PubGuru Header Bidding won’t work if any of the required Key-value pairs (KVP) are missing in DFP.
Because of KVPs, every information from Header Bidding is passed to your Ad Server (DFP). KVP is a crucial element in the process that allows the technology to determine how much the bid was, which bidder wins the auction, the ad sizes, etc. It also enables you as a publisher to eventually run a report and conduct some analysis.
