Some businesses think their target market is a broad group of people such as “working professionals.” While all working professionals may benefit from your product, you need to narrow your market to a specific group of people so you can market your product more effectively.
If you don’t narrow your market, your message will be broad and unlikely to grab anyone’s attention. For example, if you’re selling a slow cooker and your audience is “everyone,” the most you can do is tell people about the features of the slow cooker and the convenience of cooking a meal without much effort. You might get some sales, but not many, because there’s no real motivation to buy.
