A niche is a tightly defined portion of a subcategory. For example, think of the health and beauty category. This is a very wide category. A beauty salon can offer a wide variety of services, including tanning, waxing, facials, massage, cellulite treatment and much more. If, for example, we take one of these subcategories—let’s say cellulite treatment—this could be our niche. However, we could tighten it up even further by focusing on cellulite treatment for women who’ve just had a baby. This is a tightly defined niche.
