Scenario

Prompt
-
How would you determine whether adding Reels to the News Feed is
successful
?
-
What
metrics
would you define (primary + secondary/guardrails)?

experiment / launch plan
to measure impact?
Notes / Assumptions
-
The feed currently contains mixed content (text, images, long videos, links).

Reels may affect both
consumption
(viewing) and
distribution
(other content getting less exposure).
-
You have standard event logging for impressions, clicks, watch time, likes, comments, shares, hides, follows, etc.
