Facebook wants to split its newsfeed into two. What metrics would you look at to validate this decision?

Introduction

Splitting Facebook's newsfeed into two is a significant product decision that requires careful consideration of success metrics. To approach this product success metrics problem effectively, I will follow a simple product success metric framework. I'll cover core metrics, supporting indicators, and risk factors while considering all key stakeholders.

Step 1

Product Context

Facebook's newsfeed is the core feature of the platform, displaying a personalized stream of content from friends, pages, and advertisers. Splitting it into two separate feeds represents a major shift in user experience and content distribution.

Key stakeholders include:

• Users: Seeking engaging content and connections
• Advertisers: Looking for effective ad placement and reach
• Content creators: Aiming for visibility and engagement
• Facebook: Balancing user satisfaction, engagement, and revenue

User flow:

1. User opens Facebook app/website
2. They're presented with two distinct feed options
3. User chooses which feed to browse
4. User scrolls, interacts with content, and switches between feeds as desired

This change aligns with Facebook's strategy to combat misinformation and improve user experience by potentially separating personal and public content. Competitors like Twitter have experimented with similar concepts (e.g., "For You" and "Following" tabs).

Product Lifecycle Stage: Mature product undergoing significant redesign

Software-specific context:

• Platform: Mobile apps (iOS/Android) and web
