What Are Keepa Charts?

Keepa is an Amazon price tracking tool that tracks product data on Amazon, displaying it in easy-to-read charts. These charts include information on price history, sales rank, Buy Box statistics, and much more. 

Keepa allows tracking price fluctuations of products, monitoring sales rank trends, and estimating how quickly a product sells. It also contains a lot of data about the product sales history, reviews and ratings, and other essential information helping sellers figure out if a product is worth reselling. Keepa charts are available for most products in the Amazon catalog.

By visualizing this data, Keppa helps Amazon sellers make smarter, more informed decisions when they select products for reselling. Charts assist in refining product research and maximizing profits through smart data usage.

What Are Keepa Charts Used For?

Keepa charts offer crucial insights into product data that help Amazon sellers in their product research. These charts display price history, sales rank, and other key metrics, allowing sellers to make data-driven decisions and stay competitive in the marketplace.

Price tracking

One of the most valuable features of Keepa is its ability to track historical price changes for any product. Keepa charts provide a detailed history of a product’s price changes over time. Sellers use this data to identify pricing trends, decide when to buy or restock inventory, and set competitive prices.

Key use cases

• Analyze price trends over time;
• Identify the best times to buy or restock inventory based on price drops;
• Set price alerts for when products reach a desired price point.

Sales Rank monitoring

Sales rank data shows how well a product is selling relative to others. By tracking fluctuations in sales rank, sellers can gauge demand, track how well a product is selling over time, and spot seasonal trends.

Key use cases

• Help sellers gauge product demand and popularity;
• Take decisions on which products to buy based on sales;
• Provide insights into product seasonality.

Buy Box tracking

The Buy Box is the featured offer on an Amazon product page, and winning it is key to boosting sales. Keepa charts help sellers monitor Buy Box price changes and adjust their strategies to increase the chances of winning it more often.

Key use cases

• Understanding Buy Box statistics;
• What pricing strategies competitors are using;
• Whether changes in price or fulfillment method (FBA vs. FBM) influence Buy Box performance.

Competitor analysis

Keepa charts track the number of competitors selling the same product. Sellers can use this information to gauge market saturation, identify pricing opportunities, and strategize on how to stand out from competitors.

Key use cases

• Identifying number of competitors offering the same product;
• Spotting opportunities when competitors run out of stock;
• Planning competitive pricing strategies.

Amazon stock monitoring

Keepa can show when Amazon itself runs out of stock on a product, giving third-party sellers a chance to raise prices and capture more sales. This allows sellers to capitalize on temporary gaps in Amazon’s availability.

Key use cases

• Determine which products are sold by Amazon directly;
• See when Amazon is stocking or selling out of a product;
• Increase prices strategically when Amazon runs out of stock.

FBA and FBM trends

Keepa provides insights into whether products are being fulfilled by Amazon (FBA) or by merchants (FBM). Sellers can use this data to estimate competition levels and decide which fulfillment method might be more profitable for their specific products.

Key use cases

• Which fulfillment method might be more profitable;
• How switching to FBA or FBM affects the Buy Box win rate and sales;
• Whether to adjust pricing depending on fulfillment trends.

What Are the Keepa Chart Elements?

Keepa chart shows product price history. The left-hand side of the chart shows the price levels. At the bottom, it indicates the dates. The right-hand side displays the sales rank figures.

To the right of the chart, you can see the menu that lets you customize your view. You can select to display only the Amazon chart, New or Used products, Sales Rank, or Buy Box. 

Additionally, you can set a period to view the data — day, week, month, 3 months, year, or all.

What Does Keepa Chart Show?

Keepa charts provide a wide range of data that helps Amazon sellers analyze product performance and sales history. Below you can find the key Keepa chart elements description and the explanation how to interpret them in your product research.

Amazon in stock

Keepa shows if the product is sold by Amazon, not as a marketplace, but as a seller, and how long Amazon sells it. The chart displays Amazon’s price offer. 

The orange shaded area shows Amazon is in stock. If you see the white area between orange slots, that means Amazon was out of stock during that time. 

