By seeking out smaller segments of larger markets, referred to as niches, a website can be developed and promoted quickly to uniquely serve a targeted and usually loyal customer base, giving the affiliate a small but regular income stream. This technique is then repeated across several other niche websites until a desired income level is achieved.
