Short-Term Wins, Long-Term Carnage
Optimizing A/B lifts without measuring downstream effects builds experience debt.
Chasing A/B test lifts, conversions, and clicks without measuring downstream effects, long-term satisfaction, retention, and trust erosion accumulates experience debt. The customer journey does not end at checkout, so neither should the measurement.
A/B lifts, conversion bumps, and click gains are seductive because they arrive fast. But when nobody measures downstream effects, long-term satisfaction, retention, or trust erosion, those wins can quietly compound into experience debt.
Experience debt works like technical debt: each short-term optimization that degrades the broader experience is a loan against future retention. The interest shows up later, in churn and eroded trust, disconnected from the test that caused it.
The customer journey does not end at checkout.

Reading about short-term wins, long-term carnage is one thing. Seeing where it applies in your journey is the useful part.
