I'm thinking of building a site that helps affiliates discover programs that are a good fit for their audience. There are large lists of programs on affiliate networks (like impact, clickbank, etc), but there are many more programs that operate direct-to-affiliate (and hence, never make it on these lists) – so I think there may be some opportunity here.
If there are any successful affiliate marketers on here, do you even bother "searching" for affiliate products to promote? Or do you only choose to advertise products you already know, use and love.
If a discovery platform would be helpful to you, what's the hardest part about finding affiliate products to promote?
