In the world of digital marketing, understanding customer purchase behavior is the cornerstone of driving sales and improving ROI. The synergy between Looker Studio, a versatile data visualization tool from Google, and Google Analytics 4 (GA4) empowers marketers to gain actionable insights into key metrics like average order value (AOV) and conversion rates. These metrics, when analyzed effectively, provide a window into the health of e-commerce strategies and the performance of individual marketing channels.
One of the most valuable dashboards that marketers can create in Looker Studio leverages GA4 data to analyze purchase behavior segmented by Session Default Channel Group. This grouping offers a breakdown of performance across key traffic sources, such as Direct, Organic Search, Referral, Paid Search, Email, and more. By understanding how these channels contribute to conversions and average order value, marketers can identify areas of strength and opportunities for improvement.
In this blog post, we’ll explore how to use Looker Studio and GA4 to monitor and optimize purchase behavior. We’ll also discuss how these tools can be harnessed to make data-driven decisions that improve marketing effectiveness.
Average Order Value Conversion
Understanding Average Order Value and Conversion Rates
What Is Average Order Value?
Average Order Value (AOV) measures the average dollar amount spent per order on your website. It’s calculated by dividing total revenue by the number of orders.
Formula:

A high AOV indicates that customers are purchasing more expensive items or multiple products per order, making it an essential metric for e-commerce success.
What Are Conversion Rates?
A conversion rate represents the percentage of visitors who take a desired action on your website, such as making a purchase. For e-commerce, this metric measures how effectively you’re turning visitors into paying customers.
Formula:

While AOV focuses on the value of transactions, conversion rates highlight how well your site drives those transactions. Together, these metrics form a comprehensive view of purchase behavior.
How Looker Studio and Google Analytics 4 Work Together
Looker Studio (formerly Google Data Studio) is a robust platform that allows users to create customized dashboards by connecting to various data sources, including Google Analytics 4. With GA4, marketers gain access to event-based tracking, giving them deeper insights into user behavior across the entire customer journey.
When Looker Studio connects to GA4, the combination enables marketers to visualize and analyze purchase behavior in meaningful ways, such as segmenting data by Session Default Channel Group to assess performance by channel.
Building the Ultimate Purchase Behavior Dashboard in Looker Studio
Why Focus on Session Default Channel Group?
The Session Default Channel Group categorizes website traffic into predefined groups such as Organic Search, Direct, Referral, Paid Search, Email, and others. This segmentation provides an at-a-glance view of where your website traffic is coming from and how these channels contribute to conversions and average order value.
Analyzing purchase behavior by channel group is crucial because:
Identifying Strengths: Some channels, such as Email or Organic Search, may consistently drive high conversions or AOV.
Spotting Weaknesses: Other channels, like Paid Search or Referral, might underperform, signaling a need for optimization.
Resource Allocation: By understanding channel performance, marketers can allocate budgets more effectively.
Dashboard Essentials
A well-designed Looker Studio dashboard for purchase behavior should include the following metrics:
Users by Channel Group: Understand which channels bring the most traffic.
E-commerce Purchases by Channel Group: Identify how many purchases each channel drives.
Conversion Rates by Channel Group: Measure how well each channel converts visitors into customers.
Average Order Value by Channel Group: Assess the revenue impact of each channel.
This dashboard provides a comprehensive overview of traffic, conversions, and revenue performance for each channel, helping marketers pinpoint which areas need attention.
Steps to Create the Dashboard
1. Connect Looker Studio to GA4
Begin by linking Looker Studio to your GA4 account. GA4’s native integration ensures seamless data import.
2. Build a Data Source
Set up your data source by selecting relevant metrics and dimensions. For this dashboard, include:
Session Default Channel Group
Users
E-commerce Purchases
Conversion Rate
Average Order Value
3. Design the Dashboard Layout
Organize your dashboard for clarity:
Use bar charts or tables to display users, purchases, and AOV by channel.
Add trend lines to monitor conversion rate performance over time.
4. Segment by Session Default Channel Group
Apply filters or groupings in Looker Studio to visualize metrics for each channel group. This segmentation enables easy comparison between channels.
5. Incorporate Interactivity
Enhance the dashboard with interactive features, such as:
Date range selectors to analyze specific periods.
Drill-down capabilities to explore detailed data for each channel.
Testing and Optimizing Marketing Channels
Once your dashboard is live, it becomes a powerful tool for identifying channel strengths and weaknesses. Here’s how to leverage it for optimization:
1. Test Channels with Low AOV or Conversion Rates
If a channel like Paid Search has a low average order value, experiment with campaigns targeting higher-priced products. Similarly, improve conversion rates by optimizing ad copy, landing pages, or offers.
2. Double Down on High-Performing Channels
Channels with high AOV or strong conversion rates, such as Email, should receive more resources. Consider scaling these efforts through additional campaigns or promotions.
3. Evaluate Trends Over Time
Use your dashboard’s trend analysis to monitor the impact of changes. For instance, if adjusting email frequency improves AOV, replicate this strategy across other channels.
