In analytics, "metrics" are like measuring sticks that help you understand and track how well something is doing. 

They're usually numbers or data that tell you about performance, like how many customers you have, how much money you're making, or how many people visit your website. These metrics are important because they let you make informed decisions and see if you're moving in the right direction. For example, if you're running a business, you might track metrics like sales, customer satisfaction, or website traffic to see how well you're doing and where you can improve.
