An ad exchange is really a digital marketplace where advertisers (buyers) and publishers (sellers) purchase and sell ad inventory through real-time bidding (RTB). It functions as a platform that allows the automated selling and buying of online ad space, allowing advertisers to bid on impressions—opportunities to display an ad with a user—in milliseconds.

Advertisers take advantage of greater transparency and assurance about where their ads will appear.

3. Programmatic Direct
Programmatic direct is really a method where ad inventory is sold without resorting to real-time bidding.
