Segmenting Conversions in Google Analytics 4 with (our) Custom Dimensions: A Step-by-Step Guide

Google Analytics 4 (GA4) allows you to segment conversions and analyze user behavior using custom dimensions. This guide will demonstrate how to create, configure, and apply custom dimensions to segment conversions using GA4. The examples used in this guide will focus on AB Split Test custom event-based dimensions: test_event, test_name, and test_variation.

Step 1: Define Your Custom Dimension

Make sure you have configured your ab split test dimensions by following these instructions

Step 2: Applying Custom Dimensions to Reports

With custom dimensions created, you can apply them to segment conversions in GA4 reports.

Segmentation in Standard Reports

• Go to the “Reports” section in GA4.
• Choose a relevant report where you’d like to apply your custom dimension.
• At the top of the report, click “Add comparison.”
• Select your custom dimension (e.g., test_event, test_name, or test_variation) to compare different segments within the report.

Using Custom Dimensions in Exploration Reports

• Click “Explore” in the GA4 sidebar to create an Exploration report.
• Choose a template or start from a blank exploration.
• Add your custom dimension to the “Dimensions” section using the “+” icon.
• Drag and drop the custom dimension into the “Rows” or “Columns” section, depending on your desired report structure.
• Add appropriate metrics, such as “Conversions,” to track outcomes based on the custom dimension.
• Customize the report further by adding filters or additional breakdowns.
