Explanation

Persuasive Advertising is a type of product promotion that aims to persuade a consumer for buying a particular product, especially in the presence of several similar products in the same category. In addition to encouraging trial purchase, persuasive advertising can also be used to coax consumers to add and retain a particular brand in their consideration set, thereby increasing the chances of customer loyalty.

Marketers use this form of advertising to generate demand for a new product or service or increase the demand for a product or service that already exists in the market. Comparative approach, where a brand demonstrates its superiority over some other brands in the same product category, is a commonly used form of persuasive advertising.
