Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be seasonality at play. Has this decline coincided with any particular season or event?

Why it matters: Seasonal trends can significantly impact user behavior and ad performance. Expected answer: The decline started in the summer months. Impact on approach: If seasonal, we'd need to compare year-over-year data and adjust our strategy accordingly.

• Considering user segments, I'm curious about the distribution of the decline. Is the 25% drop uniform across all user segments or more pronounced in specific groups?

Why it matters: Understanding which segments are most affected can help pinpoint the root cause and tailor solutions. Expected answer: The decline is more significant among newer users. Impact on approach: We'd focus on onboarding and early user experience if newer users are disproportionately affected.

• Thinking about recent changes, have there been any updates to the ad creatives or placement within the games?

Why it matters: Changes in ad content or positioning can dramatically affect CTR. Expected answer: No significant changes to ad creatives or placement. Impact on approach: If no changes were made, we'd need to look at external factors or gradual shifts in user behavior.

• Considering the broader ecosystem, has there been any change in the mix of games where these ads are shown?

Why it matters: Different game genres or styles might have varying ad performance. Expected answer: The game mix has remained relatively stable. Impact on approach: If the mix is stable, we'd need to investigate changes in user behavior or ad fatigue within existing games.

• Focusing on measurement accuracy, has there been any change in the way CTR is calculated or tracked?

Why it matters: Ensuring consistent measurement is crucial for accurate problem identification. Expected answer: No changes in CTR calculation or tracking methods. Impact on approach: If measurement is consistent, we can confidently focus on actual performance issues rather than data anomalies.
