Methods to connect Google Analytics to Looker

There are multiple ways in which you can connect Google Analytics to Looker:

Method 1: Using BigQuery transfer service

Google Analytics supports loading data to Looker via Bigquery for further analysis. Google Analytics 360 and BigQuery, are both Google products and hence, Google provides a data migration solution to transfer your data from one product to another. This is known as the BigQuery Data Transfer Service. In this method, you will first load your Google Analytics data into the BigQuery data warehouse and then connect it to Looker.

But this comes with a caveat. It is only available for premium users who can afford to pay thousands of dollars per year. In case you are a GA360, premium users, you can use the following steps to connect Google Analytics to Looker:

Step 1: Connecting Google Analytics to BigQuery

Use BigQuery Data Transfer service to move your data from Google Analytics to BigQuery. You can check out our easy step-by-step guide to help you load your Google Analytics data. You can schedule the data transfer to occur for a defined frequency as per your business’s data needs.

Step 2: Loading data from BigQuery to Looker

Once you’ve successfully transferred your Google Analytics data into BigQuery, you can now connect BigQuery to Looker to start analyzing your data. Check out our detailed and easy guide to help you connect BigQuery to Looker using Lookers’ connection settings.   

Limitations of this method

  • This method requires you to have the Google Analytics 360 privileged access, which comes at a very hefty price. Most small business would find this method economically difficult for them to implement.
  • There is very less scope of customization in the BigQuery Data Transfer service.

Method 2: Using PostgreSQL as an intermediate database

You can use Google Analytics Reporting APIs to fetch data and then store it in PostgreSQL. Now connect your PostgreSQL database to Looker to start analyzing your data. You can implement this using the following steps:

Step 1: Connecting Google Analytics to PostgreSQL

Google Analytics makes its data available through the Google Reporting API V4. The API can be accessed by authenticating the OAuth protocol. You can check our detailed guide, to help you load data into PostgreSQL.

Step 2: Loading data from PostgreSQL to Looker

Once you have transferred data into PostgreSQL, log in to your PostgreSQL shell and create a user for Looker and provide the necessary permissions. You can do this using the following lines of code:

CREATE USER looker WITH ENCRYPTED PASSWORD 'some_password_here';
GRANT CONNECT ON DATABASE database_name to looker;

Launch Looker and login to your dashboard. Click on the Connections tab and select the new connection option.

This is how you can connect Google Analytics to Looker by using PostgreSQL as an intermediate database.

Limitations of this method

  • To always have up-to-date data in Looker, you need to refresh the data periodically. This requires users to write custom code lines that can periodically perform a data refresh. This can be a challenging task for the users.
  • This method requires users to make multiple configurations to access APIs repeatedly.
