Split Testing
Split testing is a structured experimentation framework encompassing both A/B testing and multi-variate testing approaches. A/B testing isolates single variables to measure their specific impact, while multi-variate testing examines how multiple elements interact to affect performance. Both methods require statistical rigor, proper audience sampling, and sufficient traffic volume to produce reliable insights for creative optimization.

Examples
A/B test: Testing a single headline variant against control with all other elements identical
Multi-variate test: Examining interactions between headline, image, and CTA variations
Sequential split test: Testing winning variants against new challengers
Audience segment split test: Comparing creative performance across different user groups
Best Practices
- ✓Ensure statistical significance before drawing conclusions
- ✓Control for external variables that could skew results
- ✓Test one variable at a time in A/B tests
- ✓Account for audience segment differences in analysis
