Summary

PM interview at Google, one question about YouTube metrics. Short and focused, nothing too wild, but these deceptively open-ended questions have a way of going sideways fast.

Q1

If you were the PM for YouTube, what metrics would you prioritize and why?

Author's notes

I went straight for engagement metrics like watch time and DAU, which felt right, but I didn't spend enough time segmenting by user type or thinking about creator-side health.

Suggested Approach

Start by clarifying YouTube's mission and business model, then segment metrics into a balanced framework (e.g., user, creator, and business). Prioritize 2-3 north star metrics with clear rationale, and explain how they ladder up to company goals.

Pro tip: Show you understand trade-offs by acknowledging that optimizing for watch time alone can hurt creator diversity or user well-being; propose guardrail metrics to balance growth with ecosystem health.

1. Clarify context and goals

Restate YouTube's mission (give everyone a voice and show them the world) and key business drivers (ads, subscriptions, creator ecosystem). This sets the stage for metric selection.

2. Segment metrics by stakeholder

Group metrics into user (engagement, satisfaction), creator (supply, monetization), and business (revenue, profitability). This ensures a holistic view.

3. Prioritize 2-3 north star metrics

Select metrics that best capture value creation, such as watch time (user value) and creator revenue (ecosystem health). Explain why they matter most.

4. Define supporting and guardrail metrics

List input metrics (e.g., DAU, uploads) that drive north stars, and guardrails (e.g., user-reported satisfaction, content diversity) to prevent negative side effects.

5. Connect to strategy and iterate

Explain how these metrics inform product decisions, and mention the need to revisit as the platform evolves (e.g., shorts vs. long-form).

Key Points to Mention

  • Watch time as a proxy for user value and ad revenue potential
  • Creator ecosystem health: number of active creators, creator revenue, and upload diversity
  • User engagement metrics: DAU/MAU, session length, and retention
  • Business metrics: ad revenue per user, subscription growth (YouTube Premium), and profitability
  • Guardrail metrics: user well-being (e.g., time spent vs. satisfaction), content moderation, and regulatory compliance
  • Trade-offs between short-term growth and long-term ecosystem sustainability
