How would you improve Facebook Search?

Introduction

I'm excited to dive into improving Facebook Search. This is a critical feature that impacts billions of users daily, serving as a gateway to content discovery and user engagement across the platform. I'll approach this challenge by first clarifying our objectives, then analyzing user segments and pain points, before proposing and evaluating solutions. Let's get started.

Step 1

Clarifying Questions (5 mins)

• What specific metrics or KPIs are we looking to improve with Facebook Search?

Why this matters: Understanding our goals will guide our improvement strategy. Hypothetical answer: We aim to increase daily active users (DAU) of search by 20% and improve search result relevance by 15% within six months. Impact: This focuses our efforts on user engagement and search quality.

• What are the current top use cases for Facebook Search?

Why this matters: Identifying primary use cases helps prioritize improvements. Hypothetical answer: Top use cases include finding friends/people, searching for posts/content, and discovering groups/pages. Impact: We'll focus on enhancing these core functionalities first.

• Are there any technical limitations or ongoing projects that might affect our approach?

Why this matters: Technical constraints can influence solution feasibility. Hypothetical answer: We're currently migrating to a new search indexing system, which will be completed in three months. Impact: We'll need to consider this transition in our timeline and proposed solutions.

• How does Facebook Search currently compare to competitors like Google or Twitter in terms of user satisfaction?

Why this matters: Benchmarking against competitors helps identify areas for improvement. Hypothetical answer: Facebook Search lags behind Google in general web search but outperforms Twitter in social content search. Impact: We'll focus on leveraging Facebook's unique social graph for differentiation.

Based on these answers, I'll assume that:

1. Our primary goal is to increase user engagement with search while improving relevance.
2. We'll focus on enhancing core use cases: people, content, and group/page discovery.
3. We have a 3-month window before a new indexing system is in place, which may enable more advanced features.
4. Our competitive advantage lies in leveraging Facebook's social graph for search.
