From chapter: CHAPTER 4 Step Two: Determining Your Space, pp. 58–63
Using Willie Keeler's line about hitting them where they ain't, Schaefer argues that your interest also needs an uncontested space. First-mover advantage, as with wine blogger Jamie Goode, is real but vulnerable, and failing to find a meaningful space is the primary reason people fail. He gives a Google test for saturation: fewer than 500,000 results is very good, 500,000 to 1 million needs work, and more than 1 million means tweak your angle. Even crowded niches can be entered, as Hickok45's gun videos show, and the chapter lists eight strategies for doing it.
