Advertising is a form of mass communication used to promote products, services, or ideas. Advertisements aim to attract attention, build interest and desire, and encourage action. Advertisers research strengths, weaknesses, opportunities, and threats to determine unique selling propositions and effective advertising techniques. These techniques include using basic appeals, attention-getting headlines, slogans, testimonials, product characters, comparisons to other products, and repetition to reinforce messages. The goal is to effectively inform and influence consumers.
