Should You Market Towards Everyone?

Is it a good idea to market to everyone or just try to reach a certain group of people? Apparently, when you market to everyone, you appeal to no one. Due to research, when you try to appeal to everyone you will make yourself spend more money, give confusing information to the people you are trying to reach, and is ineffective in every way because it would not have much cost value. Your product has to be specifically made for a specific group of people that way not everyone feels like they have reason to buy it; this makes it original because fewer people have the same piece of merchandise. Another reason, is if you make everyone think they can afford it then no one will spend big bucks on the merchandise or go out of their way to purchase it. Having a defined market is the best way to make an income.You have to have a target audience for when you advertise. This way you are trying to speak to a select group of people. Researching and gathering likes and dislikes of the specific group of people you are trying to reach is something you will have to do before you advertise. This way you can draw them in. Marketing towards everyone would be some very bland and boring tv commercials, radio ads, & social media pages.
