The bad news finds you before the sales dip does.
A hijacker takes your Buy Box. A competitor cuts price 15%. Your listing disappears without notice. The Product Monitor checks your ASINs and your competitors' every week (daily on the first ASINs you added, from the Brand plan) and puts every change in one alert feed. No account connection required.
Included in every OptimalCentral plan — part of a 30-tool suite, one subscription, from $99/mo. Account-connected checks from the Brand plan.
Every change, before and after. Zero surprises.
Every check stores a snapshot. Every alert shows what changed, from what, to what.
Buy Box & hijacker watch
The Buy Box seller on your ASIN changes or disappears (the classic hijacker signature), and you see who took it.
Price & BSR movement
Price moves of 5%+ and Best Sellers Rank drops of 30%+ on any monitored ASIN (default thresholds, adjustable per ASIN). A competitor's price cut arrives as an alert.
Rating & review slides
Rating drops, with the count of new ratings behind them. Plus an alert when reviews arrive faster than the ASIN's usual pace, so you catch a review wave early.
Suppression & stock-outs
A listing that stops returning data (a common sign of suppression) or a Buy Box showing out of stock is flagged on the next check. A listing that comes back gets an all-clear.
On a connected account, the monitor reads what only Amazon knows.
The checks above work on any ASIN with no connection. On the Brand plan (and your 14-day trial), connect your Amazon account and the monitor adds four account-level checks, read daily. Every alert is a change; the first read after you connect sets the baseline.
Suppression reasons, straight from Amazon
Your suppressed listings, each with Amazon's reason and fix instructions, and an alert the day a listing is suppressed, deactivated or reinstated.
Account Health, Amazon's own scorecard
Account status, Account Health Rating, every performance metric against Amazon's target, and your policy record. We add no score or threshold of our own. You hear when a metric crosses Amazon's target, a policy defect appears or a status changes, and again when it recovers. Seller accounts, read-only.
A+ content coverage
Which ASINs have no published A+ content, which A+ documents are built but not live, and the standard modules published (documents with premium modules can't be read back through Amazon's API). Alerts when published A+ disappears from an ASIN or a document's status changes. Seller and vendor accounts, read-only: it never creates, edits or submits A+ content.
Minimum advertised price
Set the lowest price you want an ASIN advertised at. Every morning we read its competing offers and record any below that price: seller, item price, first and last seen, downloadable as CSV. You get an alert when an offer newly drops below it, not every day it stays there. We report what is on the page; what you do is your call.
Add ASINs once. Read the feed weekly.
Add ASINs
Yours and your competitors', up to 10 at a time. Each gets an immediate first check that becomes its baseline snapshot.
Fresh snapshots
Each ASIN is re-checked every week, and the first ASINs you added also daily at 6 AM ET: 10 on Brand, 25 on Enterprise, which adds a second 6 PM ET pass on the first 5. Price, BSR, rating, Buy Box seller, availability, and title are diffed against the last snapshot.
Act on alerts
Every change lands in the alert feed with before/after values. Reprice, report the hijacker, fix the listing, or act in a competitor's stock-out window.
Frequently asked questions.
What does the Product Monitor watch?
Nine signals per ASIN: price moves of 5%+, Best Sellers Rank worse by 30%+, rating drops of 0.1+ (with the count of new ratings), a surge in new reviews against the usual pace, Buy Box seller change or loss, out of stock, title changes, Amazon's "bought in past month" figure moving by 1,000+, and the listing going unavailable (a common sign of suppression) or coming back. Price, BSR and rating thresholds are defaults you can adjust per ASIN.
How often are products checked?
Once when added, then weekly. On Brand, the first 10 ASINs you added are also checked daily at 6 AM ET; Enterprise covers the first 25 daily and adds a second 6 PM ET check on the first 5. The rest stay weekly. Each check stores a snapshot (price, BSR, rating, Buy Box seller, availability, "bought in past month"). Alerts show what changed between snapshots, from what, to what.
Should I monitor my own products or competitors?
Both. On your ASINs it catches silent revenue losses: a hijacker taking the Buy Box, a rating slide, a suppressed listing. On competitors it catches price moves and stock-outs, often your best moments to push.
Does it detect listing suppression?
Yes, two ways. With no connection, a listing that stops returning data is flagged (a common sign of suppression). With your Seller account connected on the Brand plan, the monitor also reads Amazon's suppressed-listings list daily, with Amazon's reason and fix per entry, and alerts the day a listing is suppressed, deactivated, or reinstated. Search rank is a separate signal: the Rank Tracker measures organic page-1 position.
Do I need to connect my Amazon account?
Not for the core monitor. Price, BSR, Buy Box, rating, stock and suppression checks run on any ASIN with no connection. Account-level checks (Amazon's own suppression reasons, Account Health, A+ coverage, MAP prices) need a connected account and the Brand plan, included in your 14-day trial.
Can it watch my Account Health, A+ content, and MAP pricing?
Yes, on a connected account from the Brand plan. All three are read-only. Account Health mirrors Amazon's scorecard and alerts when a metric crosses Amazon's target, a policy defect appears, or a status changes. A+ coverage lists ASINs with no published A+ and A+ documents built but not live, and alerts on changes. The MAP check reads competing offers every morning on each ASIN you set a minimum advertised price for, and records any below it.
How many ASINs can I monitor?
Plans include 25 (Pro), 60 (Brand), or 200 (Enterprise) concurrently monitored ASINs, of which 10 on Brand and 25 on Enterprise also get daily checks. Deleting one frees the slot immediately. The free trial monitors up to 5 ASINs.
