Coupang does not tell you what changed overnight. RocketLens reads 434 category boards every morning and writes it down here.
Opportunity shows up in three places every morning
Your rank, your Item Winner, today's risers. RocketLens covers all three each morning.
Still searching keyword by keyword to see your rank?
RocketLens records the ad-free top 40 for every keyword daily and shows what fell first. One look each morning, and you are done.
Track my rank Your winnerIf your sales tell you the Item Winner is gone, it is already too late
RocketLens checks the holder every 30 minutes and alerts you the moment it changes. Hear it from the alert, not from halved sales.
Turn on winner alerts Today's risersProducts picked on a hunch become inventory

See today's risersEvery number here came out of Coupang
Numbers pulled from inside Coupang, not Naver search volume. Four lines say where each one comes from.
Pulled from the Coupang app daily
449 category bestseller boards, taken from the Coupang app once a day as they are. Sales order with no ads mixed in.
Search volume counted from Coupang views
Computed backwards from Coupang product views and click-through. Given as a grade, not a hard number.
Sales estimated from review growth
Review growth times a multiplier. It is an estimate, and the method sits next to the number.
Unmeasured values stay blank
A zero reads as 'does not sell'. What we could not measure stays blank, with a note on when we measure again.
Check whether the category is an opportunity before you enter
Enter a category Rocket delivery already owns and you only burn ad money. RocketLens alone computes the Rocket share, seller listings, and bottom-quarter reviews of the top 20 for every category, every day.
Work out how many a day it takes to hold on
We count how many units a day the bottom bestseller sells. Put your own daily sales next to it. Products that gain no reviews stay blank.

Frequently asked questions
- Is that search volume actually Naver's?
- It is worked backwards from Coupang product views and click-through. Everything in the demand column comes from inside Coupang. Where the sample is thin we leave the grade blank.
- Do I need an account?
- Keyword reports open five times a day without one. The category bestseller boards are not counted at all. Rank tracking and winner alerts need an account, because those screens are a record that builds up over days.
- How often is rank measured again?
- Once a day. A climb at 10am that fell back by 4pm is one we miss too. Only the Item Winner is checked every 30 minutes.
- How is the sales number produced?
- Reviews gained, multiplied by a factor. It is an estimate. Coupang does not publish unit sales, so an estimate is as far as we will go. A product nobody reviews stays blank.
- When do I pay?
- Open it free, and buy a 30-day pass only in the months you need one. Nothing is set to auto-renew.
The boards come in again tomorrow before dawn.
