Meta plans to launch a new video feature for young adults. How would you assess product-market fit and define success metrics?

To assess product-market fit for a new video feature targeting young adults, I would begin with user research to understand their current video consumption habits, unmet needs, and desired features. This would involve surveys, focus groups, and analyzing competitor offerings.

Key metrics for success would include:

• Engagement: Daily/monthly active users (DAU/MAU), average session duration, video completion rates, and interaction rates (likes, comments, shares).
• Retention: User churn rate, cohort retention over time, and repeat usage frequency.
• Acquisition: New user sign-ups driven by the feature, and cost per acquisition (CPA).
• Monetization (if applicable): Revenue generated through ads, subscriptions, or in-app purchases.
• User Satisfaction: Net Promoter Score (NPS) and user feedback through surveys and app store reviews.
