Digital marketing is the promotion of products, services, and ideas using internet-connected and other digital technologies across channels such as search, social media, email, display, mobile apps, and retail media. It integrates data, platforms, and creative content to reach audiences, measure outcomes, and optimize campaigns within evolving privacy, platform, and regulatory constraints.

It encompasses a wide range of activities, including market research, advertising, sales, and brand management, aimed at anticipating and satisfying consumer needs and wants.
