Build a Health Scorecard for LinkedIn: North Star, Funnel and Guardrail Metrics

You are asked to judge how well LinkedIn, the professional networking platform, is doing as a whole. Which metrics would you rely on? Lay out the set you would track, pick the one you would treat as the main measure of success, and explain what you would watch alongside it so that this number cannot improve at the expense of members or paying customers. ```hint Follow the value LinkedIn earns money from hirers, advertisers and paying subscribers, and each of them pays because of what members do on the platform. Trace how value moves between these groups before you choose the number at the center. ``` ### Clarifying Questions - Should the evaluation cover LinkedIn's paid lines (hiring tools, advertising, Premium, learning), or only the free member experience? - Is the priority member engagement, the health of the network itself, or revenue? - Should I treat LinkedIn as a mature network where most target professionals already have an account, or focus on markets where it is still adding many members? - Which members matter most here: active job seekers, professionals who mostly read their feed, or people who post? ### What a Strong Answer Covers - The value LinkedIn creates for members, hirers, marketers and paying subscribers, and how each side depends on the others - Metrics along the member journey from sign-up to retention, plus outcome metrics for each paying side, each with a precise definition - One north-star metric, justified against alternatives such as registered members, daily active users or time spent - Guardrails against engagement that harms trust or the member experience - How cohorts, member segments and hiring-market cycles affect the way the numbers are read ### Follow-up Questions - A change that sends members more notifications lifts weekly activity. How would you tell whether members are getting more value or are just being pulled back? - A job seeker who lands a role through LinkedIn usually becomes less active afterward. How should your metrics treat that? - Hiring slows across the economy and job applications fall. How would you judge whether LinkedIn's hiring products are still healthy?
