Suggested Approach

Start by clarifying the goal of the dashboard (e.g., measuring launch campaign effectiveness on TikTok) and the target audience (Apple's marketing team). Then, structure your answer around a funnel framework—awareness, engagement, conversion, and retention—and select key metrics for each stage, explaining their relevance to Apple's objectives.

Pro tip: Emphasize that metrics should be actionable and tied to business outcomes; for example, don't just list views, but explain how view-through rate informs creative strategy. Also, mention the importance of benchmarking against previous launches or industry standards.

1. Clarify Objectives and Audience

Ask clarifying questions to understand the primary goal (e.g., brand awareness, pre-orders, sales) and who will use the dashboard (e.g., marketing, product team). This ensures metrics align with business needs.

2. Map the User Journey

Outline the stages a TikTok user goes through from seeing the ad to taking action: awareness, engagement, conversion, and retention. This provides a logical structure for metrics.

3. Select Key Metrics per Stage

Choose 1-2 metrics for each stage that are most relevant to Apple's goals. For example, impressions and reach for awareness; engagement rate and average watch time for engagement; click-through rate and conversion rate for conversion; repeat engagement or brand lift for retention.

4. Explain Why Each Metric Matters

For each metric, articulate its significance: how it indicates performance, what decisions it informs, and how it connects to broader business objectives like sales or brand perception.

5. Prioritize and Summarize

If time permits, prioritize the most critical metrics and summarize how they collectively provide a holistic view of launch performance, enabling data-driven optimization.

Actionability: how each metric informs creative optimization, targeting, or budget allocation
Benchmarking: compare against previous Apple launches or industry benchmarks
Attribution: challenges in measuring conversion due to cross-device behavior, and potential solutions like TikTok's pixel or promo codes
