Which term best describes a group of potential buyers for a product or service?

The term that best describes a group of potential buyers for a product or service is "Market." In the context of retail and business, a market encompasses all individuals or entities that have a potential interest in purchasing a specific product or service. This includes diverse categories of buyers who share certain needs or characteristics related to the offerings available.

The concept of a market is broad and can encompass various segments. While "Target Audience" refers more specifically to the particular group marketers aim to reach with their product or campaign, "Customer Segment" also denotes a more specific subset of consumers within the larger market who share distinct attributes or behaviors. Similarly, “Buyer Group” might imply a more focused grouping related to purchasing behavior, maybe in a business-to-business context, and does not capture the entirety of potential buyers as effectively as "Market."

Using the term "Market" ensures clarity in understanding that it includes all potential buyers, making it the most encompassing and accurate term for referring to a group of potential buyers for a product or service.
