Merchant looking for creative ways to research what products to sell to affiliates
There are products that I can have private labeled and that I already have some experience with years ago and now I want to start up again but by market online through potential affiliates that desire the products to offer. Other than going to Clickbank or Share-A-Sale and looking for the top selling products, are there any other software or utilities that would give additional indicators (again from a merchants point of view) of which niche products that have room for more competition ? Other than looking at the top selling products, what other sources for data (or tricks for using the most popular data) can I analyze so that I know in advance what will draw a good audience of affiliates ?
The only thing that comes to mind is seeing the volume of sales compared to the number of suppliers of that type of product along with identifying which ones allow a very attractive commission. What other indicators I can look at ? What web sites or tools for merchants exist to give me data like this ?
