Clarifying Questions (3 minutes)

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

Why it matters: Seasonal fluctuations could explain the change without indicating a problem in the algorithm. Expected answer: No significant seasonal trend observed in previous years. Impact on approach: If seasonal, we'd focus on adjusting for cyclical patterns rather than algorithm issues.

• Considering the scope, I'm curious about user segments. Is this decrease uniform across all user groups or concentrated in specific segments?

Why it matters: Identifying affected segments could pinpoint specific issues or user behaviors. Expected answer: The decrease is more pronounced in certain user segments. Impact on approach: We'd investigate those segments' unique characteristics or recent changes affecting them.

• Thinking about recent changes, have there been any updates to the bidding algorithm or related systems in the past 1-2 months?

Why it matters: Recent changes could directly impact performance and provide a clear starting point for investigation. Expected answer: A minor update was implemented three weeks ago. Impact on approach: We'd focus on analyzing the impact of that specific update.

• Considering external factors, have there been any significant changes in the competitive landscape or market conditions?

Why it matters: External shifts could affect conversion rates independently of the algorithm's performance. Expected answer: No major market shifts, but some competitors have adjusted their strategies. Impact on approach: We'd analyze competitor actions and their potential impact on our performance.