Interpretation

If Amazon is in the listing as a seller, it’s tough to compete with them. The internet giant has the most favorable conditions from the suppliers and can afford to offer a lower price. Also, they are reluctant to give away Buy Box to 3rd-party sellers. 

For that reason, Amazon in the listing is a red flag for sellers who prefer to avoid competing with it. Products sold by Amazon are not suitable for inexperienced sellers as well.

New and Used Price

The ’New’ purple line shows the lowest product offer in the New condition from a 3rd-party seller at any given time (the figure indicates the offer price, not the product’s sale price).

The ’Used’ black line shows the lowest product offer in the Used condition from a 3rd-party seller. That is also the offer price, not the product’s sale price.

Interpretation

The lowest product price offer gives the picture of the minimum current price level, helps set a price, and better estimate potential profit. 

When you set your own price, remember that the lowest price doesn't mean the optimal one. If you significantly cut your price, that can hurt your profit margin. Usually, when creating the offer, FBA sellers consider other FBA sellers’ pricing, while FBM sellers look at FBM offers.

However, if you want to consider the lowest-priced offer as an FBA seller, you must remember that it may come from an FBM merchant and not include shipping fees. In such a case, shipping costs must be added on top of the price.

If you deal with product research, the Used parameter is optional.

Private label seller listing

From a Keepa chart, you can understand if a product is sold by a private label (PL) merchant. Private label is a trademarked item for which only one seller holds all rights. Amazon resellers can’t sell such products.

Interpretation

From a chart, you can see that a product is PL. The items with a single seller in the listing are usually PL, while products that are not PL usually have multiple sellers. In the example below, the product is sold by one merchant during 195 days, which means it’s a PL product.

Sales Rank 

The right-hand side of the chart displays the sales rank figures, and the green line shows rank history.

Interpretation

Sales Rank (BSR) helps estimate how well the product sells. Amazon doesn’t show how much the product sells. It shows how the product sells compared to other items in the category. 

However, the sales rank indirectly indicates sales levels. The lower the rank, the better the product sells. Because sales rank changes, you must analyze the average figure and the trend — upwards or downwards — to see if product sales increase or decrease.

Also, if, during specific time periods, a product's rank goes down to zero, that may indicate a seasonal product. Such products only sell within a particular season, not throughout the year (e.g., summer or winter shoes). 

Suppose the Keepa chart shows that the rank goes down to zero in the high season and after seasonal sales start to increase, that may indicate a seasonal product. When doing product research, online arbitrage sellers must remember that such products do not sell all year round.

Buy Box 

Keepa displays a Buy Box as a pink line. A pink diamond appears when it spots a change in the Buy Box. To see details, hover your mouse over a mark.

Interpretation

Around 80% of sales happen in the Buy Box. Therefore, it’s crucial to win the Buy Box. The number of sellers fighting for the Buy Box and how they share it indicates the level of competition. It helps estimate your potential sales and profit in a specific deal. Identifying if Amazon is in the Buy Box is also essential. That is because if Amazon is a seller, it’s challenging to compete.

Also, you must look into the Buy Box dynamics — it shouldn’t drop or fluctuate too much. If it does, that means you won’t be able to sell a product at a stable price, and you must consider the average Buy Box price. When the number of sellers grows, the Buy Box price can drop because the sellers engage in a price war. That means price dumping and low margins.

Adversely, when the sellers leave the listing, the Buy Box price can go up.

New Offer Count

New Offer Count, Review Count, and Ranking are shown in a separate chart at the bottom. New Offer Count figures are displayed on the left-hand side and indicate the number of offers on a listing. 

Interpretation

A New Offer Count means other sellers on the listing are trying to sell the same item. Increased competition can show that a product is popular and it’s worth selling. However, if more than 15 merchants sell the item, the competition may be too high. 

Review Count and Rating

Review Count and Rating figures are displayed on the right-hand side and indicate the number of product reviews and the average number of stars it earned.

Interpretation

A product with no or bad reviews will likely not sell or generate many returns. Therefore, focusing on products with more than 10 reviews and a rating of 4 stars and up is better.
