Real-time bidding (RTB) revolutionizes online advertising by enabling instantaneous auctions for ad impressions. When a user visits a webpage, the publisher's ad server sends a bid request to a supply-side platform (SSP), detailing audience demographics and ad slot specifications. The SSP then broadcasts this request to various demand-side platforms (DSPs), which represent advertisers. DSPs evaluate the impression based on their campaign's targeting criteria and submit bids within milliseconds. The SSP conducts an auction, typically a second-price auction, selecting the highest bidder. Finally, the winning advertiser's ad is immediately delivered and displayed on the user's screen. This entire process occurs in the blink of an eye, ensuring relevant ads are shown to the right users at the precise moment. More details: http://energyinnovation.us
