Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a seasonal trend. Has this 15% drop been compared to the same period last year?

Why it matters: Seasonal fluctuations could explain the decrease without indicating a deeper issue. Expected answer: No significant seasonal trend observed in previous years. Impact on approach: If seasonal, we'd focus on adapting to cyclical patterns rather than fixing a problem.

• Considering user segments, I'm curious if this drop is uniform across all user groups. Have you noticed any particular demographic or geographic segment more affected than others?

Why it matters: Identifying specific affected segments could point to targeted issues or changes in user behavior. Expected answer: The drop is more pronounced in younger users aged 18-24. Impact on approach: We'd focus on understanding changes in younger users' preferences or behaviors.

• Thinking about recent changes, has there been any update to the ad content, design, or placement in the last 1-2 months?

Why it matters: Recent changes could directly impact user engagement with the ads. Expected answer: A minor UI update was implemented 6 weeks ago. Impact on approach: We'd investigate the impact of the UI change on ad visibility and user interaction.

• Considering technical aspects, has there been any change in how click-through rates are measured or reported?

Why it matters: Ensures we're comparing apples to apples and not dealing with a measurement issue. Expected answer: No changes in measurement or reporting systems. Impact on approach: Confirms the issue is with actual performance, not data collection.
