What metrics would you track for a social sharing feature?
Model answer
Model answerA sharing feature has two sides: the sharer and the recipient. For sharers: share rate, share completion rate, and repeat share rate. For recipients: click-through rate on shared links and sign-up conversion from shared links. The most important metric is viral coefficient — if each user generates more than one new user through sharing, growth becomes self-sustaining.
