Key Concept
Seller Research
Learning from the experience of others is the meaty part of research: it demonstrates what currently works in the eBay marketplace and what doesn't.
Here's a rule of thumb on how to spend your time:
New sellers & non-specialized sellers:
research 75% on products and 25% on sellers.
Established power sellers who specialize in a few brands/products:
research 25% on products and 75% on sellers.

How to Use Seller Research
Would you like to know exactly how other sellers are doing? Do you want to know which products are successful?
Fortunately for us eBay sellers, eBay has recently authorized seller research! Seller research lets you see other sellers' sales results so you know what sells and how to improve your sales without trial and error. Make your major decisions, like buying inventory or forecasting income, wisely by looking at other sellers' sales performance.
Here's how to do it: Find an seller who specializes in selling a product that you are interested in using either eSeller Street market research or eBay's completed listings page. The best sellers to study are Power Sellers who specialize in a few types of products. Cut-and-paste their eBay ID into the eSeller Street research page and hit search. This is the seller profile you will receive:
- What they sell - Top selling listings and categories
- How they sell - Avg start price and listing format - store, fixed or auction
- Are they successful? - Avg sold price, success rate and total revenue
- How much work (listing and shipping) do they do? - Number of items listed and sold/shipped.
