Once you start a paid subscription for your E-junkie account, product listings from your E-junkie Shop would also become listed in the general E-junkie Marketplace. Our site's built-in search function is handled by Google, so products new to the Marketplace would not appear in search results until the next time Google revisits our site, about every week or so. It's been over a week since you subscribed, so your product should start showing up in searches any day now.
BTW, note that none of the text in the body of your listing (e.g., "Turn your body into a muscle machine" etc.) would be searchable, because it's part of your product image -- i.e., it's just a picture of text, rather than actual text content.
Most sellers sell primarily from their own Web site, where they would paste the Cart or Buy Now button codes we provide in Seller Admin, and would paste their affiliate sign-up link code if they have an affiliate program. Some sellers even set up a dedicated page in their site for affiliate recruitment, providing instructions and tips, banner images, etc. for their affiliates to use.
Online marketing forums like Warrior Forum can be good places to discover and ask for general tips and suggestions on how to promote an affiliate program and find affiliates, even if they won't let you directly promote your own program there without paying an advertising fee.
