Programmatic Advertising
Definition
Automated buying and selling of digital ad space using software and algorithms. Faster and more efficient than manual ad buying.
What is Programmatic Advertising?
Programmatic advertising uses automated technology to buy and sell digital ad space in real-time. Instead of negotiating directly with publishers, algorithms make buying decisions in milliseconds based on targeting criteria and budgets.
Most display advertising today is programmatic.
How Programmatic Works
- User visits website: A page starts loading
- Auction triggered: Available ad space is offered to advertisers
- Bids submitted: Advertisers' systems evaluate and bid
- Winner selected: Highest eligible bid wins
- Ad served: All happens in under 100 milliseconds
This happens billions of times daily across the internet.
