Hi, Lynda. What you were talking about at the end sounded more like a pyramid scam. That is MLM being described and not affiliate marketing. Pressuring friends and family is not the method of affiliate programs in my experience. I once was an affiliate for Godaddy and did that for making extra money on a great hosting service that I used as a consumer. I used organic SEO to attract people and put a link in my email signature at the time.
There are many very high-quality services and/or products that offer affiliate programs. You can search for affiliate programs both in Nigeria & internationally. Affiliate marketing works.
