What is surely an Ad Exchange?
An ad exchange is often a digital marketplace where advertisers (buyers) and publishers (sellers) exchange ad inventory through real-time bidding (RTB). It functions being a platform that enables the automated buying and selling of online ad space, allowing advertisers to bid on impressions—opportunities to show off an ad to some user—in milliseconds.
