Omnichannel Advertising is a phase shift from channel-based advertising to customer-centric advertising. Channel-based advertising (social media, search, display, video, etc.) celebrated at some point in time, the current Ad-Tech made the users interact across the traditional channels. Advertisers adapting to the omnichannel approach were able to reach the targeted user across the channel, for example, by showing a video ad on a mobile user’s social media feed. This is a customer-centric approach that is more effective in bringing attention and also driving engagement.
