Dashboards are essential tools for tracking and analyzing key performance indicators (KPIs), providing stakeholders with real-time insights into business performance for better decision-making. They can be categorized into strategic, tactical, and analytical types based on user needs, and must be designed with specific business goals and relevant data in mind. Implementing effective dashboards involves a structured approach, including stakeholder mapping, goal-setting, data connection, testing, and ongoing optimization to deliver actionable insights across various marketing channels.
