Summary

Second in the Three Pillars framework. Where Findability asks “Can users find what they’re looking for?”, Discovery asks “Can users find things they didn’t know they were looking for?”

Key Distinguishing Insight

Discovery acknowledges the emotionally important discovery phase — brand storytelling, visual merchandising, curated product experiences that inspire purchases through narrative and variety. Pure retrieval metrics miss this entirely.

Core Techniques

Product Diversification and Grouping

Organize results by natural product categories rather than single-dimension ranking. For “jeans”, segment into trousers, jackets, shirts — mirroring physical retail organization.

Multi-Objective Optimization

Balance buyer and seller interests simultaneously: margin, stock levels, popularity, and customer preference signals.

Key Metrics

  • Product Exposure Rate (PER): product’s total views ÷ all product views across catalog. Identifies under/over-exposed items.
  • Product Net Profit Margin (PNPM): revenue minus all product costs ÷ revenue. Critical finding: high-exposure products typically have significantly lower profit margins.
