Google Merchant Center Transfers
The BigQuery Data Transfer Service for Google Merchant Center lets you automatically schedule and manage recurring load jobs for Google Merchant Center reporting data.
Supported reports
The BigQuery Data Transfer Service for Google Merchant Center supports the following data:
Products and product issues
The products and product issues report includes product data provided to Merchant Center through feeds or using the Content API for Shopping. This report also includes item level issues detected by Google for your products. You can view product and product issues data in the Google Merchant Center or by querying the Content API for Shopping. For information on how this data is loaded into BigQuery, see the Google Merchant Center product table schema.
Regional Inventories
The regional inventories report includes additional product data about regional availability and pricing overrides of your products.For information on how this data is loaded into BigQuery, see the Google Merchant Center regional inventories table schema.
Local Inventories
The local inventories report includes additional product data about local inventory of your products. This report contains data on local pricing, availability, quantity, pick-up and in-store product location. For information on how this data is loaded into BigQuery, see the Google Merchant Center local inventories table schema.
Performance
The performance report provides granular segmentation of your performance data across both Ads and Free Listings. For information on how this data is loaded into BigQuery, see the Google Merchant Center performance table schema.
Best Sellers
The Best sellers report provides the same data found in the Google Merchant Center UI and lets you backfill the data across countries or categories for up to 2 years. This includes data about the most popular products and brands in Shopping ads and unpaid listings, as well as whether or not you have them in your inventory. This report is based on the best sellers report available through Google Merchant Center. For information on how this data is loaded into BigQuery, see the Google Merchant Center best sellers tables schemas.
Price Competitiveness
Formerly known as the price benchmarks report, the price competitiveness report includes product level attributes and price benchmark data and is based on the same definitions as the price competitiveness report available through Google Merchant Center. For information on how this data is loaded into BigQuery, see the Google Merchant Center price competitiveness table schema.
Price Insights
Use the price insights report to see suggested sale prices for your products, and predictions for the performance that you can expect if you update your products' prices. Using the price insights report can help you price your products more effectively. For more information on how to use the data in this report, see Improve product pricing with the price insights report for more information on how to use the data in this report. For information on how this data is loaded into BigQuery, see the Google Merchant Center Price Insights table schema.
Product Targeting
Enable the Product Targeting report when you set up a transfer to expose Ads targeting information when you load data from Google Shopping into BigQuery. For information on how the data is loaded into BigQuery, see the Google Merchant Center Product Targeting table schema.
Reporting options
The BigQuery Data Transfer Service for Google Merchant Center supports the following reporting options:
Reporting option | Support |
---|---|
Schedule | Configurable to daily, weekly, monthly, or custom. By default, this is set to daily when the transfer is created. The minimum interval between transfers is 6 hours. |
Data ingestion from Google Merchant Center transfers
When you transfer data from Google Merchant Center 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.Limitations
Some reports might have their own constraints, such as different windows of support for historical backfills. The following sections describe the limitations for each report.
Historical Backfills Support
Not all reports support historical backfills in the same way. The following are a list of reports and the level of support for historical backfills.
- Products and product issues - 14 days
- Local Inventories - 14 days
- Regional Inventories - 14 days
- Performance - 2 years
- Best sellers - 2 years
- Price competitiveness - No backfill support
- Price insights - No backfill support
Automatic Backfill Transfer Runs
The Performance report can have latencies in "today's" data. Therefore, when a data export is requested, data might update up to 3 days in the past to account for corrections.
To support this functionality, whenever a transfer is triggered on any report,
two more transfer runs are created for today - 1
and today - 2
. These
transfer runs only affect the Performance table; other tables are not impacted.
The automatic backfills can't be disabled.
Product and product issues
- Products and product issues data in BigQuery does not represent the
real-time view of your Merchant account. To see the timeline of your
data, refer to the
product_data_timestamp
field in the schema.
Price benchmarks
- Price benchmarks data does not represent the real-time view of price
benchmarks. To see the timeline of your data, refer to the
price_benchmark_timestamp
field in the Price Benchmarks schema. - Not all products will have a price benchmark.
Best sellers
- Not all countries will contain ranking data. Countries included in the report (using ISO 3166-1 alpha-2): AT, AU, BE, BR, CA, CH, CZ, DE, DK, ES, FI, FR, GB, HU, IE, IN, IT, JP, MX, NL, NO, NZ, PL, PT, RO, RU, SE, SK, TR, UA and US.
- Best sellers data does not represent a real-time view of brand rankings.
To see the timeline of your data, refer to the
rank_timestamp
field in theBestSellers_TopProducts_
andBestSellers_TopBrands_
schema. - There may be rows in the
Products_
table with agoogle_brand_id
that does not map to any brands in theBestSellers_TopBrands_
table. - Brand IDs in the
google_brand_id
field might change over time to reflect the changing nature of businesses and brands. Because of this, tracking a set of brands over a long period of time is not guaranteed. - While brands are ranked across many different categories, all products in the
Products_
table are in leaf categories. To join brands and products on non-leaf categories, use thegoogle_product_category_ids
field, as shown in Best sellers sample queries.
Multi-client account (MCA) support
Existing customers with multiple Merchant IDs are encouraged to configure a parent Multi-Client Account (MCA). Configuring an MCA lets you create a single transfer for all your Merchant IDs.
Using Google Merchant Center MCAs provides several benefits over using individual Merchant IDs:
- You no longer need to manage multiple transfers to transfer reporting data for multiple Merchant IDs.
- Queries involving multiple Merchant IDs are much simpler to write because all Merchant ID data is stored in the same table.
- Using MCAs alleviates potential BigQuery load job quota issues because all your Merchant ID data is loaded in the same job.
One possible disadvantage of using MCAs is that your subsequent query costs are likely to be higher. Because all of your data is stored in the same table, queries that retrieve data for an individual Merchant ID must still scan the entire table.
If you are using an MCA, the MCA ID is listed under aggregator_id
and the
individual sub-accounts are listed under merchant_id
. For accounts that
don't use an MCA, aggregator_id
is set to null
.
Not all reports support MCAs. MCAs are supported by the following reports:
- Products and product issues
- Local Inventories
- Regional Inventories
- Product Performance
- Price Competitiveness
- Price Insights
- Product Targeting
Query your data
When your data is transferred to BigQuery, the data is written to ingestion-time partitioned tables. For more information, see Introduction to partitioned tables.
When you query your Google Merchant Center table, you
must use the _PARTITIONTIME
or _PARTITIONDATE
pseudocolumn in your query.
For more information, see Querying partitioned tables.
The Products_
table contains nested and repeated fields. For information on
handling nested and repeated data, see
Differences in repeated field handling
in the GoogleSQL documentation.
Google Merchant Center sample queries
You can use the following Google Merchant Center sample queries to analyze your transferred data. You can also use the queries in a visualization tool such as Looker Studio.
In each of the following queries, replace dataset with your dataset name. Replace merchant_id with your Merchant ID. If you're using an MCA, replace merchant_id with your MCA ID.
