A Customer Data Platform (CDP) is a software system that collects and organizes customer data from various sources. It creates a unified customer profile by integrating information from websites, social media, email campaigns, and more. This helps businesses understand their customers better and tailor their marketing efforts accordingly. CDPs enable companies to analyze customer behavior and preferences, leading to more personalized experiences. By providing a single view of each customer, businesses can improve their targeting and engagement strategies, ultimately enhancing customer satisfaction and loyalty.
