How would you approach optimizing a marketing campaign that has underperformed at ByteDance?
Structure your response as a practical analytics and product improvement plan. Explain how you would diagnose the performance gap, determine whether the issue is targeting, creative, placement, bidding, funnel friction, measurement, or external factors, and prioritize actions. Use relevant ByteDance surfaces such as TikTok Ads Manager, TikTok, or CapCut where appropriate. Define the data you would request, the metrics you would monitor, the experiments you would run, and the criteria for scaling, revising, or stopping the campaign. Address trade-offs between short-term efficiency, reach, learning, and user experience.
