Definition: Real-time bidding (RTB) is a digital advertising process where ad impressions are bought and sold in real time through automated auctions. When a user visits a website, the available ad space is auctioned instantly, and the highest bidder’s ad is shown—all in milliseconds. RTB allows advertisers to target specific audiences more precisely while publishers maximise revenue from their ad inventory.
Use it in a Sentence: The brand used real-time bidding (RTB) to deliver targeted ads to users browsing travel websites at the exact moment of interest.

3. Maximises Publisher Revenue
By auctioning impressions, publishers ensure ad space goes to the highest bidder in real time.
4. Scalable and Automated
RTB runs on demand-side and supply-side platforms, making ad buying faster and more efficient.
