Omnichannel marketing is a strategy that aims to provide a seamless customer experience across all channels and touchpoints, whether the customer is shopping online from a mobile device, a laptop, or in a brick-and-mortar store. It involves the integration of communications and operations to ensure consistent and personalized interactions. Example: A retailer allows customers to order products online, offers in-store pickup, and provides the ability to process returns through either channel, all while maintaining a unified customer profile.
