Start by clarifying the goal of ads on Reels: to monetize without harming user engagement. Then define success metrics across user, advertiser, and platform dimensions, and outline a measurement plan including guardrail metrics and experiments.
Pro tip: Emphasize the importance of balancing short-term revenue with long-term user retention, and propose a phased rollout with holdout groups to measure incremental impact.
Confirm the primary goal: monetization while maintaining or improving user experience. Identify key stakeholders and their success criteria.
Choose metrics across three categories: user engagement (e.g., time spent, retention), advertiser value (e.g., CTR, conversion rate), and platform revenue (e.g., ad revenue per user).
Identify metrics that should not degrade, such as user-reported satisfaction, churn rate, and content creation metrics.
Propose A/B tests with control groups, longitudinal studies, and cohort analysis to measure both short-term and long-term effects.
Outline how you would use data to refine ad formats, frequency, and targeting to improve both user and advertiser outcomes.
