Bid Request and Response

  • Bid Request: In programmatic advertising, a bid request is a data packet sent from a publisher’s ad server to an ad exchange, indicating that there is an ad slot available. This request includes details about the ad slot, the user, and the context in which the ad will be displayed.
  • Bid Response: A bid response is what advertisers or their demand-side platforms (DSPs) send in reply to a bid request. It includes the bid price (how much the advertiser is willing to pay for the ad slot) and the ad creative to be displayed if the bid is successful.

Simplest Definition: A bid request and response are the core components of programmatic ad buying, where a publisher requests bids for an ad slot and advertisers respond with their offers.

Why is it Important?

  • For Publishers: It allows them to sell their ad inventory in real-time to the highest bidder, maximizing revenue.
  • For Advertisers: It offers the opportunity to bid on ad spaces that are most relevant to their target audience, optimizing their ad spend.

How Does it Work?

  • Initiation of Bid Request: When a user visits a website, the publisher’s ad server sends out a bid request to various DSPs.
  • Details in Bid Request: This request includes information like user demographics, browsing behavior, the content of the webpage, ad slot size, etc.
  • Bid Response from Advertisers: Advertisers, through their DSPs, evaluate the bid request and respond with a bid price and the ad they wish to display.
  • Ad Selection: The highest bid or the most relevant ad wins, and that ad is then served to the user.

Historical Context

Bid requests and responses became prominent with the rise of programmatic advertising and real-time bidding (RTB) in the early 2010s, revolutionizing how online ad inventory is bought and sold.
