The report sounds awesome. I’ve been thinking about doing all my affiliate marketing via Amazon, because they offer amazing products and because they offer commissions on everything that “my” customers are buying. On the other hand, I’ve been thinking about focusing on a few products that I’m currently using. What I’m trying to say is that affiliate marketing is hard, and that finding the right products is actually harder than promoting them.
From what I’ve observed, most of the “programs” you’ve listed are networks, and most of them support dozens, hundreds, even thousands of merchants – in a huge variety of niches. Amazon is not technically a network, unless you factor in the presence of about a dozen entities like Zappos, Woot, Endless and the like. With very few exceptions, networks are diversified. Performance-Based.com focuses on eco and green merchants. Some support a particular locale – European merchants, for example.
Know when (and when not) to use Viglinks and Skimlinks. If you applied to an affiliate program but were denied, you might be able to still be an affiliate for that advertiser through a secondary affiliate program like VigLink or Skimlinks. Basically, they themselves are affiliates and will split their affiliate commission with you if you put their affiliate link in your content for an advertiser. Obviously, the commission rate is lower for you in this case, so if you ever are accepted into the advertiser’s affiliate program directly, immediately switch from using VigLink / Skimlinks affiliate links to your own.
