What is Real-Time Bidding?
Real-time bidding represents a process where digital ad space undergoes auctioning in real-time, typically within fractions of a second. This mechanism enables advertisers to bid for ad placements on websites and mobile apps instantaneously as users engage with digital content.
The average person encounters between 4,000 and 10,000 advertisements daily, with the majority facilitated through RTB.
The Mechanics of Real-Time Bidding
Digital advertising operates on a supply-and-demand model. Publishers, who own websites and mobile apps, offer ad space to offset operational costs. Advertisers seek to place their ads in front of potential customers. The adtech industry bridges this gap by connecting publishers (supply) with advertisers (demand).
The RTB Revolution
Early internet ad transactions involved manual, labor-intensive processes. Advertisers negotiated directly with websites, creating time-consuming and costly arrangements with limited scalability and measurable success.
RTB has revolutionized this by automating and streamlining ad transactions. Advertisers now compete in micro-auctions, with winning ads loading almost instantly. This automation facilitates billions of digital ad transactions hourly.
The RTB Process Explained
Key Players
- Publishers: Platform owners displaying ads (websites, mobile apps)

- Advertisers: Businesses promoting products/services

The Workflow
- Ad Request: Publishers send ad requests via SSPs to ad exchanges when users visit webpages or open apps
- Bid Submission: Advertisers submit bids through DSPs based on target audience and maximum bid price criteria
- Auction: Ad exchanges conduct real-time auctions using Vickrey auction format (highest bidder wins but pays second-highest price)
- Ad Display: Winning ads display to users within milliseconds
