Challenger Search Engine vs. Google and Bing: A Program That Earns User Loyalty
Company: Google
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
You are a product manager at a search engine that competes with Google and Bing, and you are asked to create a loyalty program for it. Explain what the program should achieve, who it is for, how it works, and how you would know whether it is succeeding.
```hint Price a loyal user
Before choosing perks, work out what keeps people on an incumbent search engine and roughly what a retained user is worth to yours, so the program's rewards have both a purpose and a ceiling.
```
### Clarifying Questions
- Is this a new, small engine trying to win its first users, or an established one with a meaningful user base that it wants to keep?
- Is the program's main job to attract users, to keep them from drifting back to an incumbent, or to increase how often they search?
- Does the engine make its money from search ads like the incumbents, or from another model?
- Is the program for people who search, or should it also cover advertisers?
### What a Strong Answer Covers
- A clear goal for the program and how it ties to the way the engine earns money
- Candidate user segments compared, with one chosen based on who would realistically change a search habit
- Program mechanics (what earns rewards, what users can redeem, any status or non-cash perks) and why each one rewards the intended behavior
- The abuse, cost and advertiser-trust risks that come from rewarding search activity, and how the design handles them
- Metrics that separate real, incremental loyalty from reward-chasing, with cost and quality guardrails
### Follow-up Questions
- If an incumbent copied your program within months, what part of it would still give you an edge?
- How would you tell users who are loyal to the engine apart from users who are loyal only to the rewards?
- How would advertisers view traffic from rewarded users, and what would you do to keep their trust?
Overview: A product design question on creating a loyalty program for a search engine that competes with Google and Bing. It tests whether you can set a goal for the program, pick a target segment, design earning and redemption mechanics that build a lasting habit, control abuse and cost, and measure incremental loyalty.
