Tracking products & BSR history

The Tracker (under Monitoring) saves Amazon products you care about and records a daily snapshot of each one. Instead of a single point-in-time number, you build a history you can read for trends — a product whose BSR is slowly climbing or whose price is being cut by competitors tells a very different story than its numbers today.

Each snapshot captures the signals that move a buying or sourcing decision:

• Price — the current listing price, so you can see discounting and price wars over time
• BSR (Best Sellers Rank) — the demand proxy; lower is better, and the direction of travel matters more than the absolute number
• Reviews — total review count, which shows how fast a competitor is accumulating social proof
• Rating — the average star rating, so you catch a listing whose quality is slipping
• Estimated monthly sales — a modeled figure derived from BSR and category

1. Open Monitoring → Tracker.
2. Paste an ASIN (the 10-character Amazon product ID) or add a product directly from the Product Validator or Product Database using the “Save to Tracker” action.
3. Confirm the marketplace (US, AU, UK, DE, and others). If we find the listing on a different marketplace than the one you picked, we’ll ask you to confirm before saving so your tracker doesn’t mix data across regions.
4. Optionally assign it to a group and add notes or tags to keep your tracker organized.
5. Save. We take an initial snapshot immediately so your history charts have a starting point right away.

Open any tracked product to see its history charts. A few things to look for:

• BSR trend — a steadily falling BSR means rising demand; a rising BSR means demand is cooling. Watch the slope, not just today’s rank.
• Price trend — sustained price drops across a niche often signal a margin squeeze or new entrants competing on price.
• Review velocity — fast review growth on a competitor is a sign they’re winning the category; flat growth can be your opening.
• Rating drift — a falling rating is where the gaps (and your differentiation angle) hide.

Lumai AI narrates what the chart is showing — it reads the measured snapshots, it doesn’t invent numbers. Treat its read as a judgment to weigh against your own, not a guarantee.

Snapshots are taken daily and history depth depends on your plan:

• Free — 7 days of history
• Starter — 30 days
• Growth — 90 days
• Pro — 365 days

The number of products you can track at once is also set by your plan. When you hit the cap, remove a product you no longer follow or upgrade for more slots.

• Groups — bucket tracked products (for example by niche, launch stage, or supplier) to keep a large tracker readable. Deleting a group keeps the products; they just lose the group label.
• Notes & tags — jot context on each product so you remember why you’re watching it.
• CSV export — export your full tracker on Starter and above to work the data in a spreadsheet or share it.
