Digital marketing is a field that involves the use of various digital channels and techniques to promote products or services to customers. A product manager is responsible for the development and management of a product throughout its lifecycle, from conception to removal from the market. There is some overlap between the roles of a digital marketer and a product manager, as both involve understanding customer needs and developing strategies to meet those needs. However, a product manager typically has more responsibility for the overall direction and success of a product, while a digital marketer focuses more on promoting the product through digital channels.
