queries are much simpler to write because all the Customer IDs are stored in the same table.
- Using MCCs alleviates BigQuery Data Transfer Service load quota issues because multiple Customer IDs are loaded in the same job.
For more information about Google Ads manager accounts (MCCs), see Working with managed accounts and About linking accounts to your manager account.
Example
The following list shows the Customer IDs linked to particular Google Ads manager accounts:
- 1234567890 — root manager account
- 1234 — sub-manager account
- 1111 — Customer ID
- 2222 — Customer ID
- 3333 — Customer ID
- 4444 — Customer ID
- 567 — sub-manager account
- 5555 — Customer ID
- 6666 — Customer ID
- 7777 — Customer ID
- 89 — sub-manager account
- 8888 — Customer ID
- 9999 — Customer ID
- 0000 — Customer ID
- 1234 — sub-manager account
Each Customer ID linked to a manager account appears in each report. For more information about the Google Ads reporting structure in BigQuery Data Transfer Service, see Google Ads report transformation.

Migrate Google Ads data to MCCs
To migrate your existing Google Ads data in BigQuery Data Transfer Service to the MCC structure, you can set up a backfill to add your existing data to the tables created by the transfer configuration linked to the manager account. Note that when you schedule a backfill, match tables are not updated.
Troubleshoot Google Ads transfer setup
If you are having issues setting up your data transfer, see Google Ads transfer issues in Troubleshooting transfer configurations.
Query your data
When your data is transferred to BigQuery Data Transfer Service, the data is written to ingestion-time partitioned tables. For more information, see Introduction to partitioned tables.
If you query your tables directly instead of using the auto-generated views, you
must use the _PARTITIONTIME
pseudocolumn in your query. For more information,
see Querying partitioned tables.
Google Ads sample queries
You can use the following Google Ads sample queries to analyze your transferred data. You can also use the queries in a visualization tool such as Looker Studio. These queries are provided to help you get started on querying your Google Ads data with BigQuery Data Transfer Service. For additional questions about what you can do with these reports, contact your Google Ads technical representative.
In each of the following queries, replace dataset with your dataset name. Replace customer_id with your Google Ads Customer ID.
If you query your tables directly instead of using the auto-generated
views, you must use the _PARTITIONTIME
pseudocolumn in your query. For more
information, see Querying partitioned tables.
Campaign performance
The following sample query analyzes Google Ads campaign performance for the past 30 days.
Console
SELECT c.customer_id, c.campaign_name, c.campaign_status, SUM(cs.metrics_impressions) AS Impressions, SUM(cs.metrics_interactions) AS Interactions, (SUM(cs.metrics_cost_micros) / 1000000) AS Cost FROM `DATASET.ads_Campaign_CUSTOMER_ID` c LEFT JOIN `DATASET.ads_CampaignBasicStats_CUSTOMER_ID` cs ON (c.campaign_id = cs.campaign_id AND cs._DATA_DATE BETWEEN DATE_ADD(CURRENT_DATE(), INTERVAL -31 DAY) AND DATE_ADD(CURRENT_DATE(), INTERVAL -1 DAY)) WHERE c._DATA_DATE = c._LATEST_DATE GROUP BY 1, 2, 3 ORDER BY Impressions DESC
bq
