Real-time bidding (RTB) is a programmatic advertising method where online display ad space is bought and sold on an impression-by-impression basis through real-time auctions that occur within milliseconds of a user visiting a webpage. Advertisers bid on ad impressions for specific audiences in real-time based on user data and can target more valuable users, potentially achieving better results like lower cost-per-acquisition than bulk buying impressions for large audiences.
