Evaluates Facebook Memories feature performance beyond click-through rate and surface-level engagement. Strong answers measure incremental engagement, retention, cannibalization, quality guardrails, frequency caps, sensitive-content handling, and launch criteria.

Scenario: The Memories feature resurfaces old posts to spark nostalgia and engagement. Recent data shows mixed click‑through rates and questions about whether it inflates time‑spent or simply reshuffles attention. You must propose an evaluation framework, decide acceptable CTR thresholds, and ensure content is not resurfaced too frequently.

​

Question 1: Outline a framework to evaluate the performance of the Facebook Memories feature. (Hint: retention, depth of interaction, share rate)

Question 2: Is a 20 % click‑through rate acceptable for Memories? Explain how you would benchmark it. (Hint: industry norms, impression volume, user intent)

Question 3: Is total time‑spent a good metric for Memories’ impact? Why or why not? (Hint: attribution challenges, alternative metrics)

Question 4: After resurfacing a 2019 post in 2020, how would you prevent it appearing again in 2021? (Hint: deduping strategy, cool‑down windows)
