The main role of advertising is to convince prospective buyers to buy a product or service. Advertising aims to persuade potential customers to choose a particular product over others by highlighting its benefits and unique features. It is intended to create awareness, generate interest, and ultimately drive sales. Advertising may also inform people about where to obtain goods and services, but its primary objective is to persuade people to make a purchase. Additionally, advertising may capture the attention of people through creative and engaging advertisements, but this is usually done in service of convincing them to buy the product being advertised.
