Marketing is the activity, set of institutions, and processes for creating, communicating, delivering, and exchanging offerings that have value for customers, clients, partners, and society at large

(2) determination of its price,
(3) selection of a distribution channel to reach the customer's place, and
(4) development and implementation of a promotional strategy.

Engagement marketing
Engagement marketing, sometimes called "experiential marketing," "event marketing," "on-ground marketing," "live marketing," or "participation marketing," is a marketing strategy that directly engages consumers and invites and encourages consumers to participate in the evolution of a brand. Rather than looking at consumers as passive receivers of messages, engagement marketers believe that consumers should be actively involved in the production and co-creation of marketing programs, developing a relationship with the brand.
Consumer Engagement is when a brand and a consumer connect. According to Brad Nierenberg, experiential marketing is the live, one-on-one interactions that allow consumers to create connections with brands. Consumers will continue to seek and demand one-on-one, shareable interaction with a brand.
