In establishing success metrics for Facebook Dating, I would focus on three primary areas: user acquisition, user engagement and satisfaction, and monetization: User Acquisition : Assess the effectiveness of our marketing strategies and campaigns by monitoring the influx of new users. Identify which channels—such as social media, referrals, and organic search—are the most successful. User Engagement & Satisfaction : The count of active users (daily, weekly, monthly) will indicate the level of engagement. Moreover, tracking the average session duration and usage frequency will provide further insights. It's also essential to implement a user satisfaction survey or Net Promoter Score (NPS) to gauge user sentiment and satisfaction levels. Monetization : This aspect will focus on revenue generation, average revenue per user (ARPU), and the conversion rates from free to premium users. Understanding these metrics is vital for ensuring the financial viability of Facebook Dating. Ultimately, the aim is to create a relevant and engaging dating platform for users, and these metrics will assist in monitoring our progress toward that objective.
