Which of the following is used to identify target customers in marketing?

Market segmentation is a fundamental marketing strategy that involves dividing a target market into distinct groups of consumers who share similar characteristics, such as demographics, interests, or purchasing behavior. By identifying specific segments within the broader market, businesses can tailor their products, services, and marketing efforts to meet the unique needs and preferences of those groups.

This approach helps marketers focus their resources on the most promising customer segments, improving the effectiveness of their marketing campaigns and increasing potential sales. For instance, a company may segment the market based on age, income level, or lifestyle, and then design specific marketing messages that resonate with each segment.

The other options, while relevant to marketing, do not focus specifically on identifying target customers. Total revenue analysis looks at the overall income generated from sales and does not provide insights into customer segmentation. Sales tracking involves monitoring sales performance over time, which is useful for evaluating effectiveness but does not directly identify target customer groups. Advertising campaigns are the tactics deployed to reach customers but are typically formulated after identifying who those customers are through segmentation.
