• Looking at the timing, I'm thinking there might be a recent platform change. Has eBay implemented any significant updates to the seller registration process in the last month?

Why it matters: Recent changes could directly impact new seller onboarding. Expected answer: Yes, there was a UI update to the registration flow. Impact on approach: If confirmed, we'd focus on analyzing the new UI's impact on conversion rates.

• Considering potential seasonal factors, is this 30% decrease unusual compared to the same period in previous years?

Why it matters: Helps distinguish between cyclical trends and genuine problems. Expected answer: This decrease is abnormal for this time of year. Impact on approach: If confirmed, we'd rule out seasonality and focus on recent changes or external factors.

• I'm curious about the geographic distribution. Is this decrease uniform across all regions, or are certain areas more affected?

Why it matters: Localized issues might indicate region-specific problems or competition. Expected answer: The decrease is more pronounced in certain regions. Impact on approach: We'd investigate region-specific factors and potentially implement targeted solutions.

• Thinking about user segments, are we seeing this decrease across all seller categories, or is it more prevalent among specific types of sellers?
