Bid Request
A bid request is a piece of code used to sell display ads and inventory details. It allows visitors to see ads most suited to them, and for multiple advertisers to utilize the same ad spot on a given publisher’s platform.
Computers are extremely fast at processing data and making decisions. With bid requests, the exact ads on the page aren’t determined until visitors reach the app or website. As soon as they do, the bid request is automatically generated to provide information about available impression inventory and consenting visitor demographics (age, gender, location, visited websites, etc.).
This code is used in header bidding, exchange bidding, and real-time bidding (RTB).
