Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent product update. Has there been any significant change to the deep linking feature or related systems in the past 1-2 months?

Why it matters: Recent changes could directly impact functionality. Expected answer: Yes, there was a minor update to the SDK. Impact on approach: If yes, we'd focus on the update's impact; if no, we'd look at external factors.

• Considering user segments, I'm curious about the distribution of the drop. Is the 20% decrease uniform across all user segments, or are certain groups more affected?

Why it matters: Helps identify if it's a global issue or specific to certain users. Expected answer: The drop is more pronounced in mobile users. Impact on approach: If segmented, we'd focus on the most affected groups; if uniform, we'd look at broader issues.

• Thinking about the metric itself, has there been any change in how click-through rates are measured or reported in the last month?

Why it matters: Ensures we're comparing apples to apples in our data. Expected answer: No changes in measurement. Impact on approach: If changed, we'd need to adjust our analysis; if not, we can proceed with current data.

• Considering external factors, have there been any significant changes in the competitive landscape or market conditions that might affect user behavior?

Why it matters: External factors could explain the drop without internal issues. Expected answer: No major market shifts noted. Impact on approach: If yes, we'd factor in market conditions; if no, we'd focus more on internal factors.
