      Uncover the Benefits, Challenges, and Step-by-Step Setup for GA4 Integration

      IN THIS ARTICLE YOU WILL:

      Overview

      Using Google Analytics 4 (GA4) to measure Convert.com split tests offers powerful analytics capabilities, but it also comes with certain trade-offs. GA4 provides advanced segmentation, user-centric metrics, and seamless integration with Google services, making it a valuable tool for analyzing your experiments. However, its complexity and the need for manual setup of test reporting can introduce challenges. Let's explore the benefits and drawbacks before diving into a step-by-step guide to streamline your integration and maximize the insights from your A/B tests.

      Benefits:

      • Advanced Analytics: GA4 provides robust analytics capabilities, including user-centric measurement, cross-device tracking, and advanced segmentation.
      • Flexible Reporting: Create custom reports and explorations tailored to your specific needs.
      • Integration: GA4 natively integrates with other Google products, such as Google Ads and BigQuery.
      • Scalability: GA4 can handle large volumes of data, making it suitable for enterprise-level testing.
      • Using Google Analytics, enables marketers to analyze test data more fluently using advanced segmentation, allowing them to integrate the data with media spend, SEO, and other analytics.
      • Cost savings related to Google Analytics 4 being a free tool

      Drawbacks:

      • Complexity: GA4 has a steeper learning curve compared to other analytics tools.
      • No Out-of-the-Box Test Reporting: Unlike Convert's native reporting, GA4 requires manual setup for test analysis.
      • Data Discrepancies: Minor differences in tracking methods may lead to slight discrepancies between Convert and GA4 data.
      • Limited Historical Data: GA4 does not support retroactive data collection, so test data is only available from the time of integration.
      • Having the evaluation on a different tool than the testing tool, increases the chances of errors, latency, and complexity.

      Now that we've considered the pros and cons let's dive into the setup process.

      Step 1: Initial Setup

      Prerequisites:

      • Convert.com account with tracking code
      • GA4 property and tracking code
      • Both codes properly placed (Convert before GA4)

      Step 2: Enable Convert-GA4 Integration

      Project Level Integration:

      • Navigate to Project Configuration > Integrations
      • Select "Google Analytics" and "Google Analytics 4 Integration"
      • Authenticate with Google
      • Select your GA4 property and data stream
      • Alternative: Experience Level Integration
      • Set up GA4 integration per individual experience

      Step 3: Create GA4 Audiences

      After activating your experience:

      • Use Convert's "Create GA4 Audiences" feature
      • Verify audience creation in GA4
      • Note: Keep experience names under 255 characters

      Step 4: Analyze Results in GA4

      Two methods to analyze data:


      Method 1: Using GA4 Audiences

      • Reports > Acquisition > Traffic Acquisition
      • Add comparison using Audience name
      • Select variation audiences
      • Add relevant metrics

      Method 2: Using Experience Impression Event

      • Create custom dimension for experience_impression:
        • Use format: CONV-[Experience ID]-[Variation ID]
      • Create exploration report:
        • Example Data Analysis:

        • Let's say you're testing a new checkout page:

          Variation Users Conversions Conv. Rate
          Control 10,000 500 5.00%
          Variation 1 10,000 600 6.00%

      Step 5: Statistical Analysis


      Use an A/B test calculator (like abtestguide.com/calc/):

      Input:

      • Control: 10,000 visitors, 500 conversions (5.00%)
      • Variant: 10,000 visitors, 600 conversions (6.00%)
      • Confidence Level: 95%
      • Two-tailed test

      The calculator would show:

      • Statistical significance achieved
      • Relative improvement: 20%
      • P-value: 0.003
      • Confidence interval: 0.5% to 1.5%

      Important Metrics to Track in GA4:

      • Conversion events
      • Engagement metrics
      • User behavior flows
      • Custom events
      • Session duration

      Pro Tips:

      Data Quality:

      • Use GA4 DebugView for verification
      • Monitor audience creation
      • Check real-time reports initially
      • Best Practices:
      • Wait for statistical significance
      • Use consistent naming
      • Document test configurations
      • Consider seasonal effects

      Advanced Analysis:

      • Create custom explorations
      • Use path analysis
      • Compare segments
      • Analyze user behavior patterns

      Troubleshooting:


      If data isn't appearing:

      • Check tracking code placement
      • Verify GA4 property settings
      • Confirm audience creation
      • Review browser cookie settings

      Remember:

      • Always wait for statistical significance
      • Consider sample size requirements
      • Document all test configurations
      • Monitor data quality regularly
      • This method provides clean, reliable data analysis while leveraging GA4's powerful segmentation and reporting capabilities. However, it also comes with certain trade-offs, such as increased complexity and potential data discrepancies. Need help? Convert's support team is available 24/7.
