| 21 | |
| 22 | 1. **Test one variable at a time** — Change only the element being tested |
| 23 | 2. **50/50 split** — Equal traffic to each variant |
| 24 | 3. **Minimum sample size** — At least 100 conversions per variant before calling a winner |
| 25 | 4. **Statistical significance** — Wait for 95% confidence before declaring a winner |
| 26 | 5. **Run for at least 7 days** — Captures day-of-week variations |
| 27 | 6. **Document everything** — Record hypothesis, variant details, and results |
