What this question tests
Ability to define metrics for a commerce feature layered onto a social platform, covering discovery, conversion, and trust.
How to approach it
- Identify the funnel stages specific to shopping: product discovery within posts, product-detail engagement, and checkout completion.
- Pick a discovery metric: percent of shoppable posts that get a product-tag tap, reflecting whether the format is surfacing interest.
- Pick a conversion metric: checkout completion rate from tap-to-purchase, reflecting real commercial value, not just browsing.
- Pick a trust/quality metric: return or dispute rate on Instagram Shopping purchases, since trust in a new commerce surface is fragile early on.
- Add a supply-side metric: number of active sellers listing shoppable products, since growth caps out without enough merchant supply.
What a strong answer includes
- Covers the full funnel, discovery, conversion, trust, rather than a single engagement number.
- Includes a supply-side seller metric, correctly treating this as a marketplace, not just a feature.
- Names a trust/dispute guardrail, appropriate given commerce trust is harder-won than content engagement trust.
Common mistakes
- Naming only content-engagement metrics like likes or comments, missing the actual commerce funnel entirely.
- Ignoring seller/supply-side health, when a shopping feature is fundamentally a two-sided marketplace.
Likely follow-up questions
- Which of these five metrics would you prioritize as the single north star?
- How would you detect if shoppable posts are hurting organic content engagement?
