What Is Listing Hijacking (and Why "Instant" Doesn't Mean "24/7")
A hijacker, diverter, or unauthorized reseller appearing on your Amazon listing can sit there undetected for weeks — quietly eroding your Buy Box control, undercutting your price, or selling something that isn't even your genuine product. By the time most brand owners notice, real damage is already done.
An Important Honest Note Before You Install This
"Instant" here means the check happens the moment you look — not that this extension is silently watching Amazon around the clock in the background. Genuinely 24/7 monitoring would require either a paid backend service running independently of your browser, or a background process automatically fetching Amazon pages on a timer even while you're not browsing — the second of which sits much closer to automated bot scraping than anything else this tool does, and isn't something we're willing to build into a Chrome extension.
Key Brand Owner Pain Points and How This Extension Solves Them
| Pain Point | How the Alert Solves It |
|---|---|
| A new seller appears and you don't notice for weeks | Instant detection and alert the moment you visit the page, not a delayed manual check |
| You have to remember which ASINs you're watching and check each one manually | A running alert inbox shows everything detected across all your tracked ASINs in one place |
| You forget which alerts you've already looked into | Unread/reviewed tracking keeps a clear record of what still needs action |
| You want to know immediately, not just when you happen to open the extension | A native Chrome notification fires the instant a new seller is detected |
How the New-Seller Alert Works
Step 1 — Visit Your ASIN's Product Page
The first time you visit any product page, the extension quietly records who's currently selling it — nothing is flagged yet, since there's nothing to compare against.
Step 2 — Visit Again Later
On your next visit, the current seller list is compared against what was recorded last time. Anyone new triggers an instant alert — both a native Chrome notification and an on-page banner.
Step 3 — Review the Alert Inbox
Every alert lands in the popup's inbox, marked unread until you review it. Free tier tracks up to 10 ASINs; Pro is unlimited.
Worked Example — Catching a Diverter
Monday: You visit your best-selling ASIN's page as part of your regular routine. The extension silently notes the two sellers currently listed — this is the first time it's seen this ASIN, so nothing is flagged.
Thursday: You visit the same page again. A third seller, "QuickShip Direct," now appears alongside the original two. The extension instantly flags it — a Chrome notification fires and the popup inbox shows a new unread alert.
Result: You catch the new seller on your first visit after they appeared, not weeks later.
Where Brands Actually Use This
Building a Daily ASIN-Check Habit
Brand owners who check their top ASINs each morning get the most value here — the "instant" check happens automatically as part of a routine you're already doing.
Watching a New Product Launch Closely
In the weeks right after launching a new ASIN, hijackers and diverters often move fast — visiting the page regularly during this window catches problems earliest.
A Note on Accuracy
Detection reads only the publicly visible seller list on a page you're already viewing — never a live authenticated session or an automated background fetch. If Amazon's page layout doesn't match the tool's detection patterns on a given page, it simply finds nothing rather than falsely reporting "no new sellers." All data stays local to your browser except an optional license check for Pro features.
Common Mistakes (and How to Avoid Them)
Fix: This checks on visit, not in the background — build a habit of checking your key ASINs regularly for the "instant" part to actually matter.
Fix: This flags anyone new, regardless of authorization status — pair it with the Authorized Reseller Cross-Reference Watcher to check against your actual approved list.
Frequently Asked Questions
Does this monitor my ASINs in the background, even when I'm not browsing?
No — it checks the moment you visit the page yourself. There's no background polling of Amazon at any interval.
Will my first visit to an ASIN show a false alert?
No. The first visit to any ASIN establishes the baseline silently — alerts only trigger from your next visit onward if something genuinely changed.
How many ASINs can I track?
Free tier tracks up to 10 ASINs. Pro unlocks unlimited ASIN tracking.
Does this connect to my Amazon Seller Central account?
No. It only reads the publicly visible seller list on a product page you're manually viewing.
