Keepa Amazon Price Tracker — Complete Setup & Strategy Guide
How to install and use Keepa to track Amazon UK price history, set price drop alerts, read price charts, and decide whether Keepa Premium is worth it.
Keepa Amazon Price Tracker Guide 📈
Keepa shows you whether any Amazon price is genuinely good — or just looks that way.
Keepa is a browser extension and web tool that embeds Amazon price history charts directly into product pages. It tracks prices across millions of Amazon products globally and alerts you when prices hit your target.
Why Keepa Is Essential for Amazon Shopping
Without Keepa, you see today's price but not whether it's the best price, the worst price, or somewhere in the middle. With Keepa, a glance tells you:
- Whether this price is at or near the all-time low
- Whether the price regularly drops (and by how much)
- Whether a "sale" price is genuine or just a temporary marketing price
- When to set an alert and wait vs. buy now
Amazon changes prices millions of times per day. The same product can be £80 today, £60 next week, and £95 the month after. Keepa maps every change so you can see the full picture.
Get Keepa for Chrome (free, also available for Firefox and Edge)
Installation (3 Minutes)
Step 1: Go to keepa.com or search "Keepa" in your browser's extension store.
Step 2: Click "Add to Chrome" (or your browser of choice).
Step 3: Once installed, navigate to any Amazon product page. Scroll down below the product description — you'll see a Keepa price history chart embedded in the page.
No account required for basic use. Create a free account if you want to set price alerts (required for alert functionality).
Reading the Price History Chart
The Keepa chart appears below the product images/description on every Amazon product page. Here's what each line means:
Green line = Amazon price (sold by Amazon.co.uk directly)
This is the most reliable price to track. If the green line is missing, Amazon itself doesn't stock this item — you're looking at third-party seller prices.
Orange line = New third-party seller price
The price from other sellers on the marketplace. Usually higher than Amazon's own price, but occasionally lower.
Blue line = Used / Warehouse Deals price (Keepa Premium only)
The price for used or returned condition items. Typically 15-40% below new.
Red/pink markers = Out of stock periods
When Amazon or sellers ran out of stock.
X axis = Time (you can zoom from 1 month to all-time)
Y axis = Price (£)
How to interpret at a glance:
| What you see | What it means |
|---|---|
| Current price is at or near the bottom of the chart | Good time to buy |
| Current price is near the top of the chart | Overpriced relative to history — wait |
| Price drops seasonally at a consistent time | Plan your purchase around that period |
| Single brief dip to a very low price | Likely an error or flash sale — not a reliable reference |
| Price has never gone lower than current | This may genuinely be a good deal |
Setting Price Alerts
You need a free Keepa account to set alerts.
Method 1 — Via the product page:
- Click the Keepa logo that appears on the Amazon product page chart
- Click "Track Product" or the bell icon
- Set your target price (the price at which you want to be notified)
- Choose notification method: email, browser notification, or Keepa app push notification
Method 2 — Via Keepa.com:
- Copy the Amazon product URL
- Paste it into the search box on keepa.com
- Click the bell icon and set your target price
Free tier alert limit: 150 active price alerts per month. For most shoppers, this is more than enough. Keepa Premium removes this limit.
Alert timing: Keepa checks prices continuously. Most users receive alerts within minutes of a price reaching the target.
Keepa Free vs. Premium — Is £19/Year Worth It?
| Feature | Free | Premium (£19/yr) |
|---|---|---|
| Price history charts | Yes | Yes |
| Price alerts | 150/month | Unlimited |
| Warehouse / used price tracking | No | Yes |
| Third-party seller price history | Basic | Full |
| Sales rank history | No | Yes |
| Product finder (deal search tool) | No | Yes |
| API access | No | Yes |
When free is enough: If you shop on Amazon occasionally (fewer than 15-20 times per month) and don't specifically hunt Warehouse Deals, the free tier covers all the core functionality.
When Premium is worth it: If you regularly buy from Warehouse Deals (the used price tracking pays for itself on the first major purchase), track more than 150 products simultaneously, or use Keepa for product research professionally.
Keepa Premium pricing — check the current annual price. It's often the same price as saving £20-30 on a single product you would have otherwise paid too much for.
Keepa's Product Finder — Hunting Deals Proactively
Keepa Premium includes a Product Finder that lets you search across Amazon by deal type, price history, and category. This turns Keepa from reactive (check specific products you already want) to proactive (find products where the price has dropped significantly recently).
Example search: "All TVs where the Amazon price has dropped more than 20% in the last 7 days."
This is how serious deal hunters identify opportunities they hadn't been specifically monitoring.
CamelCamelCamel vs. Keepa — Quick Comparison
| Feature | Keepa | CamelCamelCamel |
|---|---|---|
| In-page chart integration | Yes — embedded in Amazon | No — separate site |
| Free price alerts | Yes (150/month) | Yes (unlimited) |
| UK Amazon (amazon.co.uk) | Yes | Yes |
| Warehouse Deals tracking | Yes (Premium) | No |
| Mobile app | Yes | No |
| Cost | Free / £19/yr Premium | Free |
Recommendation: Install Keepa for its in-page chart integration (the biggest time-saver). Use CamelCamelCamel as a quick secondary check if you don't want to pay for Keepa Premium but want unlimited alerts.
The Keepa Workflow — For Any Amazon Purchase Over £30
- Navigate to the product on Amazon
- Scroll to the Keepa chart — is the current price near the historical low?
- If yes: buy now (or check Warehouse Deals first for a further saving)
- If no: set a Keepa alert at the historical low price and wait
- Before buying, also check if there's a sale event within 6 weeks that might drop it further
Time investment: 90 seconds per product. Worth it for any purchase over £30.
Mobile — Keepa App
The Keepa mobile app (iOS and Android) allows you to:
- Scan product barcodes in physical shops and check the Amazon price history instantly
- Manage your price alerts
- Receive push notifications when alerts trigger
This is particularly useful for in-store electronics and home goods shopping — scan the product, check whether Amazon is cheaper and whether the Amazon price is near its low. If it is, order from Amazon while standing in the shop.
