Answer: The main disadvantage of mass marketing is that this method of marketing can be successful in one geographic area but may not resonate positively with consumers in other regions. When marketing your business products, it is very important to know that your product will not impress all consumers because consumers have varied needs and desires. In addition consumers can also get bored when they see the name of a particular product everywhere. It can actually make consumers to loss interests with your business products. If you integrate this form of marketing to your business, you may end up spending more money but getting less sales.
