Imagine you love playing with a toy but sometimes it breaks easily or it's too difficult to put together. Now imagine someone fixes these issues so that the toy is easier to use and lasts longer. This is what product optimization is all about - making something better by fixing the problems and making it easier to use.
For companies, this means making their products better so that people are happier with them and more likely to buy them again or tell their friends about them. They might change the design, the materials used, or even the way the product is advertised. All of these changes are made to improve the product and make it more appealing to customers.
So, just like how your toy can be improved, companies can optimize their products to make them more enjoyable and useful. And when they do, people are more likely to buy them and keep them for a long time.
