Domain Spoofing

What is Domain Spoofing?

A form of ad fraud that occurs when a publisher fraudulently declares a domain name in a bid request that’s different from where the ad will actually be run (e.g., the publisher declares “” in the bid request but the ad will actually be served on “”). This is done to trick advertisers into running their ads on sites where they normally wouldn’t and/or to increase the amount the advertiser will pay for the ad placements. It opens advertisers up to brand safety issues, wastes ad dollars by placing ads on low-quality domains, and can be harmful to legitimate publishers whose domain names are being spoofed.
