RTB means Real time bidding
RTB is a relatively new way of advertising, by real time bidding it is possible for the advertiser to determine realtime what amount is offered for an individual banner impression. This is made possible by linking different data streams from publishers and advertisers. Previously, the purchase was made on the basis of pre-agreed rates (CPM or CPC). RTB allows advertisers to select and better target audiences, resulting in more returns.
