FAQPage Schema
How do I find the root cause of a drop in e-commerce category sales?

To find the root cause of a drop in e-commerce category sales, you decompose performance changes into traffic, conversion, basket size, and price/mix effects. This diagnostic analysis pinpoints whether reduced traffic or lower conversion drives the decline and suggests specific actions.

What is retail growth decomposition and how does it work?

Retail growth decomposition breaks down category revenue changes into traffic, conversion, basket, and price/mix effects. It further disaggregates price/mix into pure price, trade-up/down, size, and channel effects to identify exact performance drivers.

How do I diagnose subcategory and brand performance waterfalls?

To diagnose subcategory and brand performance waterfalls, you analyze category waterfalls to isolate specific underperforming subcategories or brands. This process generates root cause hypotheses and prioritizes targeted improvement levers for those segments.

Can I use retail analytics to separate pure price effects from trade-up/down behavior?

Yes, retail analytics can separate pure price effects from trade-up/down behavior by disaggregating the overall price/mix effect. This diagnostic analysis isolates pure price changes, size variations, trade-up/down shifts, and channel effects to explain revenue fluctuations.

What is the best way to identify actionable improvement levers for retail categories?

The best way to identify actionable improvement levers for retail categories is through deep diagnostic analysis that decomposes revenue drivers and maps them to root cause hypotheses. This structured narrative prioritizes specific levers to improve stagnating or declining sales.

When do I need diagnostic analysis for category performance?

You need diagnostic analysis for category performance when a retail or e-commerce category experiences unexpected growth, decline, or stagnation. It identifies the underlying root causes behind these performance changes to guide strategic interventions.
