Technological developments and digitalization have revealed digital channels, mobile channels and new touch points in addition to physical channels through which businesses interact with consumers. Accordingly, changes have occurred in consumer behavior and this has made it necessary for businesses to redesign their business processes. Omnichannel Marketing Strategy emerged as a result of the reflection of this digital transformation on marketing strategies. Omnichannel Marketing Strategy refers to the brand strategy that integrates all available channels to create a seamless shopping experience that increases interaction with different channels and touch points during consumers' journeys to purchase products or services. It is important for businesses to understand consumer behavior in order to design the Omnichannel Marketing Strategy. n order to gain competitive advantage, businesses reach their existing and potential customers through physical, internet and mobile channels and their integration, which will expand their markets and enable one-to-one interaction, design special messages through each channel and deliver personalized products, services and messages. Determining the changing consumer behavior with digitalization, understanding the transition from a multi-channel approach to an integrated channel approach, and customer experience, which is the focal point of the Omnichannel experience, are important issues that need to be emphasized today. At the same time, although the Integrated Channel Strategy offers many opportunities to both businesses and consumers, there are also difficulties in its implementation.
