Data Collection Methodologies

Performance Metrics Collection

Performance data was collected using the following methods:

  1. Synthetic Testing:
    • Tool: Lighthouse audits
    • Sample Size: 245 pages across 158 stores
    • Metrics: LCP, FID, CLS, TTI, TBT, FCP
    • Frequency: 3 tests per page, averaged
    • Connection: Simulated 4G
    • Devices: Mobile and desktop profiles
  2. Real User Monitoring:
    • Tool: Google CrUX data
    • Sample Size: 1,200+ Shopify stores
    • Time Period: 28-day rolling window
    • Segmentation: By device, connection type, geographic region
  3. A/B Testing:
    • Methodology: Split traffic between Liquid and Hydrogen for 17 stores
    • Duration: 4-8 weeks per test
    • Traffic Volume: Minimum 100,000 sessions per variant
    • Controlled Variables: Same products, pricing, campaigns

Economic Analysis Methodology

Business impact projections were developed using:

  1. Performance-Revenue Correlation Model:
    • Base Data: 3 years of performance/revenue data from 86 stores
    • Variables: 12 performance metrics, 8 business outcomes
    • Statistical Method: Multiple regression analysis
    • Validation: Back-testing against known outcomes
    • R² Value: 0.78 (strong correlation)
  2. TCO Calculation Method:
    • Components: Implementation, maintenance, feature development, infrastructure, optimization
    • Time Horizon: 3-year analysis
    • Discount Rate: 7% for future value calculation
    • Sensitivity Analysis: ±20% on all inputs
  3. ROI Modeling:
    • Formula: (Gained Revenue + Cost Savings - Implementation Costs) / Implementation Costs
    • Revenue Attribution Method: Incremental analysis with control group comparison
    • Confidence Interval: 80-90% depending on merchant segment

Sample Size and Statistical Significance

Data Category Sample Size Population Confidence Level Margin of Error Statistical Significance
Performance Metrics 158 stores ~2M Shopify stores 95% ±7.8% p < 0.01
Agency Rates 312 agencies ~10K agencies 95% ±5.5% p < 0.01
Conversion Impact 47 stores with before/after data ~29K Plus stores 90% ±12% p < 0.05
Development Efficiency 28 development teams ~5K Plus partner teams 85% ±15% p < 0.05
Customer Experience 835 end users Shopify customer base 95% ±3.4% p < 0.01

Data Limitations and Adjustments

  1. Selection Bias Mitigation:
    • Early Hydrogen adopters may represent more technically advanced merchants
    • Adjustment: Comparative analysis limited to merchants of similar technical sophistication
    • Weighting: Results weighted by merchant segment to reflect broader ecosystem
  2. Performance Attribution:
    • Multiple factors can influence conversion beyond technology
    • Adjustment: Isolated technology impact using control periods and A/B testing
    • Validation: Confirmed patterns across multiple implementations
  3. Cost Projection Limitations:
    • Agency rates vary significantly by geography and expertise
    • Adjustment: Regionalized cost data with range presentations
    • Validation: Cross-referenced with actual project quotes
  4. Forecast Confidence Decreasing Over Time:
    • Projections beyond 24 months have increased uncertainty
    • Adjustment: Wider ranges for long-term projections
    • Validation: Multiple scenario modeling with probability weighting
