Discover how programmatic advertising is revolutionizing the digital marketing landscape and how you can leverage it.
What is Programmatic Advertising?
Programmatic advertising refers to the automated buying and selling of digital ad inventory through real-time bidding or direct deals. Instead of the traditional process involving RFPs and manual insertion orders, programmatic technology uses algorithms and machine learning to purchase display space in milliseconds.
How Programmatic Works
When a user visits a website with ad space available, information about the page and the visitor is sent to an ad exchange. Advertisers bid in real-time for the opportunity to show their ad to that specific user. The highest bidder wins, and their ad is instantly displayed. This entire process takes place in the time it takes for a webpage to load.
Key Components
