Affiliates need to know which items to focus their time on and they need to know which items are selling and which items are not selling. Affiliates should be able to see the product title (not the SKU) so they know which items sell the best. Otherwise they are in the dark. If you were an affiliate and you were promoting 100 items, you would want to know which ones are your top sellers and then focus on the top sellers. Why waste your time promoting items that aren't selling. Each vendor has their own SKU's and some are just numbers and many SKUs would not make sense to the affiliate as it is an internal number/code so that is why I think the product title is crucial to show the affiliate but NOT the sku.
Show affiliates the product title of what sold
