Why do most Click Bank Marketers Fail. They are clueless about concept of niches. They spread themselves to thin. They use expensive traffic. They choose a manually intensive traffic source. They promote only one traffic source. They promote only one product in their niches. They pick a niche they have no personal interest in. They assume gravity of everything. They got on the Click Bank Bandwagon.
