What this question tests
Tests goal-setting for a strategically important but competitively pressured product, requiring goals tied to both user value and Meta's competitive position against TikTok.
How to approach it
- Clarify the strategic context: Reels exists largely to retain short-form video attention that would otherwise go to TikTok, so goals must reflect competitive retention.
- Propose growing Reels' share of total time spent on Instagram, since this reflects whether short-form video is successfully capturing attention within the app.
- Propose improving creator monetization and tools, since Reels' long-term supply of quality content depends on creators finding it worthwhile relative to competitors.
- Propose increasing Reels-driven session frequency, a sign Reels is becoming a habitual reason to open Instagram, not just a passive feed component.
- Add a guardrail: watch time increases shouldn't come from cannibalizing higher-monetizing Feed or Stories ad inventory without a net-positive revenue impact.
- Prioritize and sequence: in the near term, prioritize engagement and retention goals over monetization, since Reels needs to win attention first.
What a strong answer includes
- Frames goals around the real competitive context, defending against TikTok, rather than generic grow-engagement language.
- Names creator monetization as a goal, correctly identifying supply-side health as critical to Reels' long-term competitiveness.
- Adds a revenue cannibalization guardrail, showing awareness that Reels' growth isn't free if it steals from higher-margin ad formats.
- Sequences goals logically, engagement before monetization, reflecting a realistic maturity curve for a still-scaling product.
Common mistakes
- Setting a generic increase-watch-time goal without tying it to the actual competitive threat from TikTok.
- Ignoring the creator side entirely, focusing only on viewer-facing metrics for a product whose supply depends on creator incentives.
