A logo is the most important visual symbol of a business, and it provides symbolic representation of the values of the company and its products. A quality logo is attractive, attention-getting and memorable. An effective one offers a subconscious reminder to consumers of the brand image of a company.
A logo may or may not include a company name and slogan alongside visual imagery. The logo is one of a few core visual symbols of a company. Characters and color schemes used in advertising are other visual symbols. Companies put logos on all advertising messages as well as on letters, business cards and other correspondence.
