The main optimizations that should be made is to involve adding your keyword targets into the product title, bullet points, and description section of the listing. You also want to make sure that you’ve filled out every field for the listing, and taken full advantage of the character limits to incorporate your keywords in a way that appeases Amazon’s algorithms, but also makes sense contextually for potential customers. Helium 10’s Listing Builder also enables you to include additional keywords in the “Subject Matter” section on the back-end of your listing (not visible to customers), which no other listing service is able to do.
