I basically agree with this.
There are two basic ways to get going in this business, one takes money, the other takes time.
Both take work.
This is quite different from the other affiliate industries – the rewards are a lot better. But the competition is also stiff, and it is not so easy, you can’t just slap a site up and expect it to make money. You have to keep tweaking it, getting it into the search engines, and eventually you will probably want to buy traffic anyway. But wait on that until you have some money saved up and concentrate on the search engines first.
