Suggested Approach

Start by clarifying the goal of Instagram's search feature and the user problems it solves, then define success metrics across user engagement, satisfaction, and business impact. Structure your answer by mapping metrics to the user journey (query, results, click-through, satisfaction) and prioritize a north-star metric with supporting guardrails.

Pro tip: Tie your metrics to Instagram's strategic priorities (e.g., increasing time spent, creator discovery, or shopping) and contrast with TikTok's search approach to show you understand the competitive landscape and can think like a TikTok PM.

1. Clarify goals and scope

Ask clarifying questions to understand what 'success' means for Instagram search (e.g., user engagement, monetization, or ecosystem health) and which user segments are most important.

2. Define the user journey

Map the search experience from query entry to result consumption, identifying key moments where success can be measured (e.g., query success rate, click-through, time to result).

3. Choose a north-star metric

Select a single metric that best captures the core value of search, such as 'successful search sessions per user' or 'search-driven engagement rate'.

4. Select supporting metrics

Identify metrics across engagement (DAU/MAU of search, queries per user), quality (zero-result rate, reformulation rate), and satisfaction (CSAT, task success rate).

5. Consider business impact and guardrails

Include metrics like search-driven revenue, ad clicks, or content discovery, and set guardrails to ensure improvements don't harm other areas (e.g., app performance, privacy).

Key Points to Mention

  • North-star metric: e.g., successful search sessions per user or search-driven engagement rate
  • Engagement metrics: daily/weekly search users, queries per user, click-through rate on results
  • Quality metrics: zero-result rate, query reformulation rate, time to first click
  • Satisfaction metrics: CSAT for search, task success rate, user feedback
  • Business metrics: search-driven revenue, ad impressions, content discovery (e.g., new creators followed)
  • Guardrail metrics: app load time, privacy concerns, impact on other features
