Others borrow Naver's search volume and pass it off as Coupang. RocketLens shows only the rank, search volume and sales it measured on Coupang itself — the ad-free organic top 40, one search away.

Most Korean tools stand in Naver search volume for Coupang demand. Measured side by side, the two diverge by 4x to 134x. RocketLens grades demand only from signals observed on Coupang, and when the sample is thin it says "collecting" instead of inventing a number.
Rank versus review count, price outliers and seller patterns are combined into a per-listing score. Read the market with the suspect band removed and both the average price and the real difficulty of entry change.
Sales are estimated from the increment in cumulative reviews. Next to each number we print how it was computed, how large the sample was and how many days it spans. What cannot be measured is left blank, never zero — zero means "none", not "unknown".
