KPIs mean key performance indicators, which are simple numbers that show how a business is doing. They help you see if your work is bringing results or not. For example, a shop can track sales, website visits, or how many people send messages. The right KPIs depend on your goal, not what others are using. If the goal is sales, focus on orders and revenue. If the goal is growth, focus on traffic and signups. Which KPIs do you think matter most for digital marketing?
