It’s not just low prices to get you to the top spot on Amazon and eBay. Being the most cost-effective option is an important factor, but there are many other aspects you’ll need to optimize in order to make sure you rank high and stay in that position. eBay has a system called “best match” which ranks listings based on the seller’s performance, recent search impressions and sell-through rate, recent sales, titles of listings, prices and whether or not free shipping is offered. Other important factors include TRS (Top Rated Seller) status and whether you offer Premium Service. It’s important to remember that most listings that reach the top page of an eBay search will be from Top Rated Sellers and will usually offer free shipping. These sellers will also have a large sales history and will offer the best price for that item. Amazon uses a similar system where it looks at seller rating and price, but it also looks at keywords in the product’s title to rank listings. The more keywords related to the search query, the more likely you are to rank highly.
