What is an ad exchange?
An ad exchange is a type of online marketplace of unsold display ad space (belonging to sites or networks) which allows publishers and advertisers to buy and sell ad inventory automatically. It improves transparency and targeting by auctioning impressions in real-time between multiple bidders- allowing for publishers to get the best price on their space and for the advertiser to target the most accurate audience. Additionally, it reduces the cost of a middleman by making this a direct buy.
