Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent change in the product or marketing strategy. Has there been any significant update to the free trial offering or its promotion in the past month?

Why it matters: Recent changes often correlate with sudden metric shifts. Expected answer: Yes, we updated the trial landing page design. Impact on approach: If confirmed, I'd focus on analyzing the new design's impact on user behavior.

• Considering the specificity of the 15% drop, I'm curious about the baseline. What was the average daily signup rate for the free trial in the month before this drop occurred?

Why it matters: Understanding the baseline helps quantify the impact and identify anomalies. Expected answer: Around 1000 signups per day. Impact on approach: This would help determine if the drop is statistically significant or within normal fluctuations.

• Given that this is a free trial, I'm wondering about the user acquisition channels. Has there been any change in the distribution of traffic sources (organic search, paid ads, referrals) leading to the trial signup page?

Why it matters: Changes in traffic sources can significantly impact conversion rates. Expected answer: We've seen a decrease in paid ad traffic due to budget adjustments. Impact on approach: If confirmed, I'd investigate the quality and conversion rates of different traffic sources.

• Considering PagerDuty's target audience, I'm thinking about potential seasonal factors. Are there any known industry events or cycles that typically affect signup rates during this time of year?

Why it matters: Seasonal trends can explain temporary fluctuations in metrics. Expected answer: No significant seasonal events, but there's an ongoing tech conference. Impact on approach: If seasonal factors are at play, I'd adjust the analysis to account for expected variations.
