Instagram Shopping Tab: Post-Launch Evaluation and Sizing

Context

You are evaluating the success of a new Instagram Shopping Tab after launch. The goal is to measure whether it drives incremental commerce value while maintaining a healthy user and merchant experience and not harming core engagement or ads revenue.

Questions

Primary and Secondary Metrics
- What primary success metrics and guardrail/secondary metrics would you track to determine the Shopping Tab’s success?
Pre-Launch Sizing
- How would you estimate the expected impact before launch (e.g., using TAM × adoption × ARPU assumptions)?
Monitoring & Dashboards
- Describe or sketch the dashboards/plots you would build to monitor these metrics over time and during ramp/experiments.

Hints

Think funnel conversion, GMV, click-through, retention.
Size via TAM × adoption × ARPU; incorporate cannibalization and ramp scenarios.
