Real-time bidding (RTB) is an automated process where ad impressions are bought and sold individually through an instantaneous auction. When a user visits a webpage, the publisher's supply-side platform (SSP) or ad exchange sends an ad request containing anonymous user data to various demand-side platforms (DSPs) representing advertisers. Within milliseconds, DSPs evaluate the impression based on their campaigns, audience targeting, and budget, then submit their bids for the opportunity to display an ad. The ad exchange then conducts an auction in real-time, typically a second-price auction, to determine the winning bidder. The ad from the highest bidder is then immediately served to the user's browser, completing the entire transaction before the page even finishes loading.
