Effectively managing and analyzing data is key for businesses today, and BigQuery offers a solid solution for large-scale analytics.

Whether you're a Data Engineer or in Business Intelligence, understanding how to transfer data into BigQuery can improve your analytics workflow, utilizing data more effectively using SQL and therefore - the corporate culture of decision-making.

In this guide, we'll explore different ways to load data into BigQuery, covering both its built-in features and third-party tools.

By the end of this article, you'll have a clearer idea of how to make your data collection process more efficient and fully leverage BigQuery.

Whether you're working at a startup or a large enterprise, BigQuery's features ensure smooth, efficient data processing.

BigQuery handles massive datasets, making it suitable for organizations of any size. Whether you're a startup or a global company, it easily scales to meet growing data needs.

Optimized for analytics, BigQuery provides fast, reliable storage for structured, semi-structured, and unstructured data, supporting formats like JSON, Avro, and Parquet.

BigQuery integrates smoothly with visualization services like Looker Studio, Power BI or Google Sheets creating a connected data ecosystem and mankind data accessible by non-technical stakeholders.

BigQuery offers encryption and identity management, ensuring security and meeting regulatory standards like GDPR, PPDA, and HIPAA.

Google BigQuery is popular among businesses for its seamless integration with advertising services, analytics systems, CRM tools, and more.

It helps businesses automate tasks and respond quickly to market changes.

Now, let’s explore the different ways to collect data in BigQuery:

The BigQuery Data Transfer Service automates data transfers from popular sources like Google Ads, YouTube, and external platforms like Facebook Ads directly into BigQuery. This service allows users to create, configure, and monitor data transfers without manual intervention, ensuring timely and consistent updates.

The bq command-line tool manages data transfers into BigQuery, providing a more hands-on, flexible option than the web interface. It allows users to create, configure, and monitor data transfers through terminal commands, offering greater control over the data transfer process and automation options for advanced users.

Third-party paid tools offer advanced data transfer solutions for BigQuery, allowing users to connect with a wide range of platforms beyond Google’s ecosystem. These tools provide no-code options, pre-configured connectors, and support for custom schemas, making it easier to integrate and manage data from sources like Facebook Ads or CRM systems.

Custom BigQuery connectors enable smooth integration of external data sources into BigQuery, automating data ingestion without manual ETL processes.

These connectors act as direct bridges for data transfer, making analytics more efficient and reducing errors.

Businesses can tailor data workflows by building custom connectors, ensuring scalability, consistency, and accurate data flow for advanced analysis.

In this article, we’ll show you the ways of collecting data from popular sources by type of data: web analytics, ads platforms, spreadsheets, etc.

Collecting web analytics data in BigQuery is essential for in-depth insights and reporting.

For example, Google Analytics 4 (GA4) allows you to transfer event data into BigQuery automatically. Let’s take a closer look at both methods for collecting web analytics data into BigQuery.

Exporting data from Google Analytics 4 (GA4) to BigQuery allows you to analyze user behavior and site metrics more flexibly and deeply. Connecting GA4 to BigQuery will enable you to access raw event-level data for more advanced analysis.

Here’s a step-by-step guide on how to export GA4 data to BigQuery:

Step 1: Access Google Analytics Admin

Open your GA4 account and navigate to the Admin section at the page's bottom left. The Admin section manages all the property settings for your Google Analytics account.

Step 2: Select "BigQuery Linking"

Under the Property column, click on BigQuery Linking to begin setting up the connection between GA4 and BigQuery. This option lets you send raw event data directly from your GA4 property to BigQuery.

Step 3: Create a New Link

Click the Link button to create a new connection between your GA4 property and a BigQuery project. This step initiates the process of exporting data.

Step 4: Choose a BigQuery Project

Select the BigQuery project where you want to send your GA4 data. If you don't have a project, you must create one in Google Cloud Console.

Don’t forget to mark the checkbox next to the BigQuery project you want to link to your GA4 property to confirm your selection. Then click on “Confirm”.

Step 5: Select Preferred Data Location

After choosing your BigQuery project, select the preferred data location where your analytics data will be stored. It's recommended to choose a location that matches your business region to ensure compliance.

Step 6: Choose Data Streams

Next, select the data streams you want to export from GA4 to BigQuery. Depending on your needs, you can choose specific streams, such as website or app data.

Step 7: Set Up Frequency

In this step, choose the export frequency. Depending on your reporting needs, you can select between daily exports for regular data updates streaming exports for near real-time data analysis.

Step 8: Submit

After configuring all settings, click Submit to finalize the setup. This will initiate the linking process between GA4 and BigQuery.

Step 9: Linking Complete

Once submitted, the connection between your GA4 property and BigQuery is established, and data will start transferring based on the schedule you’ve set.

Transferring Google Ads data to BigQuery allows merging campaign performance data with GA4 event data, enabling an overview of customer behavior and ROI.

Steps to Set Up Google Ads Data Transfer to BigQuery:

Step 1: Create a Dataset in BigQuery

• Open the BigQuery Console and click on the three dots next to your project name.
• Select Create dataset, name it, and configure the settings. Ensure the dataset is in the same region as your GA4 event data.

Step 2: Configure Data Transfer

• Go to Google Cloud Console and navigate to BigQuery > Data Transfers.

• Click Create Transfer and enable the Data Transfer API if necessary.

• Select Google Ads as the source, configure the display name, schedule frequency, dataset, and Google Ads customer ID. Optionally, include Performance Max campaign data. Click Save.

• Now, configure the transfer settings- choose any display name, set the schedule (hours, days, weeks, or months), select your new dataset, and enter your Google Ads customer or MMC ID. If running Performance Max campaigns, select "Include PMax Campaign Tables”. The refresh window is 7 days by default, extendable to 30. Enable email notifications if needed, then click Save.

Step 3: Backfill Data Transfer

• The transfer will be scheduled for the next day. To run the transfer manually, click Schedule backfill.

• Choose a date range or run a one-time transfer. Backfilling large datasets may take time.

Step 4: First Query

Run your first query by replacing in the sample query provided to analyze metrics like impressions, interactions, and cost for your Google Ads campaigns.

This query retrieves Google Ads campaign performance data from the last 31 days. It calculates total impressions, interactions, and cost for each campaign, joining campaign details with basic campaign statistics

Transferring Facebook Ads data to BigQuery allows businesses to merge ad performance metrics with other datasets.

There are three key methods for this transfer: manual data uploads, using API-based connections, or opting for no-code automated tools for seamless, ongoing transfers.
