Well, if you think you have a winning formula for a business, then you can be sure there are 10 others who think the same way! There are very few businesses in this world that function as a complete monopoly. As a business, you will want to differentiate yourself and the only way to do it is by creating a logo that they can associate with your business uniquely. For instance, if we consider the business of household repair, a common logo will have tools. But if you dig deeper into what values your business stands for you may be able to come up with something that tells people about your business without being common.
