How to Read a Keepa Chart in 60 Seconds (UK FBA Deal Check)

Quick answer: four checks, in order: sales rank drops (does it actually sell), Buy Box price stability (is the price real), Amazon's stock shading (are you competing with Amazon), and offer count trend (is it getting crowded). Sixty seconds on those four tells you more than an hour of staring at the listing.

Published September 2026. Keepa Premium was €29/month (€290/year) as of September 2026 - the free tier shows price history but hides the sales rank and offer data this guide needs.

Why the chart matters more than the listing

A listing shows you today: today's price, today's sellers, today's rank. None of that tells you whether today is normal. Keepa shows you the last 3-12 months, and deals live or die on what is normal, not what is on screen.

The classic trap: a product at £24 with a "best ever" rank, and your buy cost works beautifully. The chart then shows it sat at £17 for eight of the last twelve months. You did not find a deal; you found a spike.

The 60-second check, in order

1. Sales rank drops (0-15 seconds)

The sales rank line shows how often the item actually sells. Every sharp downward drop is roughly a sale or a cluster of sales. You want regular, frequent drops across the whole chart - not one busy week in December and silence since.

Good: steady drops every day or two for months. Bad: long flat sections with occasional falls. Flat means nobody is buying at any price.

2. Buy Box price stability (15-30 seconds)

Look at the new-price history, not today's number. Is the price you plan to sell at the price it actually sells at, month after month? Wide swings mean the market has not settled, and your margin calculation is a guess.

Good: a price that wobbles within a tight band. Bad: regular dives of 20-30% that recover slowly - each dive is someone tanking the price to clear stock, and you will hold through the next one.

3. Amazon's stock shading (30-45 seconds)

The orange shaded area marks when Amazon itself is in stock. Competing with Amazon on price is a game you rarely win - they can sit on the Buy Box at a price that loses you money.

Good: no orange, or orange that appears briefly and disappears. Bad: solid orange for most of the chart. Also watch the pattern: some products show Amazon dipping in and out every few weeks, tanking the price each time. Predictable, but painful.

4. Offer count trend (45-60 seconds)

A rising count of sellers over recent weeks means the deal is circulating in lead groups and Discords. Hundreds of people buying the same 20 leads is why prices tank after a "hot deal" spreads.

Good: stable or falling seller count. Bad: a count that has doubled in the last month - your margin has a countdown on it.

Two UK-specific notes

Prices on Amazon.co.uk charts include VAT. When you compare the chart price against your costs, strip the 20% first - a £24 selling price is £20 before VAT, and fees come out of that.

Rank is relative to category, not universal. Rank 50,000 in Home & Kitchen moves differently to rank 50,000 in Toys. Learn the rhythm of the two or three categories you actually sell in rather than memorising generic rank tables.

What 60 seconds cannot tell you

The chart says nothing about your costs, your eligibility to sell the brand, IP complaint history, or whether the product is hazmat or oversized. Keepa is the first filter, not the decision. Deals that pass the chart still need a proper margin calculation and an account-health check before you spend a pound.

Frequently asked questions

Is free Keepa enough for this check?

No. The free tier hides sales rank history and offer counts, which are checks 1 and 4. As of September 2026, Premium is €29 a month.

How far back should I look?

Three months minimum, twelve for anything seasonal. A product can look stable in August and be unsellable by October.

What rank is "good" for UK FBA?

There is no universal number - rank speed varies hugely by category. Watch the drops on the chart for products you already sell, and calibrate from your own sales first.

Does a price spike mean a good deal?

Usually the opposite. Spikes attract sellers, seller counts climb, and the price reverts. The stable, boring products are where steady margin lives.

Can I trust the Buy Box price when Amazon is in stock?

Treat it as Amazon's price, not yours. When Amazon sells, third-party sellers often get few or zero sales at the same price.
