Imagine you're in a big store with lots of cool toys and fun things to play with. Retail marketing is like the grown-up version of making that store really fun and exciting so that people want to come and play with everything in it.
The people who make the store fun are called marketing experts. They create cool displays with bright colors and fun signs that catch your eye. They arrange things in a way that makes it easy for you to find what you're looking for and discover things you didn't even know you wanted.
They also make ads on TV, online, and in magazines that tell you about all the cool stuff in the store. They might even send you coupons or special deals to encourage you to come and buy things.
When you go to a store, you're not just looking for stuff to buy. You're also looking for a fun and exciting experience. Retail marketing is all about making that experience as awesome as possible so that you want to come back again and again.
