Programmatic advertising involves buying and selling digital ad space through an automated bidding process run by machines. It allows advertisers to target specific audiences in real-time across many digital channels like display, social media, video and mobile using automated software. Some key benefits of programmatic advertising include cost efficiency, transparency into where ads are running, and better targeting capabilities to reach specific audiences based on demographics, interests, behaviors and more. Major brands have seen success using programmatic advertising to precisely target consumers most likely to be interested in their products or services.
