Programmatic advertising
In short
The automated buying and selling of digital advertising inventory using software and predefined campaign parameters.
Programmatic advertising uses software to buy and sell digital advertising inventory. The advertiser defines the campaign’s requirements, and connected systems handle supported buying decisions and delivery workflows.
How the buying process works
A demand-side platform acts for the advertiser. Publisher-side systems make inventory available through the relevant supply arrangements. The buying system evaluates opportunities against campaign inputs such as audience, format, budget, and price.
Real-time bidding is one programmatic buying method. It uses an auction for an available impression. Programmatic arrangements can also use negotiated or fixed-price deals, so programmatic and real-time bidding are not exact synonyms.
The term describes the purchasing process, not a particular creative format. Display, video, and audio inventory can all be bought programmatically where the relevant systems support them.
Illustrative example
A retailer sets a display campaign’s budget, suitable inventory criteria, and creative. A buying platform evaluates eligible opportunities across publishers and submits bids according to the campaign configuration.
The example describes automation, not a guarantee that every impression will reach a valuable customer. Review supply transparency, placement suitability, invalid traffic controls, and total fees. Automated purchasing removes repeated manual transactions; it does not remove the need to decide which inventory is worth buying.
