Analytics Integrations with Stellar

Last Updated: 2024-03-07

Stellar can integrate with your existing analytics tools to provide a more comprehensive view of your experiment performance. This guide explains how our analytics integrations work and how to set them up.

Google Analytics 4 (GA4) Integration

Overview

When you enable GA4 integration in Stellar, we automatically send experiment and conversion events to your Google Analytics 4 property. This allows you to:

• View experiment data alongside your other analytics
• Create custom reports and segments based on experiment participation
• Analyze experiment impact on your key metrics
• Track conversions in both Stellar and GA4 simultaneously

Requirements

To use the GA4 integration, you must:

• Have Google Analytics 4 properly installed on your website
• Have the gtag function available in the global scope
• Enable GA4 integration at the project level in Stellar

Events Sent to GA4

Stellar sends the following events to GA4:

1. Experiment View Event

When a user views an experiment variant, Stellar sends a stellar_experiment_view event with the following parameters:

{
  "event": "stellar_experiment_view",
  "experiment_id": 12345,
  "experiment_name": "Homepage Hero Test",
  "variant_id": 6789,
  "variant_name": "Variant A"
}

2. Conversion Event

When a user triggers a conversion that has GA4 integration enabled, Stellar sends a stellar_experiment_conversion event with the following parameters:

{
  "event": "stellar_experiment_conversion",
  "experiment_id": 12345,
  "experiment_name": "Homepage Hero Test",
  "variant_id": 6789,
  "variant_name": "Variant A",
  "conversion_id": 101112,
  "conversion_name": "Add to Cart"
}

Setting Up GA4 Integration

Step 1: Enable GA4 Integration at the Project Level

1. Go to your Projects page in Stellar
2. Click "View Integrations" on the project you want to integrate
3. Toggle on the Google Analytics 4 (GA4) integration

Analyzing Experiment Data in GA4

Once integration is set up, you can:

• Create custom reports in GA4 using the experiment_view and experiment_conversion events
• Create segments based on experiment participation
• Analyze how experiment variants affect other metrics like bounce rate, session duration, etc.
• Use GA4's exploration reports to dive deeper into experiment performance

Troubleshooting

If you're not seeing experiment data in GA4:

• Verify that GA4 is properly installed on your site
• Check that the gtag function is available in the global scope
• Ensure that GA4 integration is enabled at both the project and conversion level (if applicable)
• Look for any JavaScript errors in your browser console
• Allow up to 24 hours for data to appear in GA4 reports
