From the author

Run a nine-checkpoint screen on a candidate product niche — long- and short-term demand trend, a competition-density ratio, brand concentration among top listings, fulfillment-method mix, price-band distribution, listing-age composition, and new-entrant share with its review/rating threshold — before committing to sourcing. Produces a structured multi-signal read instead of a single-metric judgment call. Use for 新类目值不值得进、选品前系统性验证、判断类目是否有新卖家机会、避免只看销量就选品. Do not use as the sole gate for a sourcing decision without also checking unit economics, IP/compliance risk, and supplier feasibility.
