Competitor Tracker & Notifications

📋 Overview

The Competitor Tracker lets you track any ASIN - usually a competitor's - and set your own thresholds on it. Point it at a product you do not sell and it tells you when the Buy Box changes hands, when the price moves, when the rank shifts, when stock runs low, when the listing changes, or when the rating drops.

Watching your own catalogue? Use Offer Watch instead. Offer Watch covers every ASIN you sell automatically - new sellers, Buy Box changes, price undercuts, and suppressed listings - with no setup per ASIN. The Competitor Tracker is for the ASINs you do not sell. The page itself says so in a strip at the top, with an Open Offer Watch button (or Join the waitlist while Offer Watch is in early access).

This page also covers two things that are not trackers: the email notifications you can opt into under Settings → Notifications, and the Notification Center bell in the top bar.

🔍 Where to find it

Competitor Tracker is in the sidebar with a bell icon, at the bottom of the Amazon tools group, just below Fee Audit. Its URL is still /alerts.

📋 Page anatomy

Activity chart and stat cards

The top-left card is a Competitor Tracker activity chart with an "{n} total" tag. Beside it, three stat cards give a quick status - click any of them to filter the table below:

Card	Description
Active	Trackers currently monitoring
Paused	Trackers that have been temporarily suspended
Triggered Today	Trackers that have fired today

Quick actions

Action	Description
Create Alarm	A dropdown of quick templates plus Custom Alert (opens the full wizard)
Start All	Reactivates every paused tracker
Pause All	Pauses every active tracker
Refresh	Reloads the table
Export	Downloads your trackers as CSV or Excel (see Exporting)

Priority Log

A side panel listing the most recent trigger events. Each row shows the tracker name, timestamp, status, and ASIN, and a Logs → link that opens that tracker's log modal. Rows have a read / unread state with an unread count badge, plus Mark all read and Refresh buttons. Empty state: "No priority logs found." / "Alerts that fire will show up here."

---

Tracker types

The wizard offers ten types. Each is built the same way: pick a type, enter the ASIN, set one or more trigger conditions.

Type	What it watches	Parameter(s)
Buy Box Owner	The Buy Box on the tracked ASIN changing hands - the single question a competitor tracker exists to answer	Buy Box Holder (changes)
Price Change	The Buy Box price, the lowest offer price, or a percentage price change	Buy Box Price, Lowest Offer Price, Price Change %
Bestseller Rank	Best Sellers Rank movement	Bestseller Rank
Seller Count	The number of sellers / offers on the listing	Number of Sellers
Stock Level	The tracked ASIN no longer purchasable in quantity - Amazon caps the add-to-cart dropdown at what is left once stock runs low	Units Purchasable
Listing Down	The listing becoming inactive, suppressed, or unavailable - a competitor's outage is your opening	Listing Status (Down)
Listing Change	The tracked ASIN's title or main image changing - a relaunch or repositioning, confirmed over two checks before you are told	Listing Content (changed)
Rating Drop	The average star rating falling	Average Rating
Negative Review	New reviews landing while the average rating falls	Negative Review (detected)
Seller Feedback	The seller's positive feedback percentage	Positive Feedback %

Two older types were retired. Hijacking and Buy Box (loss) can no longer be created - Offer Watch now covers new sellers and Buy Box won / lost / suppressed across your whole catalogue, and neither type made sense on an ASIN you do not sell (every foreign seller read as a hijacker, and the Buy Box always read as lost). Existing trackers of those types keep running, still appear in the table, and can be edited or paused - opening one shows "Offer Watch now covers this alert across your whole catalogue. You can still edit or pause this one, but not create another."

Seller Count and Offer Watch overlap. The Seller Count type card always carries a note that Offer Watch already reports this catalogue-wide on the ASINs you sell, and suggests pointing the tracker at a competitor instead. It is a standing reminder on the card, not a check against the ASIN you type in.

🚚 Late-Shipment Alert (FBM)

Separate from the trackers above, SellerMagnet offers an opt-in late-shipment alert for your FBM (Merchant Fulfilled) orders. It lives in Settings → Notifications, not in the wizard, and is configured with a single toggle.

