Feed-Ranking Strategy: Friends vs. Stranger Content

Background

A personalized feed currently mixes posts from users' friends and posts from unconnected accounts ("strangers"). Observational data suggests users exhibit more social behavior (e.g., comments, shares, replies, messages) when viewing friends’ posts. The product team is considering surfacing a higher proportion of stranger content to increase discovery.

Task

Would you increase the proportion of stranger posts in the feed? Outline how you would evaluate and decide.

Requirements

State clear hypotheses and mechanisms.
Define success metrics, guardrails, and decision criteria.
Propose an experiment design (including dosage levels, duration, and power).
Specify key user and market segments to analyze.
Discuss trade-offs (e.g., engagement vs. discovery) and long-term effects.
