A logo is a graphic mark, emblem, or symbol used to aid and promote the identification and recognition of your brand by consumers. It may be an abstract or figurative design or include the text of the name it represents as in a wordmark.
A good logo shows what a company does and what the brand values. Perhaps the most fundamental function of a logo is giving your business a unique mark that differentiates you from other businesses. Of course, you don’t want to be so unusual that potential customers don’t understand your brand.
