There are four main tools used for promotion: advertising, sales promotion, public relations, and direct marketing. Advertising involves paid communication to promote a product, service, or idea. It follows the AIDA model of attracting attention, building interest, creating desire, and prompting action. Sales promotion uses incentives to drive short-term sales increases. Public relations involves managing a company's interactions and relationships with customers, employees, and other stakeholders. Direct marketing communicates directly with consumers through channels like direct mail, catalogs, telemarketing and websites without intermediaries. Effective promotional campaigns involve defining objectives, analyzing target audiences, developing messages, creating media plans, executing the campaign, and evaluating results.
