How to track your competitors’ prices on Amazon
Updated November 13, 2026
To track your competitors’ prices on Amazon, pick the three to five listings a buyer would choose instead of yours, watch their lowest price and the Buy Box price, and check them on a fixed schedule. You can do it by hand, in a spreadsheet, with Seller Central and Keepa, or with a tool that emails you a weekly summary. This guide compares the options and ends with a 10-minute weekly routine.
Why competitor prices matter
A competitor’s price cut can quietly move sales away from you, and you often only notice when your orders drop.
- The Buy Box. Most shoppers click Add to Cart on the featured offer and never compare sellers. Price, including shipping, is one of the biggest factors in who gets that box.
- Your price floor. The lowest price among the competitors you track, counting only new, in-stock offers, sets what buyers expect to pay. If you sit 15% above it, you need a reason a buyer will accept.
- Rank follows price. When a close competitor drops its price, its Best Sellers Rank often improves within days, and yours can slip.
You don’t need to react to every move. You need to see the moves early enough to decide calmly.
What to track
Six numbers tell you almost everything. Check them for each competitor listing you follow.
| What to track | What it tells you |
|---|---|
| Price floor | The lowest price among your competitors that are new and in stock: the price buyers compare you to |
| Your gap to the floor | How far above or below the floor you sit, in % |
| Buy Box price | The price the featured offer is selling at right now, and whether it is yours |
| Stock | A competitor that runs out leaves room for you to hold or raise your price |
| Best Sellers Rank | Whether a price change is actually moving sales, theirs or yours |
| Reviews | A jump in new reviews often means a competitor's sales picked up |
Watch the direction each week, not single readings. One low price for a day is noise; three weeks of drops is a trend.
Four ways to track competitor prices
The right way depends on how many products you sell and how much time you have each week.
| Way | Cost | Time each week | Best for | Where it falls short |
|---|---|---|---|---|
| Check listings by hand | Free | About 2 minutes per competitor | A few products | Easy to skip; no history unless you write it down |
| A spreadsheet you update | Free | 30–60 minutes for 10 products | Sellers who like their own numbers | Manual typing; goes stale the week you are busy |
| Seller Central and Keepa | Free, or about €29/month for Keepa's paid plan | 15–30 minutes of looking at charts | Detailed research on one product at a time | Lots of data to read; you still have to work out what changed |
| A weekly summary tool such as Pithies | From $29.99/month after a 14-day free trial | About 5 minutes to read one email | Busy sellers with 10 to 100 products | Not a repricer: it reports changes, you decide what to do |
Seller Central already shows part of the picture. In Manage All Inventory you can see whether you hold the featured offer, and the Pricing Health page lists offers that can’t win it right now (Amazon). It does not show a history of what each competitor did this week.
Keepa’s free browser extension adds price history charts to Amazon product pages and can alert you when a price drops below a target. Buy Box, rank and offer-count history need its paid plan (RevenueGeeks, Aug 2026).
Pithies checks your competitors’ prices three times a day and turns them into one plain-English email every Friday, plus an alert when a competitor cuts its price. You pick up to five competitors per product.
Picking the right competitors
Tracking the wrong listings gives you a price floor that means nothing. For each of your products, pick three to five listings that pass these tests:
- A buyer would really choose it instead of yours. The same model, or a very close one, at a similar size or pack count.
- It is sold new. Renewed and used offers sit at lower prices for a reason; leave them out of your floor.
- It is in stock most of the time. A listing that is always out of stock never sets the price.
- For private-label products, pick the two or three brands a shopper sees next to yours in search, not every similar item.
Revisit the list every month or two. Listings change, sellers leave, and new ones appear.
A 10-minute weekly routine
Pick the same day each week. Friday works well: you see the whole week and can adjust before the weekend.
- Check the price floor for each product and note whether it moved up, down or stayed the same.
- Compare your price to the floor. Flag any product more than about 10% above it.
- Look at who holds the Buy Box and at what price.
- Note stock-outs. A competitor out of stock is a chance to hold your price.
- Check rank changes to see whether last week’s price moves changed anything.
- Decide on two or three actions at most, such as matching a price, holding, or waiting a week. Then stop.
The routine works best when the numbers come to you ready to read, so the 10 minutes go on deciding, not collecting.
Common questions
- How often should I check competitor prices?
- Once a week is enough for most sellers, with an alert in between for big drops. Checking daily usually leads to chasing noise.
- Should I always match the lowest price?
- No. Matching every cut starts a race to the bottom. Match when the competitor is a true like-for-like offer and you are losing sales; otherwise hold and watch for a week.
- Is a weekly summary the same as a repricer?
- No. A repricer changes your prices automatically by rules. A weekly summary tells you what changed so you can decide. Some sellers use both.
