Answer: promotion
Explanation: In marketing, promotion relates to every sort of marketing interaction used to notify or convince the intended audience about a commodity, brand or problem's relative merits.
A promotion's aim and therefore its promotional strategy may have a broad range, including revenue rises, future product adoption, brand equity development, positioning, strategic response, or brand identity creation.
Promotion encompasses the communication methods used by a salesperson to provide detailed information about the product. It could be both vocal and graphic information.
