Interlink your Products

Within your niche, make sure you provide a variety of products . On each of your eBay auction ads, supply a link and an image of a related product that customer may like to purchase in addition to the original product.

This not only increases your chance of additional sales, it also helps to establish your authority in that particular niche, especially if you have several products offered. For example, yor niche may be Dolphins. Products that can be interlinked with each other could be mugs, T-shirts, coasters, gift lines such as dolphin pendants etc etc. You get the idea.

So interlink your products if you want to make more money selling on eBay.
