Why Repeating the Same A/B Test Multiple Times Is Wrong and How to Conduct Reliable Experiments

Repeating the same A/B test inflates false‑positive rates, creates inconsistent results, and hampers decision‑making, so a single well‑designed experiment with proper metrics, traffic allocation, analysis, and decision steps is essential for reliable product evaluation.
