Open Auction Definition
An open auction, also called RTB (Real-Time Bidding), allows advertisers to bid on available digital ad space in real time. The highest bidder wins the placement, enabling competitive, transparent ad buying across the open internet.
How Open Auction Works
- Publishers list available ad space in ad exchanges.
- Advertisers bid in real time through DSPs (Demand-Side Platforms).
- The highest bidder’s ad is instantly displayed to the user.
- Pricing is often determined by second-price or first-price auction models.
Example of Open Auction
A travel brand bids via a DSP to show retargeting ads on news websites, competing against other advertisers in real time.
Why Open Auction Matters in Advertising
- Increases transparency and access to diverse ad inventory
- Allows real-time, competitive bidding for maximum efficiency
- Supports scalable, programmatic advertising strategies
- Empowers advertisers with more control over reach and pricing
