What is RTB (Real Time Bidding)?
In the online advertising space, RTB is the way programmatic ads are bought and sold on a per-impression basis – it’s the instantaneous auction of ad space that happens every time a user views a webpage that monetizes programmatically. Very basically, a user visits a website, which generates a bid request for the ad space on that page. The bid request contains information on that user (e.g., IP address, user agent, location, cookie information, etc.). Advertisers bid on the impression based on the information from the bid request and the winner of the auction gets their ad served to that user. This all happens in a fraction of a second.
