Suggested Approach

Start by clarifying the goal of Facebook Stories—whether it's driving engagement, monetization, or user retention—and then define success metrics aligned with Meta's business model. Structure your answer around a metrics framework that covers user acquisition, engagement, retention, and monetization, while considering the unique ephemeral nature of Stories. Finally, prioritize metrics and discuss trade-offs, emphasizing how you'd avoid vanity metrics.

Pro tip: Differentiate between leading and lagging indicators, and highlight the importance of measuring incremental value—e.g., how Stories drives additional engagement beyond Feed—to avoid double-counting and show strategic thinking.

1. Clarify the goal and scope

Ask clarifying questions to understand whether the focus is on user growth, engagement, monetization, or ecosystem health. Confirm the time horizon and any constraints.

2. Define success metrics across the funnel

Identify metrics for acquisition (e.g., DAU/MAU), engagement (e.g., daily stories created/viewed, time spent), retention (e.g., 7-day retention of story creators/viewers), and monetization (e.g., ad revenue, ARPU).

3. Prioritize and set targets

Select the top 2-3 metrics that best indicate success, and propose specific targets or benchmarks (e.g., increase daily story creation by X%). Explain why these matter most.

4. Consider trade-offs and guardrail metrics

Discuss potential negative impacts, such as cannibalization of Feed or user fatigue, and suggest guardrail metrics (e.g., overall time spent, user satisfaction) to monitor.

5. Outline measurement and iteration plan

Describe how you'd track these metrics (e.g., A/B tests, dashboards) and how you'd iterate based on data, emphasizing a test-and-learn approach.

Key Points to Mention

  • North Star Metric: Daily Active Story Creators or Viewers, as it captures both engagement and content supply.
  • Engagement metrics: Stories created per user, views per story, completion rate, and time spent viewing Stories.
  • Retention metrics: 7-day and 30-day retention for users who create or view Stories, compared to non-users.
  • Monetization metrics: Ad revenue per user, ad completion rate, and click-through rate on story ads.
  • Incremental value: Measure lift in overall engagement and revenue attributable to Stories, not just absolute numbers.
  • Guardrail metrics: Overall time spent on Facebook, user-reported satisfaction, and Feed engagement to detect cannibalization.
