Programmatic advertising refers to the automated trading of digital ad space. Using specialized software and algorithms, decisions are made in a fraction of a second about which ad is shown to which person or target audience.
A common method in programmatic advertising is a lightning-fast auction: As soon as a user opens a website, the system can auction off the ad space on that page in real time. Advertisers automatically bid on it, depending on how well the user or the context matches the predefined target audience.
All of this happens in real time, even before the page has fully loaded. Instead of using blanket ad placements, this allows each individual ad impression to be traded separately, and the winning bidder’s ad to be displayed.
