My first instinct was to jump straight into funnel drop-off analysis, which I think was okay but I skipped past the step of actually defining what 'conversion' means in this context.
Start by clarifying the metric definition and scope—sitewide conversion rate could be affected by traffic mix, seasonality, or product changes. Then systematically segment the data to isolate the root cause, considering both technical and business factors, and propose a hypothesis-driven investigation plan.
Pro tip: Mention that you would check for instrumentation or tracking changes first, as a sudden drop often stems from data quality issues rather than actual user behavior. Also, consider external factors like competitor launches or macroeconomic trends that could impact conversion.
Define what 'sitewide conversion rate' means (e.g., sessions to orders, users to purchases) and confirm the time frame and segments (e.g., all platforms, regions). Ensure you understand how the metric is calculated and whether any recent changes in tracking could affect it.
Break down conversion rate by dimensions such as device type, traffic source, geography, new vs. returning users, and product category. Look for segments with the largest declines to narrow down the problem area.
Examine each step of the conversion funnel (e.g., product view, add to cart, checkout initiation, purchase) to identify where the drop-off occurs. Compare funnel metrics year over year to pinpoint the stage with the most significant change.
Check for technical issues like site performance, bugs, or A/B tests that could impact conversion. Also consider business factors such as pricing changes, promotions, inventory availability, and competitor actions.
Based on the segmentation and funnel analysis, develop hypotheses about the root cause. Validate them with additional data (e.g., user surveys, session recordings) and, if possible, run experiments to confirm causality.