What triggers it

Once enabled, SellerMagnet watches your FBM orders and notifies you when orders are still pending shipment past their handling window, flagged at the 12-hour and 24-hour marks. You're emailed and notified up to twice per day so a slipping order doesn't go unnoticed.

Why it matters

Late dispatch hurts your seller rating. Amazon's Late Dispatch Rate and On-Time Delivery Rate are account-health metrics, repeated late shipments can suppress your Buy Box eligibility or, in severe cases, put your selling account at risk. Catching a pending order at the 12-hour mark gives you time to ship before it counts against you.

How to enable it

1. Open Settings → Notifications.

2. Find "Get notified about late FBM shipments."

3. Flip the toggle on.

Opt-in and project-scoped. The toggle is off by default, you'll never get surprise emails. It applies to the current project, so enable it per project if you run several. A confirmation toast appears when you switch it on or off.

---

📧 Email Notifications (Settings → Notifications)

The late-shipment alert above is one of several email notifications you can opt into under Settings → Notifications. These are separate from the tracker wizard and from the bell, they are periodic reports and account emails sent to your inbox. Each is a simple on/off toggle.

Most are configured per connected Amazon account (so if you have several stores connected, each one has its own set of toggles). A couple are scoped differently, as noted below.

Email notification	What it sends	Scope
Weekly Overview	Weekly summary of your account activity	Per Amazon connection
Lost & Found Report	Reimbursable inventory discrepancies (lost, damaged, or fee errors)	Per Amazon connection
PPC Overview	Weekly summary of your Amazon Advertising performance (only delivered when an active Amazon Advertising connection exists)	Per Amazon connection
Out-of-Stock Report	Alerts when products in your inventory go out of stock	Per Amazon connection
New Seller Review	Notifies you when a new review is received on that marketplace	Per Amazon connection
Late FBM Shipments	Emails you up to 2× per day when FBM orders are pending past 12h / 24h (see Late-Shipment Alert above)	Per project
Promotional Emails	Exclusive offers, discounts, and product promotions from SellerMagnet	Per account

Inventory Alerts are configured per product. The Notifications settings panel links out to the Products page for inventory-level alerts (low-stock and out-of-stock thresholds), those live on each product rather than as a single account-wide email toggle.

Email opt-ins are independent of the bell. These toggles only control which emails land in your inbox. They do not change what appears in the Notification Center bell (see below) or which trackers you have configured in the wizard.

➕ Creating a tracker

Click Create Alarm and pick Custom Alert (or a quick template - see below). The modal is titled "Track a new ASIN" - "Set up monitoring on any ASIN, yours or a competitor's" - and walks through four steps: Type, Product, Conditions, Notify.

1

Type

Choose one of the ten types above. Each card carries a one-line description of what it watches.

2

Product

"Which ASIN do you want to track?" - pick the Marketplace and enter the ASIN (exactly 10 characters). It does not have to be one of yours; anything that is not a valid 10-character ASIN is rejected.

3

Conditions

Add one or more conditions in the form "Notify me when [parameter] [operator] [value]". The operators are drops below, rises above, equals exactly, and changes from; the parameters depend on the type (see the table above). Some types have a fixed trigger - Listing Down fires on Down, Listing Change on Changed, Negative Review on Detected, Buy Box Owner on Changed.

4

Notify

Delivery is by Email (pre-selected) - every trigger also lands in the Notification Center bell. An Alert Summary on this step recaps the type, ASIN, and conditions before you create the tracker.

Delivery and frequency. Trackers notify you by email and in the bell. There is no webhook, SMS, or Slack channel on this page (the only webhooks in the product are the PPC Slack / Teams webhooks under PPC Settings). Checks run on a fixed schedule set by SellerMagnet - there is no per-tracker interval to configure.

Quick templates

Create Alarm offers ready-made starting points:

Template	Type	What it does
Buy Box Owner Alert	Buy Box Owner	Know when it changes hands
Stock Level Alert	Stock Level	Catch a rival running dry
Ranking Alert	Bestseller Rank	Monitor bestseller rank
Inventory Alert	-	Shortcut to the Products page, where low-stock and out-of-stock thresholds are set per product
Custom Alert	Any	Opens the full wizard

Empty state: "Nothing tracked yet" - "Add your first tracker to watch a competitor's ASIN for price, rank, stock and listing changes."

