Success Metrics for Podcasts on Netflix: North Star, Guardrails, Cannibalization

You are a product manager at Netflix. Netflix Podcasts went live six months ago. How would you define success for this launch, and how would you measure whether it is succeeding? ```hint Start from why a video service wants audio Before listing metrics, decide what podcasts are meant to do for a subscription business like Netflix's. Six months in, the real question is whether the bet is working, not whether it has already paid for itself. ``` ### Clarifying Questions - Do podcasts live inside the existing Netflix app for current subscribers, in a separate app, or are they open to non-subscribers too? - Is the catalog Netflix's own shows built around its films and series, licensed third-party podcasts, or both, and are the episodes audio, video or both? - Did the launch reach every market and plan, including the ad-supported plan, or only some of them? - Was a goal set at launch, such as keeping subscribers engaged, attracting new ones, or opening a new advertising line? ### What a Strong Answer Covers - A goal for podcasts tied to how Netflix makes money, with a reason for choosing it over the alternatives - A listener journey from discovering podcasts to listening habitually, which the metrics follow stage by stage - One north-star metric suited to a six-month-old launch, supported by adoption, depth and repeat-use metrics - Guardrails for cannibalized video viewing, subscriber churn and content cost, plus a way to attribute impact that avoids comparing self-selected listeners with everyone else - What results at six months would justify investing more, changing course or winding the product down ### Follow-up Questions - Podcast listeners churn less than non-listeners. How would you tell whether podcasts caused that or whether loyal subscribers simply try more features? - Listening time keeps rising, but the total time each subscriber spends with Netflix has not moved. Is that a success or a warning sign? - If leadership later wanted podcasts to earn advertising revenue on the ad-supported plan, how would your metrics change?
