How to use it
Turn active and sold counts into a sourcing signal.
| Step | What to check | Why it matters |
|---|---|---|
| Start narrow | Model, brand, size, grade, or condition | Broad keywords can hide weak demand behind unrelated winners |
| Match the window | Compare 30-day active count to 30-day sold count | Mixing windows inflates or depresses the signal |
| Check margin last | Fees, shipping, returns, and cost of goods | Demand does not matter if the spread is too thin |
