6) Check the overview boxes to get a feel for how competitive the category is, an indication of how much is selling, and how many listings are included in the analysis.
  • Are there enough listings for the analysis to be meaningful or do you need to broaden your categories or keywords?
  • Does the volume of listings feel competitive or suggest an untapped niche?
Overview Boxes
7) Click the graph icon located on the top right of the data table – this is the best place to start.
The graph uses a bar chart to show the percent of listings in each price bracket. It uses a scatter plot (dots) to show the individual listing’s average weekly sales volume. If you hover over a bar or dot, metrics will appear.
If you can’t see the whole graph, click the Hide Headers button.

8) Use the filters on the left navigation to narrow the price range so that you can see price and sales relationships, and/or to narrow the product further.
  • Is there a price range where listing supply is low but there is evidence of buyers paying a higher price?
The graph below has been filtered on Price, using a maximum of $150, as well as Category (Sheets) and Condition (New).

9) The graph shows that most of the listings for queen sheets is in the $15 – $40 range with sellers achieving varying success.
It also shows that some sellers are achieving high sales in the $60 – $75 range where there is almost half the volume of listings. There is even a seller making relatively high sales around the $90 price point.
Premium members can click on the scatter plot to reveal the listing’s details:
  • Click on the dots that are selling higher volumes to see what’s different about the listings. Are they for a certain brand, have a particular product feature, using the appearance and content of their listing in an appealing way, or using specific keywords?
10) Explore further by looking at the data table. It defaults to the Sellers tab.
  • Sort by $sold/wk to see the sellers that are achieving the greatest sales revenue, the number of listings driving that revenue and their average prices.
Premium members can click the Seller name to show the individual listings.
  • Do the top ranking sellers offer products across a range of prices?
  • Do they offer branded, their own brands, or non-branded items?
  • Are only some of their listings driving sales and, if so, what’s different about them?

In order to provide meaningful data this report uses a subset of eBay’s total data.
First we only take eBay’s top ranking listings. This helps to ensure results aren’t skewed by scam listings, Bob’s home spring clean or Jane’s listing that she put up when she first joined eBay and promptly forgot about.
Next we include only the listings that were created in the last 18 months – this time period enables enough data points for the analysis to be useful whilst also allowing results to be relevant. On the rare occasion there may be a listing that was posted prior to the 18 month period that is achieving recent sales that won’t appear in this report. If it’s a listing worth your attention it will appear in the Top 500 report.
Then we remove listings where the quantity is one as they, by their very nature, cannot show sales volumes greater than 1 for any price point.
Lastly, auctions are excluded as they tend to behave very differently to listings with a set price.
What remains is a very clean set of comparable listings.
