Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a seasonal trend. Has this drop coincided with any major holidays or events?

Why it matters: Seasonal fluctuations could explain the CTR drop and inform our solution approach. Expected answer: No significant seasonal events during this period. Impact on approach: If seasonal, we'd focus on adjusting expectations and strategies for known cyclical patterns.

• Considering user segments, I'm curious if this drop is uniform across all demographics. Have you noticed any particular user groups 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 relatively uniform across segments. Impact on approach: If uniform, we'd look at system-wide issues; if segmented, we'd focus on specific user group needs.

• Thinking about recent changes, have there been any updates to the ad serving algorithm or content matching in the past month?

Why it matters: Recent changes could directly impact CTR performance. Expected answer: Minor updates to the content matching algorithm were implemented. Impact on approach: If changes occurred, we'd scrutinize their impact and potentially roll back or optimize them.

• Regarding measurement accuracy, has there been any change in how CTR is calculated or tracked across publisher sites?

Why it matters: Ensures we're comparing apples to apples and not dealing with a data anomaly. Expected answer: No changes to CTR calculation methods. Impact on approach: If calculation methods changed, we'd need to recalibrate our analysis based on the new methodology.
