Real-Time Bidding (RTB)

Category: infrastructure

The automated, algorithmic auction process where digital ad impressions are bought and sold within milliseconds as a web page or media stream loads.

RTB is the core mechanical engine of programmatic ad-tech. When a user requests an impression (e.g., loading an article on an information site), the ad server instantly transmits user demographic embeddings, site categories, and context signals down to Demand-Side Platforms (DSPs). Advertisers respond with real-time bids, and a sub-hundred-millisecond Vickrey second-price or first-price auction determines the winning creative wrapper to fetch.

Common Examples

• Our news bias analytics platform integrates with programmatic RTB networks to dynamically monetize our high-volume tracking pages without manual deal-making.
• If your server response times pass seventy milliseconds during the programmatic RTB loop, downstream ad exchanges will automatically drop you from the auction.
