Advertising is an important marketing tool that companies use to promote products and services to new customers. While marketing involves broader strategies, advertising specifically shares information about a brand and its offerings through various media platforms. An effective advertising strategy can help businesses in several key ways, such as building brand awareness, educating consumers, boosting reputation, retaining existing customers, acquiring new customers, staying ahead of competition, and increasing sales. Common types of advertising include outdoor advertising such as billboards and toilet advertising.
