Summary

Interviewed for a PM role at Meta and got hit with a metrics question about Facebook Videos. Pretty standard product analytics territory but the depth they expected was a bit more than I anticipated.

How would you determine whether Facebook Videos is successful?

Author's notes

I jumped straight to engagement metrics like watch time and shares, which felt right, but I could tell they wanted me to think harder about what 'success' actually means for a feature sitting inside a social platform.

Suggested Approach

Start by clarifying the goal of Facebook Videos (e.g., engagement, monetization, or ecosystem growth) and then define success using a mix of user, product, and business metrics. Structure your answer around a metrics framework like HEART or AARRR, and emphasize the importance of setting targets and segmenting by user types.

Pro tip: Tie your metrics to Facebook's overarching mission of bringing people closer together and its business model, and mention how you'd use A/B testing to validate causal impact rather than just correlation.

1. Clarify the goal

Ask clarifying questions to understand what Facebook Videos is trying to achieve (e.g., increase time spent, drive ad revenue, or foster community). This ensures your metrics align with the product's strategic intent.

2. Choose a metrics framework

Select a framework like HEART (Happiness, Engagement, Adoption, Retention, Task Success) or AARRR (Acquisition, Activation, Retention, Referral, Revenue) to organize your thinking and cover all aspects of success.

3. Define specific metrics

For each framework category, list concrete metrics (e.g., daily video views, watch time, uploads, shares, ad click-through rate, revenue per user). Prioritize a few key metrics that directly reflect the goal.

4. Set targets and benchmarks

Establish realistic targets based on historical data, industry benchmarks, or internal goals. Consider segmenting by user demographics, geography, and content type to get a nuanced view.

5. Measure and iterate

Explain how you would track these metrics over time, use A/B testing to establish causality, and iterate on product features to improve performance against the targets.

Key Points to Mention

  • North Star Metric: e.g., daily watch time or video engagement rate
  • HEART framework: Happiness, Engagement, Adoption, Retention, Task Success
  • AARRR funnel: Acquisition, Activation, Retention, Referral, Revenue
  • Leading vs. lagging indicators: e.g., uploads (leading) vs. revenue (lagging)
  • Segmentation: by user type (creator vs. viewer), geography, and content category
  • A/B testing and experimentation to validate causal impact of product changes
