I actually spent a year and a half working as an affiliate marketer (mostly selling drumming related products – lessons, kits ect). 5 years on and one of my one page sites (which I’ve not touched) still nets me about $150 a month. I won’t be retiring off that but only really now appreciate the reverse pyramid approach to entrepreneurship (working for nothing initially but later being paid without effort!)
This is perhaps one of the most talked about methods of earning a passive income. Essentially, you advertise for others through inserting a link in forums, through social media, and of course through your own site. There are several software packages available for purchase, including Google Adsense, Bing, and Yahoo. These types of ads can be used to attract consumers of a particular gender, age, and individual interests.
