15 Key Consumer Behavior Metrics to Analyze for Optimizing User Experience on Your Peer-to-Peer Marketplace Platform

Importance: Longer sessions usually mean higher engagement; extremely long durations can signal usability issues.
Key metrics: Average session length, pages per session, feature-specific time spent.

6. Listing Interaction Rates

Track buyer interactions with listings, including views, favorites, shares, and inquiries, as well as seller responses.

Importance: Directs UX improvements where users face friction.
Key metrics: Bounce rates on key pages, cart and listing abandonment rates.

10. Repeat Usage and Retention Rates
