Why your āwinningā A/B tests from 2024 are likely losing you money in 2026
Timeless lessons in this academy. Victor really touched on a reality that most CRO āgurusā on X and LinkedIn conveniently avoid. Weāve all seen the posts: āWe added X and unlocked $300k in yearly profit!ā The implication is simple: rollout the winner, keep it that way, and collect the gains forever. In reality, it doesnāt work like that. Thereās a brand Iāve been working with for almost two years now. We had clear wins in early 2024. But as the brand scaled and ad spend more than tripled, something important changed: the customer cohort evolved. The people buying today arenāt the same people who were buying 18 months ago. Following Victorās advice, I went back and re-tested some of those āall-time winners.ā The result? Some segments improved, but others completely tanked. The data had flipped. Thatās the part most people donāt talk about. Testing isnāt ādo it once and forget it.ā Itās a continuous cycle: test ā roll out ā monitor ā re-test ā adapt. The brands that keep winning arenāt the ones chasing permanent wins.Theyāre the ones who accept that markets move, customers change, and experimentation has to evolve with them. That mindset alone makes this academy worth going through.
