Getting started with Unity Exchange#

How it works#

Programmatic advertising is the automated buying and selling of online advertising space. Automation makes transactions efficient, streamlining the process of digital advertising buying and selling. The process is possible because of the nature of standardized advertising placements and sizes, such as video and banner placements.

Programmatic advertising also can leverage technological advancements of data platforms to help target specific audiences, and allows for up to the minute optimizations of the campaign to help reach advertiser key performance indicators.

Overview#

A publishing app submits an ad request to Unity’s exchange, where DSPs can submit a bid for the impression. If the bid wins the auction, Unity pre-caches the ad and only renders it when the user views the ad. At this point, an impression and all other trackers are counted.

1. Unity receives an ad request from a mobile device.
2. Unity makes an HTTP POST request to all bidding partner endpoints.
3. Each bidder must respond within 200 ms (total round-trip). Unity passes this value through the bid request.
4. Unity's Exchange runs a first-price auction based on valid bidder responses.
5. Upon completing the auction, Unity retrieves the winning bid’s HTML and impression trackers to the client for pre-caching.
6. When the player experiences the ad, Unity pings the winning bidder’s nURL to notify the DSP of the impression.
7. The creative renders to the end user, and Unity fires other event trackers along with the creative payload.
