A/B Testing
Basics of A/B testing: setup, metrics, and common pitfalls.
A/B testing is the process of comparing two versions (A and B) to see which performs better under controlled conditions.
Setup steps
- Define the goal metric (e.g. click rate)
- Split traffic randomly
- Run until statistical significance
- Analyze results (use confidence intervals)
Avoid bias, ensure sample size is enough, and test one variable at a time.