---

Logs modal

Click Logs on any tracker to see its history: Log ID, Status, Triggered, and Timestamp, paginated.

---

⬇️ Exporting (CSV and Excel)

The Export button is a split menu - pick CSV or Excel (.xlsx):

Column	Description
ASIN	The tracked ASIN
Alert Type	The tracker type
Status	The raw value: ACTIVE, PAUSED, or FAILED
Marketplace	The Amazon marketplace it watches

The export always contains every tracker on the account - the search box and the status chips do not narrow it.

Managing trackers

Editing

Click Edit in the Actions column, change the type, ASIN, or conditions, and save.

Pausing and starting

• Pause: the tracker stops monitoring but keeps its configuration.

• Start: monitoring resumes.

Use Pause All and Start All in the quick actions for bulk operations.

Sending a test notification

Click Send test notification in the Actions column to drop a sample into the Notification Center bell - "This is a test notification for your alert on ASIN {asin}. Delivery works - when this alert triggers you will be notified here." A toast confirms "Test notification sent - check the bell icon at the top right." The test exercises the bell only, not email.

Deleting

There is no per-row delete. Tick the checkbox on one or more rows and click Delete in the bulk toolbar, then confirm. The tracker and its log history are permanently removed.

🎯 Realistic Example

Scenario: You sell a premium desk lamp on Amazon.de. A rival brand launched a near-identical lamp last month and keeps winning searches you used to own.

Setup:

1. Buy Box Owner Alert on the rival's ASIN - notify when the Buy Box changes hands, so you know when a new seller (or Amazon Retail) has stepped in.

2. Price Change on the same ASIN - notify when the Buy Box price drops below your price point.

3. Stock Level on the same ASIN - notify when Units Purchasable drops below 5.

Day 9: An email arrives: the rival's Buy Box price dropped below your price. You open the tracker's Logs, confirm the drop, and adjust your own price in the Repricer.

Day 23: The Stock Level tracker fires - the rival can only sell 3 more units. You raise your ad budget on that keyword for the week and pick up the demand they cannot serve.

Without trackers you would have noticed the price cut days later, and the stockout not at all.

⚠️ Common Mistakes to Avoid

Mistake	Why It Hurts
Tracking your own ASINs here	Offer Watch already does that catalogue-wide, with no per-ASIN setup - use it instead
Setting rank thresholds too tight	You get flooded with noise from normal daily fluctuations
Ignoring triggered trackers	The tracker only works if you act on the notifications
Never opening the logs	The Logs modal is where you confirm what actually happened before reacting

✅ Best Practices

1. Point trackers at competitors, not your own products - your own catalogue belongs to Offer Watch.

2. Start with Buy Box Owner and Stock Level - they answer the two questions that move revenue fastest: who is winning, and who is about to run out.

3. Set rank thresholds at 15-20% to filter daily noise while still catching real trends.

4. Review the Priority Log daily - two minutes each morning, and mark it read.

5. Combine with the Repricer - when a competitor's price drops, your repricing strategy should already be responding.

❓ FAQ

Can I track my own products here?

You can, but you should not need to. Offer Watch monitors every ASIN you sell automatically - new sellers, Buy Box changes, undercuts, suppressions. The Competitor Tracker is designed for the ASINs you do not sell.

What happened to the Hijacking and Buy Box alert types?

They were retired because Offer Watch now covers new sellers and Buy Box changes across your whole catalogue. Trackers you already created of those types keep running and can be edited or paused, but new ones cannot be created. For a competitor's Buy Box, use Buy Box Owner.

Can I receive alerts via webhook, SMS, or Slack?

No. Trackers are delivered by email and in the Notification Center bell. There is no webhook channel on this page. (The product's only webhooks are the PPC Slack / Teams webhooks under PPC Settings.)

How often are tracked ASINs checked?

On a fixed schedule set by SellerMagnet. There is no per-tracker interval to configure, and check frequency does not depend on your plan.

Is there a limit to how many trackers I can create?

Limits depend on your subscription plan. Check your plan details for the maximum number of active trackers.

How far back do logs go?

The Logs modal shows that tracker's recorded history, newest first and paginated. SellerMagnet does not publish a fixed retention window for tracker logs, so copy out anything you need to keep permanently.

