A slogan is a memorable motto or phrase used in a clan, political, commercial, religious, and other context as a repetitive expression of an idea or purpose, with the goal of persuading members of the public or a more defined target group.
The Oxford Dictionary of English defines a slogan as "a short and striking or memorable phrase used in advertising."
Advertising slogans are short phrases used in advertising campaigns to generate publicity and unify a company's marketing strategy. The phrases may be used to attract attention to a distinctive product feature or reinforce a company's brand.
Most corporate advertisements are short, memorable phrases, often between 3 and 5 words. Slogans adopt different tones to convey different meanings.
a tagline (alternatively spelled tag line) is a short text which serves to clarify a thought for, or is designed with a form of, dramatic effect.
Many tagline slogans are reiterated phrases associated with an individual, social group, or product. As a variant of a branding slogan, taglines can be used in marketing materials and advertising.
