Problem: A new checkout variation wins on conversion rate, but stakeholders worry it may introduce hidden UX issues or long-term friction that aren’t visible in topline metrics alone. Solution: Convert flags the winning variation while Smartlook, enriched with experiment and variation events, lets teams filter replays and heatmaps to only those users. They visually inspect journeys to confirm there’s no new friction. Outcome: Teams ship winners with confidence, backed by both quantitative uplift and qualitative evidence. This reduces rollback risk, accelerates deployment, and builds trust in experimentation decisions.
