To rely almost entirely on the creator. Those affiliates are not out to promote your work. I advise caution.
within next few weeks I'll be launching a new website, which will feature a parent-oriented course on a specific topic related to school age children (with plans to expand the website with new courses every couple months). We put a lot of effort into professional presentation of materials (videos and printables) and the overall production quality of the website.
I'm looking to join an affiliate program as a merchant/advertiser to get some traction with the course. I did some extensive research and so far ShareASale looks best to me - acceptable entry costs, large base of affiliates, and good history.
My biggest concern is, with a niche product like mine, will I be able to find affiliates with enough targetted traffic to actually bring some sales? Do you think I might be better off setting up my own affiliate program with something like iDevAffiliate and try to contact affiliates/influencers directly?
I will appreciate any advice. I'm an experienced web developer, but I don't have much knowledge in the merchant side of affiliate promotion.
