!!! Overview
[{$pagename}] ([RTB]) is a means by which [advertising] inventory is bought and sold on a per-impression basis, via programmatic instantaneous auction.[{$pagename}] allows advertising buyers bid on an impression and, if the bid is won, the buyer’s ad is instantly displayed on the publisher’s site.

[{$pagename}] lets advertisers manage and optimize [Advertising] from multiple ad-networks by granting the user access to a multitude of different [networks], allowing them to create and launch advertising campaigns, prioritize networks and allocate percentages of unsold inventory, known as backfill.

[{$pagename}] transaction begins with a user visiting a [website]. 
* This triggers a bid request that uses the [Advertising IDs] for [Identity Correlation] to present demographic [data], browsing history, [Geolocation], and the data about page being loaded. 
* The bid request goes from the publisher to an ad exchange, which submits it and the accompanying data to multiple advertisers who automatically submit bids in real time to place their ads. 
* [Advertisers|Advertisement] bid on each ad impression as it is served. The impression goes to the highest bidder and their ad is served on the page.[citation needed]!! More Information
