But why not create a boat load of adsense sites and even if those sites make $8 a month, that person is still coming out way ahead even with the costs of domain and hosting.
Maybe it is too much upkeep to have 1,000 sites but once you do some SEO on them, isn't this the definition of passive income? Although I understand adsense to be a major risk especially with those numbers as you can be shutdown overnight without any explanation. Besides that, are there any other drawbacks?
Educate me please.