🔔 The Notification Center (Bell)

Separate from the Competitor Tracker described above, every dashboard page has a bell icon in the top bar that opens the Notification Center, a slide-out panel listing recent activity from across SellerMagnet.

Notification Center vs. Competitor Tracker, what's the difference? The Competitor Tracker (this page) is something you configure: you create trackers that watch specific ASINs. The Notification Center is a passive inbox that collects events SellerMagnet generates for you across the whole product, no setup required. Some of those events come from your trackers; many come from other features (inventory, sales, reviews, PPC, system messages).

Notifications, Changelog and Help

The bell cluster in the top bar gives you three top-level surfaces:

Tab	What it shows
Notifications	The Notification Center inbox described here (the bell icon)
Changelog	The latest SellerMagnet product updates and release notes
Help	Page-specific help and links into the Help Center

Changelog and Help open in a companion drawer alongside the bell, so you can jump between what happened, what is new, and how to use a page without leaving the dashboard.

Category tabs

Within the Notifications view, the panel groups notifications into tabs so you can focus on one area at a time:

Tab	Covers
All	Every notification, newest first
Tools	Product/system messages and tool events
Orders	Order- and sales-related notifications
Products	Stock and product notifications
Review Request	Review-request and feedback notifications
PPC Manager	Advertising notifications

Working with notifications

• Scroll to load more. The list loads additional notifications automatically as you scroll to the bottom, so older items are always within reach.

• Mark all as read. A Mark all as read control at the top clears the unread state in one click.

• Open for detail. Clicking a notification opens a detail view inside the panel; a back arrow returns you to the list.

The New FBM Refund card leads with what the return costs you. Its detail view shows the order and return status, then "Your cost so far" - only the part you carry, with each line attributed "you pay", "buyer pays", "Amazon pays", or "payer not stated" - then the return shipment (carrier, tracking, a Track parcel link) and the item with "{returned} of {ordered} returned". Reasons are written as sentences, and the A-to-Z flag reads "A-to-Z claim filed" or "No A-to-Z claim". If Amazon reported the refund as 0.00 because it has not settled yet, the card says so - the figure can still change.

Notification Preferences

A sliders icon in the panel header opens the Notification Preferences modal, where you can toggle individual notification types on or off. They are grouped into six sections: Inventory Alerts, Listing Changes, Sales & Orders, Repricer, Account & Performance Alerts, and Reviews. Turn off the types you don't want to see and click Save Preferences, or use Reset to Default to restore all of them. When one or more types are disabled, the panel shows a small reminder with a Manage shortcut back into this modal.

The full set of toggleable bell notification types:

Section	Notification type	Triggers when
Inventory Alerts	Out of Stock (FBA)	Your FBA inventory runs out
Inventory Alerts	Out of Stock (FBM)	Your FBM inventory runs out
Inventory Alerts	Low Inventory (FBA)	FBA stock is running low
Inventory Alerts	Low Inventory (FBM)	FBM stock is running low
Listing Changes	Listing Now Buyable	A listing becomes buyable again
Listing Changes	New Listing Detected	A new listing appears on your account
Listing Changes	Listing Deleted	A listing is deleted
Listing Changes	Listing Content Changed	Amazon serves different listing content than your last scan
Sales & Orders	New FBM Refund	A new FBM refund is detected
Sales & Orders	Amazon Fee Promotions	Amazon offers you a fee discount
Repricer	Repricer Status Updates	Repricer activity or status changes (e.g. a SKU is paused)
Repricer	Buy Box Lost Alerts	The Repricer detects you have lost the Buy Box
Account & Performance Alerts	Low On-Time Delivery Rate	Your On-Time Delivery Rate (OTDR) drops
Account & Performance Alerts	High Order Defect Rate	Your Order Defect Rate (ODR) is high
Account & Performance Alerts	Account Status Alerts	An important seller-account status change occurs
Reviews	Review Request Automation	Review-request automation runs or updates
Reviews	New Reviews	A new product review is received on any marketplace

These preferences only affect the bell. Toggling a notification type off in the Notification Center's preferences hides it from the bell panel. It does not change which trackers you've configured or whether they send email, those are managed in the trackers table above and in Settings → Notifications.
