Marketing segmentation refers to the process of dividing a larger market into smaller, distinct groups of consumers based on shared characteristics or behaviors. This allows businesses to tailor their marketing strategies and messages to specific segments, increasing the effectiveness and efficiency of their campaigns. By understanding the unique needs, preferences, and behaviors of each segment, companies can create targeted and personalized marketing efforts that resonate with their intended audience. This approach helps businesses to better understand and connect with their customers, ultimately leading to increased sales and customer satisfaction.
