Growth experiments vs optimization vs A/B testing: Stop confusing them

Growth experimentation and optimization is not the same thing. Many people get this wrong and confuse the two. Throw in A/B testing and people start running around like headless chicken. This isn’t just semantic nitpicking – using the wrong approach at the wrong time leads to invalid data, wasted effort, and missed growth opportunities.
This guide will clarify the critical differences between growth experiments, optimizations, and A/B tests – showing you exactly when and how to use each approach for maximum impact.
