Instagram Shops Guest Checkout Decision: Conversion vs. Fraud and Account Growth
Company: Meta
Role: Product Manager
Category: Product / Decision Making
Difficulty: medium
Interview Round: Other
You are a product manager for Instagram Shops, where businesses list products that people can browse and buy inside Instagram. Assume that today a shopper must be signed in to an Instagram account to complete a purchase. Decide whether Instagram should let people finish checkout without logging in first, and explain how you would reach, test and justify that decision.
```hint Who is actually logged out?
Before listing pros and cons, work out which people would reach checkout without being signed in and how much shopping they represent; the size and makeup of that group shapes everything after it.
```
### Clarifying Questions
- Where would a logged-out shopper come from: a product link shared in a message and opened in a mobile browser, a visitor arriving from search or an ad on the web, or an account holder whose session has expired?
- Does "without logging in" mean no identity step at all, or would a lightweight step such as an email or phone verification code still be acceptable?
- Which outcome matters most for this decision: sales for businesses and Instagram's commerce revenue, or growth in signed-in Instagram users?
- Should the change apply to every seller and market at once, or can it start with sellers who opt in, in one market?
### What a Strong Answer Covers
- The goals of Instagram Shops for buyers, sellers and Instagram, and where checkout without login supports or conflicts with each.
- Sizing the logged-out shopping audience, and its segments, before committing to build.
- Specific benefits and costs: conversion, account sign-ups, purchase data and personalization, fraud, and order support.
- An experiment that works for visitors who have no signed-in identity, with a primary metric, guardrails and a decision rule set in advance.
- A clear recommendation, including middle-ground options and the safeguards that come with them.
### Follow-up Questions
- Checkout completion rises in the test, but chargebacks on guest orders climb weeks later. What do you do?
- How would you randomize and analyze the experiment when the affected shoppers have no account ID?
- Large brands want checkout without login, while small sellers fear fraud. Would you let sellers opt in or out, and why?
