As Olga suggests, it's quite unusual to launch an affiliate program to promote a retailer without first testing using other channels.
Affiliate marketing can be very successful for retailers, but it's usually a very slow channel to grow, in part because many publishers "wait and see" whether you're really committed and can convert traffic into sales. Other strategies (especially PPC
Search), can be used to quickly gather meaningful data, some of which might be shared when recruiting publishers.
Even if your long-term marketing plan doesn't include a PPC
Search component, I've not found any other marketing strategy that can gather so much useful data so quickly, at similar cost. (Of course, a poorly-designed PPC
Search campaign can quickly huge amounts of money without generating any sales or meaningful data.)
I don't have much respect for ClickBank, and I don't recall ever hearing of "e-Junkie" before your post.
And my entire income right now comes from advertising fees from advertisers selling "information products" (both tangible books and ebooks), but my focus is on advertising for relevant
products with a proven track record of usefulness
niche audience. (I carry advertising from just one ClickBank advertiser, with very modest success. I don't carry advertising for the get-rich-quick crap that's much more commonly offered through ClickBank.)
By using less-reputable, less-respected affiliate networks, you're limiting the audience of high-quality publishers who will even consider your advertising opportunity.
