Hypothesis
IF we expose the size filter on the PLP THEN the ARPU increases Because users can only see available products in their size which makes the shopping experience more individual and the frustration and FOMO caused by non-existent sizes is reduced.
Outcomes and Implications
| Psychological Mechanism | Personalization / Friction Reduction / FOMO |
|---|---|
| Predicted Winrate | 50% 🔼 |
| Strategic Implication | Make the size filter visible by default to create a smoother, more individualized shopping experience. |
