Clarifying Questions (3 minutes)

• Given the sudden drop, I'm wondering about recent changes. Have there been any significant updates to the edX platform or course offerings in the past month?

Why it matters: Recent changes could directly impact search visibility or user behavior. Expected answer: Yes, a new UI was rolled out two weeks ago. Impact on approach: If confirmed, we'd focus on UI-related hypotheses and user experience analysis.

• Considering the specificity to organic search, I'm curious about search engine algorithm updates. Has there been any notable change in our search engine rankings or visibility recently?

Why it matters: Search algorithm changes can dramatically affect organic traffic. Expected answer: No major known algorithm updates, but rankings have dropped for some key terms. Impact on approach: We'd prioritize SEO-related hypotheses and competitor analysis.

• Looking at the user journey, I'm thinking about potential changes in user behavior. Has there been any shift in the conversion rate from organic search visits to course enrollment?

Why it matters: This helps distinguish between traffic issues and conversion problems. Expected answer: Conversion rates have remained stable. Impact on approach: We'd focus more on traffic acquisition rather than on-site conversion optimization.

• Considering the broader context, I'm wondering about seasonal patterns. Is this 30% drop unusual compared to historical data for this time of year?

Why it matters: Helps differentiate between cyclical patterns and genuine problems. Expected answer: This drop is significantly larger than typical seasonal variations. Impact on approach: We'd rule out seasonality and focus on recent changes or external factors.
