A logo is what defines a business in visual way. A brand’s identity is defined by a logo. Your brand persona, your brand philosophy, basically the whole package is defined and encompassed by a logo. For many companies, a logo is the only identifiable mark a potential customer may ever see. That is why a logo needs to be memorable, descriptive and easily recognizable.
The logo of McDonald’s is a prime example for that. Short, simple and yet having a global recognition. If you wish for a logo to be created for your own company, it must be kept in mind that the logo be kept different and unique.
