Multi-channel refers to a business strategy that uses various platforms to reach customers. These platforms can include physical stores, websites, social media, and mobile apps. By engaging customers through multiple channels, businesses aim to provide a seamless shopping experience and cater to different preferences. This approach allows customers to interact with a brand in the way that suits them best. For example, a customer might browse products on a website, purchase them through a mobile app, and pick them up at a physical store. Multi-channel strategies help businesses increase their reach and improve customer satisfaction.
