Marketplace listings · For K-beauty brands
See the listings you cannot see.
Plug Watch watches marketplace listings of your products on channels outside our daily price comparison. Today that means TikTok Shop and Amazon. For each listing we record what the page displayed and on what date: the product, the seller shown, the price seen, and the units sold where the channel shows them. We report it. We do not judge it. What it means, and what to do about it, is your call.
No pay-to-rank. We never take payment to hide a listing or move a ranking. How we check.
Why this is hard to do yourself
Marketplace pages change faster than a person can check them.
Your products appear on marketplace channels you did not plan for, and each listing shows its own seller name, its own price, and its own units sold. The price moves. One listing has shown us $80.00, $91.00, $92.00 and $95.00 at different moments, while its seller name and units sold stayed the same. So we record each page with the date we read it, and we tell you plainly what we checked. We see what the channel's own search returns to a visitor in the United States, and some pages cannot be read on a given day. That is real information, not a guarantee that nothing else exists.
What Plug Watch does
Listings on other channels
We watch marketplace channels outside our daily price comparison. Today that means TikTok Shop and Amazon. We add channels as we can read them well.
What the page showed
For each listing: the product, the seller name shown, the price seen, and the units sold shown. Nothing added, nothing guessed.
The date we saw it
Every line carries the date we read the page. Prices on these channels move, so a price is one moment — not the price shoppers see.
Your price floor, if you send it
Send us your minimum advertised price and we will flag anything listed below it. Until then we simply report the price the page showed.
Your seller list, if you send it
Send us the sellers you've authorized and we'll flag any listing from a seller who isn't on it — as a fact against your list, not a verdict. Until then we report the seller name and leave the judgment to you.
You decide what it means
We report. We do not judge. Whether a seller is authorized is your call, and any decision to act is yours and your counsel's.
How it works
- 1
Tell us your brand and your products. Send your minimum advertised price if you have one.
- 2
We check marketplace channels outside our daily price comparison and read what each listing displays.
- 3
You get the product, the seller name, the price seen, the units sold shown, and the date we saw it.
We report. You decide.
Plug Watch records what a listing page displayed and the date we read it. If you send us your authorized-seller list, we flag any listing from a seller who isn't on it — as a fact against your own list, never a verdict on the seller. We still never say a seller should not be selling your brand; that judgment is yours and your counsel's. We do not take payment to hide a listing or move a ranking. Send us your minimum advertised price and we will flag anything listed below it.
Common questions
What does Plug Watch actually do?
It watches marketplace listings of your products on channels outside our daily price comparison. Today that means TikTok Shop and Amazon. For each listing we record what the page displayed and on what date: the product, the seller shown (on Amazon, the seller currently holding the buy box), the price seen, and the units sold where the channel shows them.
Do you tell me if a seller is allowed to sell my brand?
Only against your own list. If you send us your authorized-seller list, we flag any listing from a seller who isn't on it — as an observed fact against the list you gave us, not a verdict. We still don't decide whether a seller is allowed to sell your brand; that call, and any action, is yours and your counsel's. Until you send a list, we simply report the seller name the page displayed.
Can I trust the price you report?
Treat it as one moment, not a market price. Prices on marketplace channels move. The same listing has shown us $80.00, $91.00, $92.00 and $95.00 at different times. Presence, seller name and units sold have been much more stable. Do not treat these numbers as the price shoppers see.
Do you see every listing of my brand?
No. We see what the channel's own search returns to a visitor in the United States, and some pages cannot be read on a given day. We tell you what we checked and when. It is not a guarantee that nothing else exists.
Can you flag prices that are too low?
Yes, if you tell us your floor. Send us your minimum advertised price and we will flag anything listed below it. Until you send it, we simply report the price the page showed.
Is this only for big brands?
No. It is built for Korean brands that are starting to appear in the US and do not have a person free to check marketplace pages by hand every week.
How much does it cost?
The Brand Hub tools are free for founding-partner pilots in our Ieum program right now, and founding partners lock in a founder rate when paid plans launch (from $125/month).
