Knowing your customer means understanding who they are, what they like, and what they need. It's like making a new friend - you want to learn about them so you can be a better friend to them.
In business, we need to know our customers so we can sell them things they like and want. This helps us make money and keeps our customers happy.
To know our customers, we might ask them questions, look at what they buy, or watch what they do. This helps us figure out what they might want or need in the future.
It's important to do this because if we don't know our customers, we might sell them something they don't like or need, and they will be unhappy. We might also miss out on new products or services we could offer them.
So, knowing your customer is like making a new friend and trying to understand them so you can help them better in the future.
