An ad exchange functions as a digital marketplace where publishers sell ad inventory and advertisers buy it programmatically. Real-Time Bidding (RTB) is the auction mechanism that powers transactions within most ad exchanges. Specifically, RTB enables advertisers to bid on individual ad impressions in real time as users load web pages or apps, allowing the ad exchange to dynamically match the highest bidder with the available inventory. This relationship is critical because without RTB, ad exchanges would lack the automated, instantaneous auction process that maximizes yield for publishers and targeting efficiency for advertisers. RTB provides the operational backbone that transforms the ad exchange from a static marketplace into a dynamic, data-driven platform capable of optimizing ad spend and inventory monetization at scale. Thus, RTB is the enabling technology that allows ad exchanges to deliver precise audience targeting, price discovery, and inventory allocation in milliseconds, making their integration essential for effective programmatic advertising strategies.
