Success Metrics for Launching Live Video Broadcasting on LinkedIn (2018)

It is 2018, and you are the LinkedIn product manager launching live video broadcasting on the platform. How would you decide whether the launch succeeded? ```hint Two sides have to work Live video needs people and Pages willing to broadcast and members willing to show up and watch. Define what success means for each side and for LinkedIn as a professional network before choosing a metric. ``` ### Clarifying Questions - Who can broadcast at launch: any member, a selected group of creators and company Pages, or both? - Is the main goal deeper engagement on LinkedIn, a stronger way for companies and creators to reach audiences, or future revenue from events and advertising? - Over what horizon should success be judged: the first weeks after launch or the first several months? - Do replays watched after a broadcast ends count toward success, or only live viewing? ### What a Strong Answer Covers - Goals for live video grounded in LinkedIn's professional purpose, stated separately for broadcasters, viewers and LinkedIn - A north-star metric with a clear rationale, plus supporting metrics across the broadcaster and viewer funnels - Guardrails for cannibalization of other feed content, notification fatigue, stream quality and content safety - How impact is attributed despite network effects, and what targets set in advance count as success - How the metric mix shifts from a limited beta to a broad rollout ### Follow-up Questions - Watch time rises but comments per viewer fall. How do you read that, and what would you do? - How would you set a first-quarter target when LinkedIn has no history for live video? - A broadcaster's audience depends on their followers. How would you tell whether weak viewing comes from poor content or poor distribution?
