Customers are individuals or groups who purchase goods or services from a business. They play a crucial role in the economy, as their choices and preferences drive demand. Businesses strive to understand their customers' needs to provide better products and services, ensuring satisfaction and loyalty. Understanding customers' behavior helps companies tailor their marketing strategies. For instance, by analyzing data from surveys or social media, businesses can identify trends and adjust their offerings. Happy customers often become repeat buyers and may even recommend the business to others, creating a cycle of growth and success for the company.
