Google Ads is one of the modern marketer’s favorite channels to grow the business. If you are someone who has even glanced at the Google Ads interface would know that Google provides a gazillion data points to optimize and run personalized ads. The huge amount of diverse data points available makes performance tracking a complex and time-consuming task.

Well, the complexity increases further when Businesses want to build a 360-degree understanding of how Google Ads fare in comparison to other marketing initiatives (Facebook Ads, LinkedIn Ads, etc.). To enable a detailed, convoluted analysis like this, it becomes important to extract and load the data from all the different marketing platforms used by a company to a robust cloud-based Data Warehouse like Google BigQuery. This blog talks about the different approaches to use when loading data from Google Ads to BigQuery

Changing API endpoints and limits, ad-hoc data preparation, and inconsistent schema makes maintaining such a system nightmare. Hevo’s reliable no-code data pipeline platform enables you to set up zero-maintenance data pipelines that just work.

Wide Range of Connectors – Instantly connect and read data from 150+ sources including SaaS apps and databases, and precisely control pipeline schedules down to the minute.

Method 2: Using BigQuery Data Transfer Service to Connect Google Ads to BigQuery

Before you begin this process, you would need to create a Google Cloud project in the console and enable BigQuery’s API. Also, you need to enable billing on your Google Cloud project. This is a mandatory step that needs to be executed once per project. In case you already have set up a project, you would only need to enable the BigQuery API. 

  1. On the BigQuery platform, hit the “Create a Dataset” button and fill out the Dataset ID and Location fields. This will create a dedicated space for storing your  Google Ads data.
  2. Next, enable BigQuery Data Transfer Service from the web UI. Note – you would need to have admin access to transfer and update the data. 
  3. Click on the “Add Transfer” button. Select “Google Ads” in the source and destination dataset. 
  4. BigQuery’s data connector allows you to set up refresh windows (the max offered is 30 days) and a schedule to export the Google Ads data.
  5. Now, enter your Google Ads Customer ID or Manager Account (MCC).
  6. Next, allow the ‘Read’ access to the Google Ads Customer ID. This is needed for the transfer configuration.
  7. It is generally a good practice to opt for email notification in case a loading failure occurs.

Despite this being a native integration with two products available from Google, there are a few limitations that make companies look out for other options. 

Limitations of using BigQuery Data Transfer Service to Connect Google Ads to BigQuery

  • BigQuery Data Transfer Service supports a maximum of 180 days per data backfill request. This means you would have to manually transfer any historical data.
  • Since the business teams that need this data are not very tech-savvy, using this approach would necessarily mean that a company would need to invest tech bandwidth to move data. This is an expensive affair. 
  • While transferring data, you need to remember that BigQuery doesn’t allow joining datasets saved in different location servers later. So, always create datasets in the same locations across your project. Hence, you need to be careful initially while setting up as there’s no option to change the location later. 
  • Say you want to convert the timestamp in the data from UTC to PST, such modifications are not supported on the BigQuery Transfer service. 
  • BigQuery transfer service can only bring data from Google products into BigQuery. In the future, in case you want to bring data from other sources such as Salesforce, Mailchimp, Intercom, and more, you would need to use another service.
