Real-Time Bidding (RTB) is a method of buying and selling digital ads through automated auctions that occur in milliseconds. When a user visits a website or app, ad impressions are auctioned to the highest bidder via a DSP connected to an ad exchange. RTB allows advertisers to serve highly relevant ads based on user data and context. It maximizes efficiency, ensures better ROI, and supports precise audience targeting at scale.
