How to Connect Multiple Data Sources in Looker Studio (Step-by-Step Overview)
Want to build a dashboard that pulls data from GA4, YouTube, Facebook, LinkedIn, and more, all in one place?
In this tutorial, we walk through how to connect and blend multiple data sources in Looker Studio to create powerful, unified reports.
Here’s what you’ll learn:
>> Add Multiple Data Sources to One Report
You can connect different platforms (such as GA4 and YouTube) and display their metrics side by side in a single dashboard.
For example:
Website Users (GA4)
YouTube Views
Social Media Metrics
Perfect for social dashboards or multi-channel performance snapshots.
>> Blend Data into a Single Chart
Need to combine data from two GA4 properties into one roll-up report? That’s where blended data comes in.
To blend data, you’ll:
> Choose a common key (like Date)
> Select dimensions and metrics from each source
> Configure the join type (Left, Right, Inner, Full Outer, Cross)
> Create calculated fields (e.g., Total Users Combined = Property A + Property B)
This lets you combine metrics like:
Total Users
Sessions
Conversions
All into one unified visualization.
Pro Tip:
Name your tables clearly when blending data. It makes creating calculated fields much easier, especially in complex reports.
You can even quickly blend two scorecards by selecting them → right-click → Blend Data. It’s the fastest way to combine metrics from multiple sources.
Connecting multiple data sources in Looker Studio isn’t just useful; it’s essential for:
Cross-channel reporting
Executive dashboards
E-commerce roll-ups
Multi-platform marketing analysis
