What Is Real-Time Bidding?
Every time a page loads, an auction happens — advertisers bid on that single impression in real time, and the winner's ad is served before the page even finishes rendering.
First-Price vs. Second-Price Auctions
Both models are used across the programmatic ecosystem today — here's how each works and where it's applied.
First-Price Auction
The highest bidder pays exactly what they bid. This is now the industry standard across most major exchanges, offering more transparency but requiring smarter bid-shading strategies to avoid overpaying.
Second-Price Auction
The highest bidder wins but pays only slightly more than the second-highest bid. Historically used by most exchanges, still found on some legacy inventory sources today.
