Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be seasonality at play. Has this 20% decrease been adjusted for typical quarterly fluctuations?

Why it matters: Seasonal patterns could mask underlying issues or exaggerate the problem. Expected answer: The 20% decrease is already seasonally adjusted. Impact on approach: If not adjusted, we'd need to recalculate the true decrease.

• Considering the metric specificity, I'm curious about the definition of "retention." Are we measuring by number of advertisers, ad spend, or another metric?

Why it matters: Different retention metrics could point to different root causes. Expected answer: Retention is measured by the number of advertisers who placed at least one ad in the last 30 days. Impact on approach: This would focus our analysis on factors affecting advertiser activity rather than spend levels.

• Given the product's nature, I'm wondering about recent changes. Have there been any significant updates to the retargeting algorithm or user interface in the past quarter?

Why it matters: Product changes often impact user behavior and satisfaction. Expected answer: A new AI-driven targeting feature was rolled out two months ago. Impact on approach: We'd need to closely examine the impact of this feature on advertiser performance and satisfaction.

• Thinking about market dynamics, has there been any notable shift in competitor offerings or pricing structures recently?

Why it matters: Competitive pressures can significantly influence retention rates. Expected answer: A major competitor launched a new product with more aggressive pricing last month. Impact on approach: We'd need to assess our value proposition and pricing strategy in light of this competitive shift.
