so im interested in beginning affiliate marketing as a business and I've been doing research on youtube the last week and i keep coming across the same programs of click bank and amazon affiliates. I made a click bank account and went through the products but everything there seems eh not great. I assume that it works because everyone says to use it but why? are their other programs with more known brands ? are people getting commissions to promote click bank? idk im just curious
