Niche
A niche is the specific, focused segment of the market your shop serves, defined by a combination of product type, style, audience, and use case. Examples include "boho macramé wall hangings," "personalized pet memorial gifts," or "goth-style enamel pins."
Niching down helps your SEO because it concentrates your listings around a coherent set of keywords, which strengthens your shop's relevance signals and helps Etsy understand what you sell. It also reduces direct competition compared with broad, generic categories.
A well-defined niche tends to attract a loyal, targeted audience that converts better. eRank's keyword and competition research can help you validate whether a niche has enough demand and how crowded it is before you commit your catalog to it.
